== Using Weld for Cryptography in the Zeus e-voting application (https://zeus.grnet.gr). ==


==== Brief Explanation: ====
==== Brief Explanation: ====
Synnefo (https://www.synnefo.org/) is a complete open source cloud stack written in Python that provides Compute, Network, Image, Volume and Storage services. Synnefo exposes an OpenStack-derived API that can be used for third party clients, and is used for its own graphical user interface that powers the Okeanos public cloud infrastructure (http://okeanos.grnet.gr).  Synnefo manages multiple Ganeti clusters at the backend for handling low-level VM operations and can use different storage backends.
Zeus is an e-voting application, in use by thousands of people. It ensures anonymity and verifiability of the entire voting process by using strong cryptographic primitives. In particular, encrypted voter ballots are shuffled and anonymised in a verifiable way before decryption. This is computationally costly, so the Zeus team is constantly looking for ways to improve performance.
 
==== Expected Results ====
Cryptographic operations are very costly and efficient implementations  are essential for real-world production use. For example, when using  Python, the underlying cryptography is typically implemented in C/C++,
with suitable bindings in Python, so that the actual computations happen<nowiki> </nowiki>at a much greater speed than that afforded by the Python interpreter. In this context, in last year’s GSoC we implemented a Zero-Knowledge  Shuffle mechanism in C/C+ and then made it available in Python through Cython. Now we want to try a new optimisation, offered by the use of the Weld framework (<nowiki>http://weld.stanford.edu/).
  </nowiki>Weld offers speed improvements by minimising the number of calls, and
thus memory copy costs, between languages, in our case, between Python
and C. In this GSoC project we want to implement our shuffle operations using Weld, measure the performance benefits, and offer it as a possible optimisation in Zeus.

==== Provide Remote Access via SPICE ====
== Addition of Greek glyphs in Open Source Fonts ==


SPICE [https://www.spice-space.org/] is an opensource solution for remote desktop. It is supported by Qemu, Ganeti, and HTML5.
==== Brief Explanation ====
Many of the Open Source fonts (e.g., available at https://fonts.google.com), do not include glyphs for Greek letters and are therefore useless for using in a Greek environment.


Synnefo can use SPICE in two ways:
The aim of this project is to imporve this situation and add the missing glyphs in the correct Unicode codepoints. The exact set of fonts to be completed will be determined in discussions between the student and the mentor(s).


* To open a console to a VM through the web browser for inspection or troubleshooting
'''This is not a typical programming project. '''If you have never designed fonts before, it is probably not for you.
* To offer remote desktop sessions to the user of the VM


The expected tasks are:
==== Expected Results ====
Full support for Greek text in a number of Open Source fonts.


* Investigate the details of SPICE support for all software in the stack (Qemu/Ganeti/browser) to find out which functionality can be supported end-to-end and whether SPICE can be a full remote desktop solution or just an emergency one for troubleshooting.
==== Knowledge Prerequisites ====
* Design an authenticated Qemu-browser connection. Since the SPICE media stream originates not from the VM itself but from its host, there has to be a way to connect to the browser to the Qemu process of the VM. This connection must only be available to an authenticated user. Currently, Synnefo employs an authenticated proxy server for the VNC port openned by qemu.
Type design, font technologies. Please note that this is a special project, where coding, in the traditional sense, will not be enough.
* Implement the authenticated connection and the relevant UI changes to deliver the feature.


==== RESCUE boot for Synnefo VMs ====
==== Mentors: [https://github.com/zvr Alexios Zavras], [https://github.com/irenevl Irene Vlachou] [https://github.com/thynem Εmilios Τheofanous] ====


When the operating system of the VM cannot boot properly to allow the user to connect to it, the user must have another, safer method to gain access to the VM for fixing it or for extracting data.
== Adding Greek language on NLP library Spacy.io ==
Usually, this means that a CDROM is attached to the VM and the VMs boots from the CDROM instead of its disk.


The expected tasks are:
=== Brief Explanation: ===
Spacy is an open-source Python library for advanced Natural Language Processing. It's a very powerful and modern tool for applying NLP to real world problems. Among other functionality it provides Named Entity Recognition, deep learning integration, part-of-speech tagging and includes built in visualizers for syntax and NER. Spacy supports more than 25 languages but not Greek. Adding the Greek language will provide massive improvements on applying NLP on the Greek language, and allow for actions as Named entity recognition and Part-of-speech tagging


* Find/customize/create suitable rescue images for various OSes, and the tools needed to maintain them.
The procedure is well specified on https://spacy.io/usage/adding-languages, custom language data (stop words, tokenizer exceptions, punctuation rules etc) need to be added and tested.
* Design the mechanism that sets and unsets a VM in RESCUE state.
* Implement the RESCUE mechanism and the attaching of the rescue image.


=== Expected Results ===
The vocabulary, syntax, entities and word vectors for the Greek language. These will be produced with Spacy/gensim, after the language information is successfully added.


==== Other Issues of Interest: ====
The Greek language model with then be added to Spacy.io for usage as a supported language model.


* Telemetry (implementation of OpenStack Telemetry / Ceilometer)
As a real world scenario in order to test the language model, analysis on a large number of Official Greek Government's Gazette (FEK-ΦΕΚ) is proposed, in order to extract entities and categorize these documents.


* Multidatacenter integration
=== Related  repositories ===
https://github.com/explosion/spaCy


* Physical node administration Management Web Console (Add, remove, update a physical node)
=== Knowledge Prerequisites ===
Strong knowledge of the Greek language, Python language fluency and Regular Expressions knowledge are necessary for this.


* Network Management Console

==== Knowledge Prerequisites: ====
== Extraction of Responsibilities per unit in public sector organizations from the Government Gazette ==


·      Python
==== Brief Explanation: ====
The objective of this project is to extend existing Government Gazette(GG) text mining code with Named Entity Recognition features that will allow the identification of Government Directorates and Divisions with the responsibilities assigned to them and the types of services they are required to provide according with their legal framework published in http://www.et.gr/ and the extraction of this information with related metadata (decision number, date of the GG issue). The aim is to link the management units with assigned roles and services per unit(Directorates, Divisions & Sections) and codify this specific information, which is hidden in the GG issue raw text. For this, the PDFs must be downloaded, converted into text and cleaned. Then, syntactic-based heuristics and/or machine learning techniques must be applied to identify specific Named Entities types with references to assigned responsibilities-services per unit(Directorates, Divisions & Sections) and links between the two must be extracted. Metadata concerning the GG issue and decision and/or law number will be also associated with the extracted association. The produced associations will be extracted in a machine usable/structured format (e.g. as RDF triples).


·      Ganeti
==== '''<br> '''Expected Results ====
* A module for manually annotating related entities and responsibilities-services assignment sections in raw text
* A NER module, with trained models for detecting  Governmental Directions and Divisions in raw text
* A module that associates entities with responsibilities and extracts related metadata from the GG issue

== Open source plugin for math and algebra in Moodle ==


== The Transparency Program initiative - Diavgeia ==
==== Brief Description ====
Make the moodle learning environment more functional in relation to mathematics.   Although there are a lot of math editors available for moodle, there is still a lot of functionalities missing in relation to school algebra as an open source plugin


===== Brief Explanation: =====
==== Expected Results ====
* Develop a Moodle plugin with the following functionality.
* Allow the teacher to design math assignments, which the student has to interactively solve. The plugin will provide real time feedback on each answer, whether it’s correct, partially correct or incorrect.
* Give the teacher the ability to assign to students conversions of algebraic representations, (ie the student must make simplifications or factorizations), while the plugin monitors the process performed by the student and give him comments on the correctness of each step.
* The same  functionality must be applied in the case of solving an equation.
* Interoperate with the Geogebra plugin.
* In addition to math-focused functionalities, it would be useful to create a page so that the teacher can write in the so-called “Student Progress Notebook” where the teacher comments on the performance of each student.


Diavgeia is a PHP application with a Mysql backend that is used in order to upload documents to an online public repository. This version of code was used by the Greek government from 2010-2014 as the main repository of public decisions and acts.  Each document is digitally signed and assigned a unique Internet Uploading Number (IUN). The application consists of concrete frontend and backend with different databases for security and perfomance reasons.

== Government Gazette text mining, cross linking, and codification ==
 
==== Brief Explanation ====
The objective of this project is to extend existing Government Gazette text mining code to cross-link legal texts and detect the ministers that sign them. For this the text PDFs need to be downloaded and converted into text. Then, heuristic rules must be applied to detect references to other legal texts, which will be converted into hypertext form. Similar techniques will be used to detect the competent ministers. Two possible extensions are proposed. First, detect amendments incorporated within another law. Second, implement a prototype for editing a law in its codified form (e.g. on GitHub) and automatically creating from the changes the text to be legislated (the differences from the original law).

==  Zeus ==


=== Brief Explanation: ===
==== Mentors: [https://github.com/zvr Alexios Zavras] Georgia Kapitsaki ====


Zeus is an open source e-voting platform (online service available at: https://zeus.grnet.gr/zeus/). It enables secure, verifiable elections, with client-side ballot encryption and anonymity guaranteed through cryptographic mixing networks (mixnets). Zeus has already been used in hundreds of elections with tens of thousands of voters.
== Files DB ==


=== Related GitHub repositories: ===
More details in the separate page [https://ellak.gr/wiki/index.php?title=FilesDB FilesDB].


https://github.com/grnet/zeus
==== Brief Explanation ====


=== Example Improvements: ===
A system to keep meta-data for a large number of files.


====Better management/reporting of cryptographic identifiers and proofs====
The files that are to be processed can be on the filesystem, in archives, or parts of a (git) repository. The metadata are mainly information about the contents (size, type, hashes, ...), so that afterwards a number of questions can be asked about the actual files: how many files, how many files larger than X, how similar are two archives/repositories, when was a file introduced in a repository, etc.


Zeus employs cryptographic identifiers and proofs to create a secure log of the entire voting process. These can be used to audit the election after it has been completed and verify that the election protocol has been executed correctly.
This is a brand-new project; some analysis has been done but no code is available yet.


This information, however, has to be presented to the voters and trustees at various stages in the process, and especially at the end, when they have to be recorded into official documents publishing the results.
==== Expected Results ====
A software to collect the data from the input files and a collection of commands to query the data. These can all be command-line utilities; it would be worthwhile to also provide a Web interface, although it is not necessary.


We would like to enhance security and safety by making better use and better presentation of the available cryptographic information.
==== Knowledge Prerequisites ====


For example we could upgrade a cryptic hexadecimal fingerprint at the bottom of the page into a button that will provide a detailed report about the process for auditing or (expert) user inspection, or we could include more validations concerning cryptographic fingerprints into the browser code implementing the voting booth.
C and/or Python; SQL; Git (and other systems); web


====Mixnet Implementations====


The core operation that ensures both integrity and secrecy for e-voting is the mixnet. Zeus employs a re-encryption mixnet protocol that shuffles and re-encodes ballots to make them untraceable to the voter that submitted them while providing a proof that the shuffled votes are indeed equivalent to the original ones.
==== Mentors: [https://github.com/zvr Alexios Zavras] [https://users.ionio.gr/~sarantos/en.html Sarantos Kapidakis] ====


This is a complex and very computationally expensive operation. Better and faster protocols exist. Not all of the available mixnet protocols are appropriate for use in Zeus, but we are considering a few of them.
== CScout AJAX-based Interface ==


In this context, Zeus is participating in a research project that aims to provide (among other privacy-enhancing solutions) a re-encryption mixnet appropriate for e-voting. You can learn more  about the project here:
==== Brief Explanation ====


* https://panoramix-project.eu/
CScout is a source code analyzer and refactoring browser for collections of C programs. It can process workspaces of multiple projects (a project is defined as a collection of C source files that are linked together) mapping the complexity introduced by the C preprocessor back into the original C source code files. CScout takes advantage of modern hardware (fast processors and large memory capacities) to analyze C source code beyond the level of detail and accuracy provided by current compilers and linkers. The analysis CScout performs takes into account the identifier scopes introduced by the C preprocessor and the C language proper scopes and namespaces. CScout has already been applied on projects of tens of thousands of lines to millions of lines, like the Linux, OpenSolaris, and FreeBSD kernels, and the Apache web server.


* https://www.youtube.com/watch?v=xyh631UUhhg
The aim of this project is to redesign the current web interface, which is based on HTML forms generated by C++ code, into a responsive AJAX-based one. Under this scheme the C++ code will provide JSON data through a RESTful interface, which the JavaScript front-end will use.


You can also see some of our recent works on mixnets here:
==== Expected Results ====


* https://github.com/grnet/ac16
A modern responsive web interface offering the current capabilities of CScout.
Ideally this would include in-line editing of identifiers.


We seek to implement or enhance or test different mixnets in order to replace the current mixnet algorithm in Zeus.

====Better PDF Generation and Mobile-friendly Browser View====
==== Knowledge Prerequisites ====


Zeus supports a lot of different voting systems and quite complex formats for ballots. We would like to enhance the experience of users by making all this complexity understandable and pleasantly presentable.
* C++
* JavaScript
* A modern development framework for interactive web content


Zeus can already be used on mobile devices, but the experience can be improved. Mobile devices are increasingly popular, and we assume that participation to elections would get a boost if we make it easy for users to follow and vote for an election while they are on the run.
==== Mentor: [https://www.spinellis.gr Diomidis Spinellis] [http://www.csd.auth.gr/en/staff/faculty?view=user&ro=1&id=14 Stamelos Ioannis] ====


As a second step, of course, the fact that handheld devices are personal can help us enhance the overall security of the application.
== WSO2 Identity Server Userstore using Web Services  to get claims ==


====Voting Systems and Ballots Specification====
==== Brief Explanation ====


Zeus supports a variety of voting systems (approval voting, scored voting, ranked voting) and ballots with simple questions or more complicated designs. We would like to develop a specification to describe voting systems, ballot designs, and cryptographic protocols, so that whole elections can be set up by using descriptions based on this specification.
WSO2 Identity Server provides secure identity management for enterprise web applications, services, and APIs by managing identity and entitlements of the users securely and efficiently. The Identity Server enables enterprise architects and developers to reduce identity provisioning time, guarantee secure online interactions, and deliver a reduced single sign-on environment. WSO2 Identity Server is fully open source and is released under Apache Software License Version 2.0.  


====Separation in multiple independent services (Booth / Ballot box / Registry)====
The aim of this project is to create a new type of userstore where credentials will be separeted from attirbutes and attributes (claims) will be able to be configured from the web UI as a SOAP or REST web service. The end-user should be able to
* configure credentials for LDAP or JDBC
* configure web service authentication
* configure claims to consume the above web service
'''Expected Results'''


Currently Zeus is operating from a single server. However, the e-voting process comprises several distinct components.
A new userstore where end-user can configure using existing web interface, user claims through web services  client. The appropriate changes in the source code should be uploaded in the upstream branch of the latest version (5.4.0)


* The electoral registry that lists and authenticates voters.
==== Related GitHub repository ====
* The voting server that creates and manages the voting process.
https://wso2.github.io/
* The voting booth that records the voter's choices and encrypts them on the voter's computer.
* The mixnet servers that perform the anonymization of votes.


We are already working on some of them but there is a lot of work to be done. The separation into independent components can offer maintainability, flexibility to extend Zeus to support more workflows, even beyond strictly voting (e.g. auction bidding), and most importantly, it can offer better security by allowing different parties to control different components.
https://wso2.github.io/using-maven.html


====Port Cryptographic Workflow to Elliptic Curves====
https://wso2.github.io/github-repositories.html#IS


Zeus uses integer modulo prime arithmetic to construct its cryptosystem. Elliptic curve cryptography may provide some advantages in terms of security or efficiency and we would like to port Zeus cryptography on elliptic curves.

== WSO2 Identity Server  Greek i18n translation ==


== Linked Economy: a framework for Economic Linked Open Data ==
==== Brief Explanation ====


==== Brief Explanation: ====
WSO2 Identity Server provides secure identity management for enterprise web applications, services, and APIs by managing identity and entitlements of the users securely and efficiently. The Identity Server enables enterprise architects and developers to reduce identity provisioning time, guarantee secure online interactions, and deliver a reduced single sign-on environment. WSO2 Identity Server is fully open source and is released under Apache Software License Version 2.0.  
Linked Economy (http://linkedeconomy.org) provides a common understanding on what data are available and how they can be orchestrated to provide relevant insights on e-government topics.
The project has included data from European and other governments and can be scalable to include any similar content from around the world (e.g. UNdata, a data access system to UN databases - http://data.un.org/).  
The Linked Economy platform provides an innovative and value-added resource base for research and education for information technologies in the field of public governance (e-government) employed by lawyers, social scientists and technologists

==== Expected Results ====
# Implementation of a query answering system which will translate natural language queries to SPARQL queries. This system will offer ordinary citizens a way to examine the legality and good administration of Diavgeia, without posing SPARQL queries by themselves.
# Find a way to ensure the integrity of the SPARQL endpoint. For the time being, decisions are stored both as compressed Notation3 files in the filesystem of Diavgeia and in Jena Apache’s triple store. The Stamper tool which is responsible for storing Notation3 decisions on the bitcoin blockchain, ignores the fact that these decisions are also stored on the triple store. That means that a modification/deletion of a decision from the triple store will go unnoticed. Students may have to implement a “Full Verification Procedure”. This procedure will extend the functionality of the Consistency Verifier tool, which will not only consider the computation of the Merkle Tree of Notation3 decisions, but it will also check that for each Notation3 decision, all related data is also offered through the SPARQL endpoint.
# Consistency Verifier tool makes requests to the chain.so explorer in order to read the Merkle Root and compare it to the computed Merkle Root of Notation3 decisions. One may assume that the administration of Diavgeia influences somehow the functionality of chain.so, and thus “foul play actions” may go unnoticed. Consistency Verifier may be extended and offer the option to read the root directly from the blockchain (e.g. using the bcoin.js library).

== Sampling and volume approximation ==


https://github.com/ellak-monades-aristeias/donation-box
==== Brief Explanation: ====
Volume computation is a fundamental problem in discrete and computational geometry with many applications in statistics, biology and economics. There is a variety of implemented solutions for that problem but they scale only to low dimensions (typically less than 10). The first implementation that scales to high (i.e. few hundred) dimensions is implemented in the C++ open-source software package VolEsti (https://github.com/vissarion/volume_approximation). The package contains algorithms for volume approximation as well as uniform sampling for polytopes. The main purpose of the current project is two-fold: first provide an non-C++ interface to the functionality of  VolEsti and second extend and improve VolEsti features.


==== Expected Results ====
The coding project could be divided in the following steps: 


Feature 1 - Improve Custom Wordpress theme
# Understand the code structure and design of VolEsti as well as the implemented algorithms.
# Re-evaluate the dependency from some libraries. For example VolEsti depends on CGAL for linear programming but this is inefficient for high dimensions. Therefore, a goal is to rewrite parts of code to remove CGAL dependency and use an open-source library for convex optimization.
# Implement new features: new sampling and volume computation algorithms, support for polytopes given by the set of vertices of the convex hull, support for spectahedra.
# Create an non-C++ user friently interface, e.g. in python/SciPy/jupyter.
# Writing tests and documentation.


Feature 2 - Donation Box customizations in Wordpress as a plug-in
The steps are generic enough to be easily adapted to student's background and interests.


Feature 3 - P2P or Client - Server, P2P or Client - Server
==== Expected Results: ====
A lot of users such as practicioners or researchers from a variety of scientific fields raging from [https://onlinelibrary.wiley.com/doi/10.1111/geb.12629/full biogeography] to economics need a high level programming or scripting environment to test volume computation or sampling algorithms.

== Files DB ==
== Python PenTest Library (PyPen) ==


More details in the separate page [[FilesDB]].
A collection of tools supporting penetration testers


==== Brief Explanation ====
==== Brief Explanation ====


A system to keep meta-data for a large number of files.
Development of a Python library for penetration testers. The library will include a set of tools for performing the basic tasks for attacking a remote host. It will include reconnaissance tools such as modules that will be able to collect data for a specific target either through the web or through user input. Moreover, other tools will be developed to create custom dictionaries for username and password attacks. Other attack techniques that will be supported include DoS attack, BruteForce attack as well as Inclusion attack. The library will also include various statistical functions for extracting additional information from a captured host.


The files that are to be processed can be on the filesystem, in archives, or parts of a (git) repository. The metadata are mainly information about the contents (size, type, hashes, ...), so that afterwards a number of questions can be asked about the actual files: how many files, how many files larger than X, how similar are two archives/repositories, when was a file introduced in a repository, etc.

== CScout AJAX-based Interface ==
Support for a multilingual front-end (currently only in Greek)


==== Brief Explanation ====
Port it as a moodle plugin


CScout is a source code analyzer and refactoring browser for collections of C programs. It can process workspaces of multiple projects (a project is defined as a collection of C source files that are linked together) mapping the complexity introduced by the C preprocessor back into the original C source code files. CScout takes advantage of modern hardware (fast processors and large memory capacities) to analyze C source code beyond the level of detail and accuracy provided by current compilers and linkers. The analysis CScout performs takes into account the identifier scopes introduced by the C preprocessor and the C language proper scopes and namespaces. CScout has already been applied on projects of tens of thousands of lines to millions of lines, like the Linux, OpenSolaris, and FreeBSD kernels, and the Apache web server.


The aim of this project is to redesign the current web interface, which is based on HTML forms generated by C++ code, into a responsive AJAX-based one. Under this scheme the C++ code will provide JSON data through a RESTful interface, which the JavaScript front-end will use.

Using Weld for Cryptography in the Zeus e-voting application (https://zeus.grnet.gr).

Brief Explanation:

Zeus is an e-voting application, in use by thousands of people. It ensures anonymity and verifiability of the entire voting process by using strong cryptographic primitives. In particular, encrypted voter ballots are shuffled and anonymised in a verifiable way before decryption. This is computationally costly, so the Zeus team is constantly looking for ways to improve performance.

Expected Results

Cryptographic operations are very costly and efficient implementations are essential for real-world production use. For example, when using Python, the underlying cryptography is typically implemented in C/C++, with suitable bindings in Python, so that the actual computations happen at a much greater speed than that afforded by the Python interpreter. In this context, in last year’s GSoC we implemented a Zero-Knowledge Shuffle mechanism in C/C+ and then made it available in Python through Cython. Now we want to try a new optimisation, offered by the use of the Weld framework (http://weld.stanford.edu/). Weld offers speed improvements by minimising the number of calls, and thus memory copy costs, between languages, in our case, between Python and C. In this GSoC project we want to implement our shuffle operations using Weld, measure the performance benefits, and offer it as a possible optimisation in Zeus.

Knowledge Prerequisites

  • Python

Adding Greek language on NLP library Spacy.io

Brief Explanation:

Spacy is an open-source Python library for advanced Natural Language Processing. It's a very powerful and modern tool for applying NLP to real world problems. Among other functionality it provides Named Entity Recognition, deep learning integration, part-of-speech tagging and includes built in visualizers for syntax and NER. Spacy supports more than 25 languages but not Greek. Adding the Greek language will provide massive improvements on applying NLP on the Greek language, and allow for actions as Named entity recognition and Part-of-speech tagging

The procedure is well specified on https://spacy.io/usage/adding-languages, custom language data (stop words, tokenizer exceptions, punctuation rules etc) need to be added and tested.

Expected Results

The vocabulary, syntax, entities and word vectors for the Greek language. These will be produced with Spacy/gensim, after the language information is successfully added.

The Greek language model with then be added to Spacy.io for usage as a supported language model.

As a real world scenario in order to test the language model, analysis on a large number of Official Greek Government's Gazette (FEK-ΦΕΚ) is proposed, in order to extract entities and categorize these documents.

Extraction of Responsibilities per unit in public sector organizations from the Government Gazette

Brief Explanation:

The objective of this project is to extend existing Government Gazette(GG) text mining code with Named Entity Recognition features that will allow the identification of Government Directorates and Divisions with the responsibilities assigned to them and the types of services they are required to provide according with their legal framework published in http://www.et.gr/ and the extraction of this information with related metadata (decision number, date of the GG issue). The aim is to link the management units with assigned roles and services per unit(Directorates, Divisions & Sections) and codify this specific information, which is hidden in the GG issue raw text. For this, the PDFs must be downloaded, converted into text and cleaned. Then, syntactic-based heuristics and/or machine learning techniques must be applied to identify specific Named Entities types with references to assigned responsibilities-services per unit(Directorates, Divisions & Sections) and links between the two must be extracted. Metadata concerning the GG issue and decision and/or law number will be also associated with the extracted association. The produced associations will be extracted in a machine usable/structured format (e.g. as RDF triples).


Expected Results

  • A module for manually annotating related entities and responsibilities-services assignment sections in raw text
  • A NER module, with trained models for detecting  Governmental Directions and Divisions in raw text
  • A module that associates entities with responsibilities and extracts related metadata from the GG issue

Open source plugin for math and algebra in Moodle

Brief Description

Make the moodle learning environment more functional in relation to mathematics.   Although there are a lot of math editors available for moodle, there is still a lot of functionalities missing in relation to school algebra as an open source plugin

Expected Results

  • Develop a Moodle plugin with the following functionality.
  • Allow the teacher to design math assignments, which the student has to interactively solve. The plugin will provide real time feedback on each answer, whether it’s correct, partially correct or incorrect.
  • Give the teacher the ability to assign to students conversions of algebraic representations, (ie the student must make simplifications or factorizations), while the plugin monitors the process performed by the student and give him comments on the correctness of each step.
  • The same  functionality must be applied in the case of solving an equation.
  • Interoperate with the Geogebra plugin.
  • In addition to math-focused functionalities, it would be useful to create a page so that the teacher can write in the so-called “Student Progress Notebook” where the teacher comments on the performance of each student.

Government Gazette text mining, cross linking, and codification

Brief Explanation

The objective of this project is to extend existing Government Gazette text mining code to cross-link legal texts and detect the ministers that sign them. For this the text PDFs need to be downloaded and converted into text. Then, heuristic rules must be applied to detect references to other legal texts, which will be converted into hypertext form. Similar techniques will be used to detect the competent ministers. Two possible extensions are proposed. First, detect amendments incorporated within another law. Second, implement a prototype for editing a law in its codified form (e.g. on GitHub) and automatically creating from the changes the text to be legislated (the differences from the original law).

Software components and IP management

More details in the separate page Clio.

Brief Explanation

A web-based system to manage data on software components and their relations.

Nowadays every piece of software is including and using many other software components, each one coming with their own license.

The goal of this project is to build a simple web system to be able to (manually) input and maintain this information!

This is a brand-new project; some analysis has been done but no code is available yet.

Expected Results

A complete web-based system to manage the above-mentioned data.

Knowledge Prerequisites

Web (any technology welcome)

Files DB

More details in the separate page FilesDB.

Brief Explanation

A system to keep meta-data for a large number of files.

The files that are to be processed can be on the filesystem, in archives, or parts of a (git) repository. The metadata are mainly information about the contents (size, type, hashes, ...), so that afterwards a number of questions can be asked about the actual files: how many files, how many files larger than X, how similar are two archives/repositories, when was a file introduced in a repository, etc.

This is a brand-new project; some analysis has been done but no code is available yet.

Expected Results

A software to collect the data from the input files and a collection of commands to query the data. These can all be command-line utilities; it would be worthwhile to also provide a Web interface, although it is not necessary.

Knowledge Prerequisites

C and/or Python; SQL; Git (and other systems); web

CScout AJAX-based Interface

Brief Explanation

CScout is a source code analyzer and refactoring browser for collections of C programs. It can process workspaces of multiple projects (a project is defined as a collection of C source files that are linked together) mapping the complexity introduced by the C preprocessor back into the original C source code files. CScout takes advantage of modern hardware (fast processors and large memory capacities) to analyze C source code beyond the level of detail and accuracy provided by current compilers and linkers. The analysis CScout performs takes into account the identifier scopes introduced by the C preprocessor and the C language proper scopes and namespaces. CScout has already been applied on projects of tens of thousands of lines to millions of lines, like the Linux, OpenSolaris, and FreeBSD kernels, and the Apache web server.

The aim of this project is to redesign the current web interface, which is based on HTML forms generated by C++ code, into a responsive AJAX-based one. Under this scheme the C++ code will provide JSON data through a RESTful interface, which the JavaScript front-end will use.

Expected Results

A modern responsive web interface offering the current capabilities of CScout. Ideally this would include in-line editing of identifiers.

The Transparency Program initiative - Diavgeia

Brief Explanation

Diavgeia is an application with a Mysql backend that is used in order to upload administrative decisions to an online public repository. This project participated in GSOC2017 as Diavgeia Redefined and a RDF Schema was implemented, which covers almost every possible decision type and the Notation3 (N3) syntax was adopted.

Related GitHub repositories

https://github.com/eellak/gsoc17-diavgeia

Expected Results

  1. Implementation of a query answering system which will translate natural language queries to SPARQL queries. This system will offer ordinary citizens a way to examine the legality and good administration of Diavgeia, without posing SPARQL queries by themselves.
  2. Find a way to ensure the integrity of the SPARQL endpoint. For the time being, decisions are stored both as compressed Notation3 files in the filesystem of Diavgeia and in Jena Apache’s triple store. The Stamper tool which is responsible for storing Notation3 decisions on the bitcoin blockchain, ignores the fact that these decisions are also stored on the triple store. That means that a modification/deletion of a decision from the triple store will go unnoticed. Students may have to implement a “Full Verification Procedure”. This procedure will extend the functionality of the Consistency Verifier tool, which will not only consider the computation of the Merkle Tree of Notation3 decisions, but it will also check that for each Notation3 decision, all related data is also offered through the SPARQL endpoint.
  3. Consistency Verifier tool makes requests to the chain.so explorer in order to read the Merkle Root and compare it to the computed Merkle Root of Notation3 decisions. One may assume that the administration of Diavgeia influences somehow the functionality of chain.so, and thus “foul play actions” may go unnoticed. Consistency Verifier may be extended and offer the option to read the root directly from the blockchain (e.g. using the bcoin.js library).

Sampling and volume approximation

Brief Explanation:

Volume computation is a fundamental problem in discrete and computational geometry with many applications in statistics, biology and economics. There is a variety of implemented solutions for that problem but they scale only to low dimensions (typically less than 10). The first implementation that scales to high (i.e. few hundred) dimensions is implemented in the C++ open-source software package VolEsti (https://github.com/vissarion/volume_approximation). The package contains algorithms for volume approximation as well as uniform sampling for polytopes. The main purpose of the current project is two-fold: first provide an non-C++ interface to the functionality of  VolEsti and second extend and improve VolEsti features.

The coding project could be divided in the following steps: 

  1. Understand the code structure and design of VolEsti as well as the implemented algorithms.
  2. Re-evaluate the dependency from some libraries. For example VolEsti depends on CGAL for linear programming but this is inefficient for high dimensions. Therefore, a goal is to rewrite parts of code to remove CGAL dependency and use an open-source library for convex optimization.
  3. Implement new features: new sampling and volume computation algorithms, support for polytopes given by the set of vertices of the convex hull, support for spectahedra.
  4. Create an non-C++ user friently interface, e.g. in python/SciPy/jupyter.
  5. Writing tests and documentation.

The steps are generic enough to be easily adapted to student's background and interests.

Expected Results:

A lot of users such as practicioners or researchers from a variety of scientific fields raging from biogeography to economics need a high level programming or scripting environment to test volume computation or sampling algorithms.

University Calendar of Courses and Venues

Brief Explanation

The Aristotle University of Thessaloniki has developed an open source solution for publishing a dynamic university calendar for students and faculty (see working instance http://class.auth.gr). It allows public view of Department calendars, Venue calendars and personal views of student / faculty calendars, based on courses they have registered with, or currently assigned to teach, respectively. It provides info on courses and venues reserved for sessions and exports of personal calendar in iCal format, and also serves as a general course catalog with generalized searches on faculty and courses.

List of tasks for the project:

Abstract the local db interface that draws info on courses and faculty from the student information system, in order to make it independent of the specific institution (AUTh) and more widely available for use elsewhere
