Ideas for Google Summer of Code

This is the ideas page for Google Summer of Code, here you can find ideas on interesting projects that would make Apertium more useful for people and improve or expand our functionality. If you have an idea please add it below, if you think you could mentor someone in a particular area, add your name to "Interested mentors" using ~~~

The page is intended as an overview of the kind of projects we have in mind. If one of them particularly piques your interest, please come and discuss with us on #apertium on irc.oftc.net, mail the mailing list, or draw attention to yourself in some other way.

Note that, if you have an idea that isn't mentioned here, we would be very interested to hear about it.

Here are some more things you could look at:

• Top tips for GSOC applications
• Get in contact with one of our long-serving mentors — they are nice, honest!
• Pages in the development category
• Resources that could be converted or expanded in the incubator. Consider doing or improving a language pair (see incubator, nursery and staging for pairs that need work)
• Unhammer's wishlist

If you're a student trying to propose a topic, the recommended way is to request a wiki account and then go to

http://wiki.apertium.org/wiki/User:[[your username]]/GSoC2023Proposal

and click the "create" button near the top of the page. It's also nice to include [[Category:GSoC_2023_student_proposals]] to help organize submitted proposals.

Language Data

Can you read or write a language other than English (and we do mean any language)? If so, you can help with one of these and we can help you figure out the technical parts.

Develop a morphological analyser

• Difficulty:
  3. Entry level
• Size: default Unknown size
• Required skills:
  XML or HFST or lexd
• Description:
  Write a morphological analyser and generator for a language that does not yet have one
• Rationale:
  A key part of an Apertium machine translation system is a morphological analyser and generator. The objective of this task is to create an analyser for a language that does not yet have one.

apertium-separable language-pair integration

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  XML, a scripting language (Python, Perl), some knowledge of linguistics and/or at least one relevant natural language
• Description:
  Choose a language you can identify as having a good number of "multiwords" in the lexicon. Modify all language pairs in Apertium to use the Apertium-separable module to process the multiwords, and clean up the dictionaries accordingly.
• Rationale:
  Apertium-separable is a newish module to process lexical items with discontinguous dependencies, an area where Apertium has traditionally fallen short. Despite all the module has to offer, many translation pairs still don't use it.

Bring an unreleased translation pair to releasable quality

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  shell scripting
• Description:
  Take an unstable language pair and improve its quality, focusing on testvoc
• Rationale:
  Many Apertium language pairs have large dictionaries and have otherwise seen much development, but are not of releasable quality. The point of this project would be bring one translation pair to releasable quality. This would entail obtaining good naïve coverage and a clean testvoc.

Develop a prototype MT system for a strategic language pair

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  XML, some knowledge of linguistics and of one relevant natural language
• Description:
  Create a translation pair based on two existing language modules, focusing on the dictionary and structural transfer
• Rationale:
  Choose a strategic set of languages to develop an MT system for, such that you know the target language well and morphological transducers for each language are part of Apertium. Develop an Apertium MT system by focusing on writing a bilingual dictionary and structural transfer rules. Expanding the transducers and disambiguation, and writing lexical selection rules and multiword sequences may also be part of the work. The pair may be an existing prototype, but if it's a heavily developed but unreleased pair, consider applying for "Bring an unreleased translation pair to releasable quality" instead.

Add a new variety to an existing language

• Difficulty:
  3. Entry level
• Size: default Unknown size
• Required skills:
  XML, some knowledge of linguistics and of one relevant natural language
• Description:
  Add a language variety to one or more released pairs, focusing on the dictionary and lexical selection
• Rationale:
  Take a released language, and define a new language variety for it: e.g. Quebec French or Provençal Occitan. Then add the new variety to one or more released language pairs, without diminishing the quality of the pre-existing variety(ies). The objective is to facilitate the generation of varieties for languages with a weak standardisation and/or pluricentric languages.

Leverage and integrate language preferences into language pairs

• Difficulty:
  3. Entry level
• Size: default Unknown size
• Required skills:
  XML, some knowledge of linguistics and of one relevant natural language
• Description:
  Update language pairs with lexical and orthographical variations to leverage the new preferences functionality
• Rationale:
  Currently, preferences are implemented via language variant, which relies on multiple dictionaries, increasing compilation time exponentially every time a new preference gets introduced.

Add Capitalization Handling Module to a Language Pair

• Difficulty:
  3. Entry level
• Size: default Unknown size
• Required skills:
  XML, knowledge of some relevant natural language
• Description:
  Update a language pair to make use make use of the new Capitalization handling module
• Rationale:
  Correcting capitalization via transfer rules is tedious and error prone

Data Extraction

A lot of the language data we need to make our analyzers and translators work already exists in other forms and we just need to figure out how to convert it. If you know of another source of data that isn't listed, we'd love to hear about it.

dictionary induction from wikis

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  MySQL, mediawiki syntax, perl, maybe C++ or Java; Java, Scala, RDF, and DBpedia to use DBpedia extraction
• Description:
  Extract dictionaries from linguistic wikis
• Rationale:
  Wiki dictionaries and encyclopedias (e.g. omegawiki, wiktionary, wikipedia, dbpedia) contain information (e.g. bilingual equivalences, morphological features, conjugations) that could be exploited to speed up the development of dictionaries for Apertium. This task aims at automatically building dictionaries by extracting different pieces of information from wiki structures such as interlingual links, infoboxes and/or from dbpedia RDF datasets.

Dictionary induction from parallel corpora / Revive ReTraTos

• Difficulty:
  1. Hard
• Size: default Unknown size
• Required skills:
  C++, perl, python, xml, scripting, machine learning
• Description:
  Extract dictionaries from parallel corpora
• Rationale:
  Given a pair of monolingual modules and a parallel corpus, we should be able to run a program to align tagged sentences and give us the best entries that are missing from bidix. ReTraTos (from 2008) did this back in 2008, but it's from 2008. We want a program which builds and runs in 2022, and does all the steps for the user.

Extract morphological data from FLEx

• Difficulty:
  1. Hard
• Size: default Unknown size
• Required skills:
  python, XML parsing
• Description:
  Write a program to extract data from SIL FieldWorks and convert as much as possible to monodix (and maybe bidix).
• Rationale:
  There's a lot of potentially useful data in FieldWorks files that might be enough to build a whole monodix for some languages but it's currently really hard to use

Tooling

These are projects for people who would be comfortable digging through our C++ codebases (you will be doing a lot of that).

Python API for Apertium

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  C++, Python
• Description:
  Update the Python API for Apertium to expose all Apertium modes and test with all major OSes
• Rationale:
  The current Python API misses out on a lot of functionality, like phonemicisation, segmentation, and transliteration, and doesn't work for some OSes like Debian.

Robust tokenisation in lttoolbox

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  C++, XML, Python
• Description:
  Improve the longest-match left-to-right tokenisation strategy in lttoolbox to be fully Unicode compliant.
• Rationale:
  One of the most frustrating things about working with Apertium on texts "in the wild" is the way that the tokenisation works. If a letter is not specified in the alphabet, it is dealt with as whitespace, so e.g. you get unknown words split in two so you can end up with stuff like ^G$ö^k$ı^rmak$ which is terrible for further processing.

Extend Weighted transfer rules

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  C++, python
• Description:
  The weighted transfer module is already applied to the chunker transfer rules. And the idea here is to extend that module to be applied to interchunk and postchunk transfer rules too.
• Rationale:

Automatic Error-Finder / Backpropagation

• Difficulty:
  1. Hard
• Size: default Unknown size
• Required skills:
  python?
• Description:
  Develop a tool to locate the approximate source of translation errors in the pipeline.
• Rationale:
  Being able to generate a list of probable error sources automatically makes it possible to prioritize issues by frequency, frees up developer time, and is a first step towards automated generation of better rules.

Web

If you know Python and JavaScript, here's some ideas for improving our website. Some of these should be fairly short and it would be a good idea to talk to the mentors about doing a couple of them together.

Web API extensions

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  Python
• Description:
  Update the web API for Apertium to expose all Apertium modes
• Rationale:
  The current Web API misses out on a lot of functionality, like phonemicisation, segmentation, transliteration, and paradigm generation.

Website Improvements: Misc

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  html, css, js, python
• Description:
  Improve elements of Apertium's web infrastructure
• Rationale:
  Apertium's website infrastructure Apertium-html-tools and its supporting API Apertium APy have numerous open issues. This project would entail choosing a subset of open issues and features that could realistically be completed in the summer. You're encouraged to speak with the Apertium community to see which features and issues are the most pressing.

Website Improvements: Dictionary Lookup

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  html, css, js, python
• Description:
  Finish implementing dictionary lookup mode in Apertium's web infrastructure
• Rationale:
  Apertium's website infrastructure Apertium-html-tools and its supporting API Apertium APy have numerous open issues, including half-completed features like dictionary lookup. This project would entail completing the dictionary lookup feature. Some additional features which would be good to work would include automatic reverse lookups (so that a user has a better understanding of the results), grammatical information (such as the gender of nouns or the conjugation paradigms of verbs), and information about MWEs. See the open issue on GitHub.

Website Improvements: Spell checking

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  html, js, css, python
• Description:
  Add a spell-checking interface to Apertium's web tools
• Rationale:
  Apertium-html-tools has seen some prototypes for spell-checking interfaces (all in stale PRs and branches on GitHub), but none have ended up being quite ready to integrate into the tools. This project would entail polishing up or recreating an interface, and making sure APy has a mode that allows access to Apertium voikospell modules. The end result should be a slick, easy-to-use interface for proofing text, with intuitive underlining of text deemed to be misspelled and intuitive presentation and selection of alternatives. the open issue on GitHub

Website Improvements: Orthography conversion interface

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  html, js, css, python
• Description:
  Add an orthography conversion interface to Apertium's web tools
• Rationale:
  Several Apertium language modules (like Kazakh, Kyrgyz, Crimean Tatar, and Hñähñu) have orthography conversion modes in their mode definition files. This project would be to expose those modes through Apertium APy and provide a simple interface in Apertium-html-tools to use them.

Add support for NMT to web API

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  python, NMT
• Description:
  Add support for a popular NMT engine to Apertium's web API
• Rationale:
  Currently Apertium's web API Apertium APy, supports only Apertium language modules. But the front end could just as easily interface with an API that supports trained NMT models. The point of the project is to add support for one popular NMT package (e.g., translateLocally/Bergamot, OpenNMT or JoeyNMT) to the APy.

Integrations

In addition to incorporating data from other projects, it would be nice if we could also make our data useful to them.

OmniLingo and Apertium

• Difficulty:
  2. Medium
• Size: default Unknown size
• Required skills:
  JS, Python
• Description:
  OmniLingo is a language learning system for practicing listening comprehension using Apertium data. There is a lot of text processing involved (for example tokenisation) that could be aided by Apertium tools.

UD and Apertium integration

• Difficulty:
  3. Entry level
• Size: default Unknown size
• Required skills:
  python, javascript, HTML, (C++)
• Description:
  Create a range of tools for making Apertium compatible with Universal Dependencies
• Rationale:
  Universal dependencies is a fast growing project aimed at creating a unified annotation scheme for treebanks. This includes both part-of-speech and morphological features. Their annotated corpora could be extremely useful for Apertium for training models for translation. In addition, Apertium's rule-based morphological descriptions could be useful for software that relies on Universal dependencies.
