<p>WinBrill is a part-of-speech tagger developed by Eric Brill in the 1990s for the French language laboratory ATILF. It was originally available for UNIX, with WinBrill optimized for Windows 95/98/NT as of 1999. The ATILP provided a vocabulary and rules files based on FRANTEXT data. Versions of the Brill tagger are still extant online.</p>
