Lexical-semantic resources have been applied successful to a wide range of Natural Language Processing (NLP) problems ranging from collocation extraction (Pearce, 2001) and class-based smoothing (Clark and Weir, 2002), to text classification (Baker and McCallum, 1998) and question answering (Pasca and Harabagiu, 2001).
wORDNET (Fellbaum, 1998) has significantly influenced research in NLP.
