Wmatrix corpus analysis and comparison tool

Wmatrix is a software tool for corpus analysis and comparison. It provides a web interface to natural language processing tools such as the English USAS and CLAWS corpus annotation tools, and standard corpus linguistic methodologies such as frequency lists and concordances. It also extends the keywords method to key grammatical categories and key semantic domains.
