Google Summer of Code 2021 proposal draft


Name: Daniel Swanson


IRC: popcorndude


Timezone: UTC-5

Proposal: UNIpertium[edit]

This project is really 3 projects UNIfied only by the fact that they all start with UNI:

UNIcode Support[edit]

This portion of the project is Ideas for Google Summer of Code/Robust tokenisation. All string processing would be transferred to ICU and all inputs would be normalized. A program would be inserted at the beginning of the pipeline which normalizes incoming text and compilers would emit warnings for non-normalized input.

The normalization will likely be a modified version of NFC. See for discussion.

UNIt-Testing Framework[edit]

Our regression tests are few and far between and almost none of them are run automatically. This part of the project would be the creation of a Grand Unified Unit-Testing Framework™, probably mainly derived from (though I have included time in the schedule for bikeshedding the exact feature set bikeshedding has been rescheduled to before the coding period begins).

I would also plan to enable this testing on all existing repositories unless the maintainers really didn't want it. This will entail converting any existing tests from whatever state they are currently in.

UNIversal Dependencies-Based Structural Transfer[edit]

I have worked out in broad outlines how to get apertium-recursive's rtx-proc to parse a dependency grammar. This third phase would be implementing that concept and seeing if it's actually useful.

If it works, we'll have a way of creating UD parsers (though I suppose we already have that with CG) though I think the more useful thing is that I have some ideas for a UD generator uses the rules for the parser and uses them to reorder a set of relations. The result of that would be a semi-monolingualized syntactic transfer system, where translation pairs could immediately start using the UD parsers in the monolingual repos and would only need rules for particular problematic constructions.

There's probably also cool stuff we could do with treebanks.

Coding Challenge[edit]

Preliminary UD work:

Status as of Feb 9: working Python compiler from minimal formalism to trx.

Feb 23: the coding challenge listed at Ideas_for_Google_Summer_of_Code/Robust_tokenisation can be found here and a draft of the file structure for the unit-testing framework can be found at User:Popcorndude/Unit-Testing.

Mar 2: Unit-testing draft is probably nearly ready to send to the mailing list for discussion.

Mar 2 again: This slight generalization of Tino's regression system should cover pretty much everything we need User:Popcorndude/Regression-Testing without separate unit tests.

Work Plan[edit]

The following work plan is written assuming the number of hours that GSoC recommends (17 or so per week), but it is very likely that having fun or not having much else to do will result in me putting in substantially more time than that. Either this will balance out my inevitable underestimate of the complexity of the task, or I'll end up way ahead and start inventing new tasks for myself.

  • Finalize string-handling coding guidelines
  • Implement/port regression test system
Unicode transition branches ready for merging
Week 5

July 4-10

Prepare Grand Unified Unit-Testing Framework™
  • Test regression system
  • Figure out continuous integration setup
  • Incorporate regression tests into apertium-init

UD experimentation
  • Convert parser output to CONLL-U
  • Transfer of some sort

Yet Another Transfer System
Week 9

August 1-7

Further UD experimentation
  • Try some actual UD grammars
    • See how well it translates with no pair-specific rules, just the reorderings specified by the monolingual grammar
    • See how fast or slow it ends up being
  • Port compiler and whatnot to C++ if it turns out to be any good
Preliminary evaluation of the effectiveness of UD transfer
Week 10

August 8-14

Unknown What I write here will have little bearing on what actually happens and also by not making a plan for this week, I ensure that my overall plan can be at most 90% wrong. Unknown
final evaluation Project done Unicode support with accompanying developer documentation, unit-testing framework for all language and pair repositories, and some potentially useful messing around with UD-based transfer

I have no other commitments this summer and would be able to work on this project full-time.
