== Language Ideas == |
|||
== Language Data == |
|||
These are ideas that involve working with particular languages. |
|||
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. |

|||
| description = Take a released language pair, and drastically improve the performance both in terms of coverage, and in terms of translation quality. This will involve working with dictionaries, transfer rules, scripting, corpora. The objective is to make an Apertium language pair state-of-the-art, or close to state-of-the-art in terms of translation quality. This will involve improving coverage to 95-98% on a range of corpora and decreasing [[word error rate]] by 30-50%. For example if the current word error rate is 30%, then it should be reduced to 15-20%. |
|||
| 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 has quite a broad coverage of language pairs, but few of these pairs offer state-of-the-art translation quality. We think broad is important, but deep coverage is important too. |
|||
| 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. |

|||
| description = Take on an orphaned unreleased language pair, and bring it up to release quality results. What this quality will be will depend on the language pair adopted, and will need to be discussed with the prospective mentor. This will involve writing linguistic data (including morphological rules and transfer rules — which are specified in a declarative language — and possibly [[Constraint Grammar]] rules if that is relevant) |
|||
| description = Create a translation pair based on two existing language modules, focusing on the dictionary and structural transfer |
|||
| rationale = Apertium has a few pairs of languages (e.g. mt-he, ga-gd, ur-hi, pl-cs, sh-ru, etc...) that are orphaned, they don't have active maintainers. A lot of these pairs have a lot of work already put in, just need another few months to get them to release quality. See also [[Incubator]] |
|||
| 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. |

|||
| description = Add a language variety to one or more released pairs, focusing on the dictionary and lexical selection |
|||
| rationale = Apertium-separable is a newly developed module to process lexical items with discontinguous dependencies, an area where Apertium has traditionally fallen short. Despite all the module has to offer, it has only been put to use in small test cases, and hasn't been integrated into any translation pair's development cycle. |
|||
| 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. |

|||
| description = Update language pairs with lexical and orthographical variations to leverage the new [[Dialectal_or_standard_variation|preferences]] functionality |
|||
| rationale = The [https://github.com/apertium/apertium-oci-fra Occitan--French language pair] has been recently published. This language pair is of strategic importance for the Occitan language, as Apertium offers the only machine translation system for this language pair. |
|||

|||
| description = Update a language pair to make use make use of the new [[Capitalization_restoration|Capitalization handling module]] |
|||
| rationale = African languages are not particularly well served by Apertium. The four languages listed are quite important, and are only currently served by commercial machine translation companies such as Google, which makes these language communities dependent on a specific commercial provider. |
|||
| rationale = Correcting capitalization via transfer rules is tedious and error prone, but putting them in a separate set of rules should allow them to be handled in a more concise and maintainable way. Additionally, it is possible that capitalization rule could be moved to monolingual modules, thus reducing development effort on translators. |

== 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. |

These are ideas for modifying things in the translation pipeline. |

|||
| description = Extract dictionaries from linguistic wikis |
|||
| 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. |
|||
| 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. |

| description = Extend lttoolbox (perhaps writing a preprocessor for it) so that it can be used to do the morphological transformations currently done with HFST. And yes, of course, writing something that translates the current HFST format to the new lttolbox format. Proof of concept: Come up with a new format that can express all of the features found in the Kazakh transducer; implement this format in Apertium; Implement the Kazakh transducer in this format and integrate it in the English--Kazakh pair. |
|||
| description = Extract dictionaries from parallel corpora |
|||
| rationale = Some language pairs in Apertium use HFST where most language pairs use Apertium's own lttoolbox. This is due to the fact that writing morphologies for languages that have features such as the vowel harmony found in Turkic languages is very hard with the current format supported by lttoolbox. The mixture of HFST and lttoolbox makes it harder for people to develop some language pairs. |
|||
| 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. |

|||
| description = Update the Python API for Apertium to expose all Apertium modes and test with all major OSes |
|||
| rationale = This will involve designing some changes to our XML dictionary format (see [[lttoolbox]], and implementing the associated changes in the FST compiling processing code. The reason behind this is that many languages have prefix inflection, and we cannot currently deal with this without either making paradigms useless, or overanalysing (e.g. returning analyses where none exist). Flag diacritics (or constraints) would allow us to restrict overanalysis without blowing up the size of our dictionaries. |

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.

|||
| description = Develop a tool to locate the approximate source of translation errors in the pipeline. |
|||
| rationale = In most Apertium language pairs, monolingual dictionaries, bilingual dictionaries, post-generation rule files and structural transfer rule files are all written in XML. While XML is easy to process due to explicit tagging of every element, it is tedious to deal with, particularly when it comes to structural transfer rules. Apertium's precursor, interNOSTRUM, had lighter text based formats. The task involves: (a) designing and documenting an interNOSTRUM-style format for all of the XML language data files in a language pair; (b) writing converters to XML and from XML that are fully roundtrip-compliant: (c) designing a way to synchronize changes when both the XML and the non-XML format are used simultaneously in a specific language pair. |
|||

|||
| description = Ensure [[Apertium-recursive#Further_Documentation|Recursive Transfer]] survives ambiguous or incomplete parse trees |
|||
| rationale = [[Why we trim]] mentions several technical reasons for why trimming away monolingual information is currently needed. Unfortunately, this limitation means that a lot of useful contextual information is lost. It would be ideal if the source language could be fully analyzed independent of target language, with any untranslated part fed back into the source language generator. |

| description = Build a [https://microsoft.github.io/language-server-protocol/|Language Server] for the various Apertium rule formats |
|||
| rationale = Currently, many language pairs use [[Constraint grammar]] as a pre-disambiguator for the Apertium tagger, allowing the imposition of more fine grained constraints than would be otherwise possible. However, current implementation of CG is much slower than most of the other modules in the Apertium pipeline, and it's also very different in terms of syntax to other Apertium modules (dictionaries, lexical selection, transfer rules, etc). There have been a few attempts to create FST versions of CG (see [[User:David_Nemeskey/GSOC_progress_2013]]), but they haven't succeeded. The hypothesis is that a simpler version of CG that supports the main features that CG support (no need to feature parity) would have better adoption and integration within the Apertium pipeline. |
|||
| rationale = We have some static analysis tools and syntax highlighters already and it would be great if we could combine and expand them to support more text editors. |

|||
| rationale = Apertium bilingual dictionaries establish correspondences between lexical forms in a number of language pairs.

The graphs may be directly generated from Apertium bidixes and exploiting using [[Bilingual_dictionary_discovery|ideas that had already been proposed in Apertium]] or using existing [http://linguistic.linkeddata.es/apertium/ RDF representations] of parts of their content, which may benefit from the information coming from being linked to other resources.

| description = Add a spell-checking interface to Apertium's web tools |

| rationale = Many languages have good CG's and fairly large monolingual corpora, but little parallel material. Given a small bidix, fairly large monolingual corpora and good analysers/CG's, we should be able to parse both corpora, translate lemmas and look for similar sentences, turning the differences in their parses into transfer rules. |
|||
| 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.

Latest revision as of 09:15, 4 March 2024
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.
Current Apertium contributors: 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 ~~~
.
Prospective GSoC contributors: 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
(more on IRC), 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 prospective GSoC contributor 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[edit]
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[edit]
- Difficulty:
3. Entry level - Size: Multiple lengths possible (discuss with the mentors which option is better for you)
- 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. - Mentors:
Francis Tyers, Jonathan Washington, Sevilay Bayatlı, Hossep, nlhowell, User:Popcorndude - read more...
apertium-separable language-pair integration[edit]
- Difficulty:
2. Medium - Size: Small
- 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. - Mentors:

Bring an unreleased translation pair to releasable quality[edit]
- Difficulty:
2. Medium - Size: Large
- 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. - Mentors:

Develop a prototype MT system for a strategic language pair[edit]
- Difficulty:
2. Medium - Size: Large
- 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. - Mentors:

Add a new variety to an existing language[edit]
- Difficulty:
3. Entry level - Size: Multiple lengths possible (discuss with the mentors which option is better for you)
- 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. - Mentors:

Leverage and integrate language preferences into language pairs[edit]
- Difficulty:
3. Entry level - Size: Medium
- 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. - Mentors:

Add Capitalization Handling Module to a Language Pair[edit]
- Difficulty:
3. Entry level - Size: Small
- 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, but putting them in a separate set of rules should allow them to be handled in a more concise and maintainable way. Additionally, it is possible that capitalization rule could be moved to monolingual modules, thus reducing development effort on translators. - Mentors:

Data Extraction[edit]
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[edit]
- Difficulty:
2. Medium - Size: Multiple lengths possible (discuss with the mentors which option is better for you)
- 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. - Mentors:

Dictionary induction from parallel corpora / Revive ReTraTos[edit]
- Difficulty:
2. Medium - Size: Medium
- 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. - Mentors:

Extract morphological data from FLEx[edit]
- Difficulty:
1. Hard - Size: Large
- 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 - Mentors:

Python API for Apertium[edit]
- Difficulty:
2. Medium - Size: Medium
- Required skills:
C++, Python - Description:
Update the Python API for Apertium to expose all Apertium modes and test with all major OSes - Rationale:

Robust tokenisation in lttoolbox[edit]
- Difficulty:
2. Medium - Size: Large
- Required skills:
C++, XML, Python - Description:
Improve the longest-match left-to-right tokenisation strategy in lttoolbox to handle spaceless orthographies. - 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. Additionally, the system is nearly impossible to use for languages that don't use spaces, such as Japanese. - Mentors:

More Robust Recursive Transfer[edit]
- Difficulty:
1. Hard - Size: Large
- Required skills:
C++ - Description:
Ensure Recursive Transfer survives ambiguous or incomplete parse trees - Rationale:
Currently, one has to be very careful in writing recursive transfer rules to ensure they don't get too deep or ambiguous, and that they cover full sentences. See in particular issues 97 and 80. We would like linguists to be able to fearlessly write recursive (rtx) rules based on what makes linguistic sense, and have rtx-proc/rtx-comp deal with the computational/performance side. - Mentors:

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. - Mentors:

Website Improvements: Spell checking[edit]
- Difficulty:
2. Medium - Size: Small
- 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 - Mentors:

Add support for NMT to web API[edit]
- Difficulty:
2. Medium - Size: Medium
- 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. - Mentors:
