Two goals motivate the approach: i avoidance of the need for pre-encoded knowledge and ii applicability across a wide range of text. We identify a set of lexico-syntactic patterns that are easily recognizable, that occur frequently and across text genre boundaries, and that indisputably indicate the lexical relation of interest. We describe a method for discovering these patterns and suggest that other lexical relations will also be acquirable in this way. A subset of the acquisition algorithm is implemented and the results are used to augment and critique the structure of a large hand-built thesaurus. Extensions and applications to areas such as information retrieval are suggested. Consider the following sentence:1 S1 The bow lute, such as the Bambara ndang, is plucked and has an individual curved neck for each string.
