This paper presents a morphological lexicon for English that handle more than 317000 inflected forms derived from over 90000 stems. The lexicon is available in two formats. The first can be used by an implementation of a two-level processor for morphological analysis (Karttunen and Wittenhurg, 1983; Antworth, 1990). The second, derived from the first one for efficiency reasons, consists of a disk-based database using a UNIX hash table facility (Seltzer and Yigit, 1991). We also built an X Window tool to facilitate the maintenance and browsing of the lexicon. The package is ready to be integrated into an natural language application such as a parser through hooks written in Lisp and C. To our knowledge, this package is the only available free English morphological analyzer with very wide coverage. attributes. To improve performance, we used PCKIMMO as a generator on our lexicons to build a diskbased hashed database with a UNIX database facility (Seltzer and Yigit, 1991). Both formats, ...
