After 23 years at the University of California, Berkeley, Fillmore retired in 1994 and joined Berkeley's International Computer Science Institute. There, he started a project called FrameNet, an on-line structured description of the English lexicon implementing much of what he had earlier proposed more theoretically in his theory of Frame semantics, while implementing the idea of emphasizing example sentences from corpora. In FrameNet, words are described in terms of the frames they evoke. Data is gathered from the British National Corpus, annotated for semantic and syntactic relations, and stored in a database organized by both lexical items and Frames.
