Ideas for Google Summer of Code/Integration and debugging tools for Grammatical Framework

The objective of this task is to create a suite of tools for Grammatical Framework (GF) to facilitate interoperability with Apertium and other tools. Grammatical Framework has a ton of resources, but people familiar with Apertium may find the way of using them a bit alien. The idea of this task is to make some tools for GF to make it more easily pick-uppable for Apertium developers and users.

Tools

• Morphological analyser
  • Input: Text stream, PGF grammar file
  • Output: Tokenised and morphologically analysed text
• Disambiguator
  • Input: Morphologically analysed text, PGF grammar file
  • Output: The analysed text without the analyses not found in the parse trees below a certain probability threshold (n-best). e.g. 1-best would have only the morphological analyses which are found in the 1-best parse tree.
• Lexicon expander
  • Input:
  • Output: Full form list with surface forms and lexical forms
• Lexical selection
  • Input: ?
  • Output: ?

Coding challenge

• Install Grammatical Framework
• Install Apertium
• Write a program using Haskell or C to retrieve the morphological analysis of a word from the PGF library and print it out in Apertium format. (Note that the gf package in cabal has dependency errors, as of 18/02/2015. To install it, run "cabal get gf", and edit the gf.cabal file. Add "network-uri" to the build-depends in the Executable and Library sections)
