GSoC ideas for student projects

This page lists example ideas for students who would like to take part in Google Summer of Code and be mentored by Tatoeba. To quote GSoC FAQ:

An Ideas list should be a list of suggested student projects. This list is meant to introduce contributors to your project's needs and to provide inspiration to would-be student applicants. It is useful to classify each idea as specifically as possible, e.g. "must know Python" or "easier project; good for a student with more limited experience with C++." If your organization plans to provide a proposal template for the students, it would be good to include it on your Ideas list.

Keep in mind that your ideas list should be a starting point for student proposals; we've heard from past mentoring organization participants that some of their best student projects are those that greatly expanded on a proposed idea or were blue-sky proposals not mentioned on the ideas list at all. A link to a bug tracker for your open source organization is NOT an ideas list.

You can check out the Ideas list for KDE for Google Summer of Code in 2011 to get an idea of what we’re looking for in an ideas list.

If you're a student, you're invited to discuss any of these ideas, as well as propose your own. To contact us, use one of these:

Tatoeba Wall page
Email/Google groups: Tatoeba GSoC mailing list
IRC: Tatoeba on #Freenode, Webchat
XMPP: Tatoeba conference room on chat.jabberfr.org

Current site

Extending current PHP site: programming in PHP, shell tools for maintenance (e.g.: better export scripts?), JavaScript?

Better export scripts

Currently CSV dumps are done weekly. They require the database to be switched into a read-only mode, take 5~10 minutes and do not contain some important information, like tag creator, comments etc. CSV dumps are important for people who cooperate with Tatoeba by creating additional tools, so their quality is vital for a healthy collaboration.

Deliverables: An database export mechanism that:

Dumps all interesting information (everything that's currently in the data dumps plus modification history, sentence comments, the wall etc.)
Can create an incremental dump (faster dumps will allow making them more often)
Provides an interface for collaborators to get notifications about new dumps and allows automatic access.
(Advanced) Provides a stream of updates in form of web sockets or a similar mechanism.

Prerequisite knowledge: a scripting language (Python preferred), PHP, MySQL.

Administrative Scripts

The current site has experienced a couple of crashes and instabilities. We also would like to grow a number of users who are fully capable of administering it with ease and reliability. In order to ease administration and quickly recover from disaster, a number of scripts covering common administrative tasks are needed.

Deliverables: Shell scripts that cover:

backup
adding new languages
getting external services up and running
updating the production site from the repository
deployment on a real server from scratch
monitoring the server and logging load and activity
other necessary tasks

Prerequisite knowledge: a scripting language (Bash, Python, Perl, etc..), possibly familiarity with a build system (ansible, vagrant), and possibly familiarity with setting up and maintaining a monitoring system (newrelic, nagios, cacti, munin)

API

The Tatoeba database is used either through the main website interface or through data dumps. Having a real API that can be called through AJAX and return machine-readable results would provide real-time access for external applications.

Deliverables: A web application that provides a set of API calls for data stored in the current database. The API should cover all data available through the current web interface, including sentence comments, wall comments, recently-added sentences and top recent contributors.

Prerequisite knowledge: a web application language (Python or PHP preferred), MySQL, and a data exchange format such as JSON or XML.

Improvements in user interface for end users

Tatoeba now handles several kinds of queries, but more are desired. The translation interface, in particular, needs improvement. Examples of desired types of queries:

Get all sentences in a given language by a given username that have not yet been translated into a given language.
- For example: Show me all English sentences by CK not yet translated into Japanese.
Same as above, but limited to sentences with audio.
- For example: Show me all English sentences by CK with audio not yet translated into Japanese.
Get all sentences by native speakers of a given language not yet translated into my own native language.
- For example: Show me all English sentences by native speakers not yet translated into Japanese.
Get all sentences in a given language with a certain tag not yet translated into a given language.
- For example: Show me all English sentences with the tag "restaurant".
Same as above, but limited to sentences by native speakers not yet translated into a given language.
- For example: Show me all English sentences by native speakers with the tag "weather" not yet translated into Japanese.
Get all sentences in a given language under a certain length not yet translated into a given language.
- For example: Show me all Japanese sentences less than 50 characters that aren't yet translated into English.
Same as above, but limited to native speaker sentences.
Same as above, but limited to sentences by a given username.
Get all sentences by native speakers of a given language that match a given search keyword that aren't yet translated into a given language.
- For example: Show all English sentences with the word "mountain" that aren't yet translated into Japanese.
Same as above, but limited to native speaker sentences.
Same as above, but limited to sentences by a given username.

Deliverables: Implementation of some (all?) of the above. Project might include additional queries. It would be highly desired to provide a generic way of adding new types of queries.

Prerequisite knowledge: PHP, CakePHP.

Show pronunciation in IPA for sentences

IPA stands for "International Phonetic Alphabet" and is used to describe pronunciation of human languages in an unambiguous way. As such, it helps learning languages whose pronunciation rules are complex (e.g., English). Tatoeba could display IPA pronunciation for each sentence in basically the same way it currently displays pronunciation for Japanese using kana. One possible way of performing the task is to use an external library or application to prepare IPA annotations. For example, eSpeak seems to be able to handle several popular languages and has an IPA converter.

Deliverables: A mechanism that shows IPA pronunciation for some languages (chosen by the student). This can be done server-side (as a standalone service or part of existing code) or client-side (using JavaScript). Mechanism should allow pre-generating pronunciation descriptions and should provide means to manually edit pronunciation later. Mechanism can rely on 3rd party tool to generate pronunciation descriptions.

Prerequisite knowledge: web technology, some web application stack (PHP, Python or CppCMS preferred).

New site & CppCMS

Helping Sysko with tatowiki, tatodb. Extending CppCMS. As the new site is still mostly being planned, there are no specific project ideas for the moment. Please ask on the IRC channel for more information. Note that many projects in this category will have an experimental nature, and their scope highly depends on your skills.

Standalone user tools

Work on shtooka recorder (or swac-record), tatoparser, katoeba and similar tools. Create new tools for advanced contributors and common users, like apps for smartphones.

Android/iPhone application

iPhone users are about 12%, and Android users about 7% of the site visitors. It might help them immensely if they could use a dedicated application

Deliverables: A smartphone application for easy access to Tatoeba. Examples of features:

Querying the online Tatoeba site
Adding sentences
Translating
Performing typical corpus maintenance tasks (linking/unlinking sentences, changing sentence language, tagging etc.)
Access to wall and sentence comments
Recording voice
Offline database access (more difficult!)

Note: It is not expected to implement all of these features during a single GSoC event. Depending on your skills, you might prepare a proposal for a basic set of features (if you don't have much experience in mobile development yet) or a more complex or targeted application (if you do have experience and want to prepare something more feature-complete).

Prerequisite knowledge: Java and Android development or iPhone and iOS developement; using web services.

Streamlined linking of multiple sentences

Where multiple sentences in a source language have the same translation in the target language, make it easy to link those source sentences to the same target translation. Collecting the sentences that are likely to have the same translation could be as simple as presenting sentences in order of creation, since variants of a sentence that vary only in, e.g., the number of the pronoun (where the singular and plural forms of the second person map to the same word in English) are likely to be entered consecutively.

Prerequisite knowledge: JavaScript, possibly Java, possibly SQL

Help bots

Produce bots like those in Wikipedia, to help with maintenance and repetitive tasks such as fixing common mistakes, wrong flag, etc. As on Wikipedia, users that are actually bots should be identified somehow on the website side. Ideally, create a library that could be used as a base to create bots that interact with the Tatoeba website.

Note: this idea would highly benefit from having a real API, which is another project listed here.

Prerequisite knowledge: web

Other ideas

External services, like CK's Temporary Tatoeba site. Other ideas.

SRS deck generator

Spaced Repetition Systems such as Anki or Mnemosyne are a popular tool for learning languages. However, preparing a good SRS deck is a time consuming task. Therefore, an automated way to generate a deck from a list of sentences (e.g., sentences on a Tatoeba list, sentences tagged by some specific tag, etc.) would help language learners.

Deliverables: an application (preferably a web-based one) that would use Tatoeba database (for example in form of a weekly CSV data dump) to create SRS decks for major flash card applications. Examples of features:

Generate a simple deck from a Tatoeba list, tag, or search query.
Generate an N+1-style deck based on user's list of known words and Tatoeba database. (User gives a list of N words that s/he already knows. System chooses a new sentence where exactly one word is unknown, and the rest belong to the already known set.)
Generated decks have proper internal structure (as for Anki decks: proper field scheme is used to store knowledge, so editing is easy).

Prerequisite knowledge: any web stack, however Django or CppCMS are prefered; Python or C++; knowledge about SRS.

Browsable graph of sentences links

Given a sentence, display as a graph like this the linked sentences up to a given depth. The main purpose of such a graph is to show users how Tatoeba is structured at a glance. The current interface doesn’t provide such a view, but it’s important that users understand the actual structure of Tatoeba. This idea could be freely extended to a complete interface allowing linking and unlinking with a click, filter by language, edit sentences, or whatever you can think of.

Deliverables: a web application or a client-side JavaScript program that provides a graph view of a group of sentences, and allows manipulating them. Code can either operate on database directly or use existing or planned APIs.

Note that this idea can be implemented as part of current code base in PHP or as an experimental service for new CppCMS site (preferred).

Prerequisite knowledge: PHP, Python or CppCMS.
