Differentia Extraction Code

Links to individual scripts are shown below, along with a brief description. In addition, a tar archive of the collection is available:
     differentia-extraction.tar.gz.

Main code

extract-differentia.perl: Analyzes dictionary definitions to extract and optionally refine the differentia (distinguishing properties).

disambiguate-parses.perl: Disambiguate parses in relational tuple format by resolving the underlying relations (e.g., for prepositions) and by disambiguating the source and target terms.

est_cue_validities.perl: estimate the cue validities (CV's) of properties for words defined in WordNet (or for relations extracted from definitions).

lexrel2network.perl: purpose is to produce a Bayesian Network given a lexical relation listing.

parse_wordnet_defs.perl: Parse the definitions from the synsets in the specified listing from the wn interface.

Supporting code

ascii2network.perl: create a belief network from an ascii representation.

belief_network.perl: Perl module for producing belief networks in the formats required for BELIEF and MSBN (Microsoft Belief Network).

diagnose-collocations.perl: Performs diagnosis of the collocation features used in a GraphLing WSD experiment in order to determine cases that might be over-generating, etc.

extract_linkages.perl: extract Link grammar relations from the parse output.

graphling.perl: common module for GraphLing scripts.

make_network.perl: produce a series of belief networks given a list lexical relation files.

reweight_relations.perl: re-calculate the weights of the lexical relations in the listing produced by tuple2lexrel.perl using the cue validities information produced by est_cue_validities.perl.

tuple2lexrel.perl: Converts relational tuple output from link grammar (see extract_linkages.perl) into format assumed by lexrel2network.perl.

wordnet.perl: module for accessing the WordNet knowledge base (i.e., WordNet access functions).
