This paper presents a lexicon-based approach to syntactic analysis, l,exicase, and applies it to a lexicon driven computatlolml parsing system. The basic descriptive mechanism in a l,exicase grammar is lexieal features. The properties of lexieal items are represented by contextual and non-contextual features, and generalizations are expressed as relationships among sets of these features and among sets of lexieal entries. Syntactic tree strue,uros are representaed as networks of pairwise dependency relationships among the words in a sentence. Possible dependencies are marked as contextual features on individual lexical items, and Lexicase parsing ix a process of picking out words in a string and attaching dependents to them in accordance with their contextual features. Lexiease is an appro...
