For example, deciding which determiner to use when translating from Spanish "su" to English "his, her, its". The objective of this task is to make a system to resolve anaphora and integrate it into a translation pipeline.

| description = Update the web API for Apertium to expose all Apertium modes
−
| 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%.
  
  +
| rationale = The current Web API misses out on a lot of functionality, like phonemisation and segmentation
−
| 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.

−
| 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 &mdash; which are specified in a declarative language &mdash; and possibly [[Constraint Grammar]] rules if that is relevant)

| 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.
−
| 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]]

−
| description = The objective is to start these language pairs (which haven't been started or have currentlu very little data in Apertium) and write an usable version which provides intelligible output.
  
  +
| rationale = Our lexical selection module allows for inferring rules from corpora and word alignments, but the procedure is currently a bit messy, with various scripts involved that require lots of manual tweaking, and many third party tools to be installed. The goal of this task is to make the procedure as user-friendly as possible, so that ideally only a simple config file would be needed, and a driver script would take care of the rest.

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.

−
| skills = C++, XSLT, XML
  
−
| 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.
  
−
| 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.

| difficulty = Hard
  
−
| skills = C++ or Java, XML, Knowledge of FSTs
  
−
| description = Adapt [[lttoolbox]] to elegantly use flag diacritics. Flag diacritics are a way of avoiding transducer size blow-up by discarding impossible paths at runtime as opposed to compile time. Some work has already been done, see [[Flag diacritics]].
  
−
| 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.

−
| description = [[lttoolbox]] is a set of tools for building finite-state transducers. As part of Apertium's long-term strategy we would like to include probabilistic information into more stages of the pipeline to allow generic tools to be optimised for machine translation. This task involves adding the possibility of weighting lexemes and analyses in our finite-state transducer toolbox.

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.

−
| description = Make it possible to edit and develop language data using a format that is lighter than XML
  
−
| 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.

−
| 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.

−
| skills = XML, a scripting language (Python, Perl), C++, finite-state transducers
  
−
| description = Implement a [[Constraint Grammar]]-like module based on finite-state transducers.
  
−
| 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.

Having a unified testing framework would allow us to be able to more easily track quality improvements over all language pairs, and more easily deal with regressions.
−
| rationale = Lots of people use Python, they like to use it in their Jupyter notebooks and on Microsoft Windows™. Apertium is really hard to get going in these kind of environments. So it would be cool if we could make Apertium work for them too. It has a lot of nice language processing tools that we would like more people to use. I'm sure people would love to "pip install apertium" or "pip install apertium-ava". The API/implementation should be pythonistic and should use C++ bindings to directly perform morphological functions, avoiding the overhead of a separate process. Prior GSoC project work is available on [https://github.com/apertium/apertium-python GitHub].

There are various container varieties for different tasks. One such variety, called Translate-Strict-Bitext, represents a bilingual translation job. The 'request' TIPP would contain an XLIFF:doc ([https://github.com/tingley/interoperability-now/tree/master/releases/xliffdoc/1.0.1], a subset of XLIFF 1 [http://docs.oasis-open.org/xliff/v1.2/os/xliff-core.html]) file with the document to be translated and the corresponding metadata, and the corresponding 'response' TIPP would contain the results of Apertium MT applied to it, but taking into account the translation memory provided in the TIPP, if any (using Apertium's -m switch).

−
| rationale = Many language pairs in Apertium are unique, such as Breton-French, and many of them are used for gisting (understanding) purposes. Gap-filling provides a simple way to evaluate the usefulness of machine translation for gisting.

+
| 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]].

Revision as of 22:16, 18 January 2021

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.freenode.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:


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]]/GSoC2020Proposal

and click the "create" button near the top of the page. It's also nice to include [[Category:GSoC_2020_student_proposals]] to help organize submitted proposals.

Ideas

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 phonemisation and segmentation and doesn't work for some OSes like Debian.

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 phonemisation and segmentation

Develop a morphological analyser

  • Difficulty:
    3. Entry level
  • Size: default Unknown size
  • Required skills:
    XML
  • 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.

Support for Enhanced Dependencies in UD Annotatrix

  • Difficulty:
    2. Medium
  • Size: default Unknown size
  • Required skills:
    NodeJS
  • Description:
    UD Annotatrix is an annotation interface for Universal Dependencies, but does not yet support all functionality
  • Rationale:

User-friendly lexical selection training

  • Difficulty:
    2. Medium
  • Size: default Unknown size
  • Required skills:
    Python, C++, shell scripting
  • Description:
    Make it so that training/inference of lexical selection rules is a more user-friendly process
  • Rationale:
    Our lexical selection module allows for inferring rules from corpora and word alignments, but the procedure is currently a bit messy, with various scripts involved that require lots of manual tweaking, and many third party tools to be installed. The goal of this task is to make the procedure as user-friendly as possible, so that ideally only a simple config file would be needed, and a driver script would take care of the rest.

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.

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 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.

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.
