CuiTools 0.19

CuiTools is a freely available package of Perl programs for supervised and unsupervised word sense disambiguation experiments.
CuiTools is a freely available package of Perl programs for supervised and unsupervised word sense disambiguation (WSD) experiments. The name CuiTools comes from the Concept Unique Identifiers (CUIs) found in the Unified Medical Language System (UMLS).

This package allows the users to perform supervised or unsupervised word sense disambiguation using information extracted from the UMLS such as CUIs, semantic types and semantic relations as well as general english features such as unigrams, bigrams and part-of-speech information.

What's New in This Release:

For our supervised tools, we incorporated the ability to use the entire functionality provided by the Ngram Statistic Package (NSP) count.pl and statistic.pl programs to obtain features for the machine learning algorithm. This allows ngrams of varying length N to be used as features with the
standard count.pl --frequency, --remove and --stop options. What is unique is that this feature is available not just for words but also for CUIs and semantic types. This functionality also includes measures of association to be obtained to help determine which ngrams should be included in the feature list.

For our converters, we have modified their insides in hopes of making them clearer. We also corrected some errors that were found in the conversion process.
