[PR] ctakes-ytex adding Resnik and Faith algorithms [ctakes]
jlpainter opened a new pull request, #12:
URL: https://github.com/apache/ctakes/pull/12
This patch includes code to add 2 additional metrics to the ctakes-ytex framework which replicate the similarity metrics found in the Perl UMLS::Similarity package for Resnik (both intrinsic and without) as well as the Faith algorithms. The new metrics are registered in the ConceptSimilarityService such that they can be called exactly as the other metrics.
Examples were computed and compared with output from the Perl UMLS::Similarity and verified to be the same. However, this requires that when testing against Perl's package, you must specify to use --instrinsic sanchez as the cTakes YTEX implementation of the IC is ONLY using the Sanchez implementation. If you do not specify the Resnik when calling the perl scripts, it will default to the corpus based IC which results in different numbers being produced. Once you force it to use the Sanchez IC, the distance metrics correspond exactly when running against the same UMLS database installed.
