Ideas for Google Summer of Code/UD and Apertium integration

Tasks

This project would involve working on a number of tasks from the following list:

• UD annotatrix
  • An HTML/JS interface for treebank annotation
• lttoolbox relabelling (tagset conversion)
  • Seamless conversion between Apertium and UD tagsets
  • tagset embeddings for ambiguous ones
• UDpipe --- lttoolbox integration
  • Use Apertium morphological analysers to be soft constraints on lemmatisation and POS/MSD tagging.
• UD mode for language modiules:
  • calling `apertium qtz-ud` should produce conllu file with LEMMA, POS, FEATs, MISC fields filled in
• Apertium lexsel using deps -- integrate with UDPipe, parse sent, allow rels as constraints (?)
• deps with CG (??)
• Integrate legit tokenisers within UDPipe (????)
• set up APERTIUM EMBEDDINGS in UDPipe
• use GF-generated dep trees as constraints on UD parses (relevant to GSoC? idk)
• transfer rules as constraints (dank idea):
  • es-ca will have a (structural) transfer rule X
  • X reorders dependencies
  • parse (es) and use knowledge of a transfer rule to bias parses on ca
• Your idea(s) here

Coding challenge

• Fix one issue in UD annotatrix and send a pull request
• Train UDpipe for a language that is also in Apertium
• Write a tagset equivalence file for a language that is in both Apertium and UD.
