CATVAR: A database of categorial variations for English

We present a new large-scale database called “CatVar” (Habash and Dorr, 2003) which contains categorial variationsof English lexemes. Due to the prevalence of cross-language categorial variation in multilingual applications, our
categorial-variation resource may serve as an integral part of a diverse range of natural language applications. Thus, the
research reported herein overlaps heavily with that of the machine-translation, lexicon-construction, and information-
retrieval communities. We demonstrate this database, embedded in a graphical interface; we also show a GUI for user
input of corrections to the database.
