Some formalizing
IMHO the LS problem can be reduced to a classification problem:
the context could be a text frame, a bag of words, a tfidf-labelled array etc.
the possible translations for w can be obtained maybe from WordNet? or another dictionary?
We already have a set of attributes (srl and slr) to mark ambiguous words; it would be best to use those. en-ca and en-es have examples -- Jimregan 13:22, 21 June 2009 (UTC)
Awesome :D I'll give it a read in the next days :) Thanks a lot! -- Deadbeef 23:53, 30 June 2009 (UTC)
the classification problem can be solved in various ways: support vector machines, naive-bayes classifier, decision tree etc.
It seems that the WSD problem can be handled with a Inductive Logic Programming-oriented approach, as this paper states: http://www.mt-archive.info/ACL-2007-Specia.pdf
I'm currently trying to introduce probabilistic reasoning into Aleph - the Inductive Logic Programming framework cited in the paper - for a university project, it would be interesting to see how it performs with lexical selection :) I'll commit some code when I get it to work :D
Aleph can be found here: http://www.comlab.ox.ac.uk/activities/machinelearning/Aleph/aleph_toc.html - BEWARE: it's written in Prolog
