ROGET THESAUSUS BASED CATEGORIZATION DICTIONARY

A WordStat categorization dictionary based on the well know Roget thesaurus can now be downloaded from our web site. This dictionary categorizes 100,685 words and phrases into 1042 categories (6 broad classes).

Please note that this dictionary has been created using the 1911 edition of the thesaurus. Many modern words are missing. For this reason, its may not be entirely suitable for use in natural-language processing tasks. It may nevertheless be useful for experimentation as well as for the development of more comprehensive categorization systems.
