COMPUTATIONAL, PHONOLOGICAL AND MORPHOLOGICAL LINGUISTICS AND RETRIEVAL STUDIES. REPORT NO. 1: GRAMMARS AND TEXT ANALYSIS.
Abstract
The role of grammatical analysis in processing text for document and message retrieval is first explored, and certain requirements formulated. The utility of transformational grammars in text analysis is then discussed by considering whether transformations are a) meaningpreserving, b) truth-preserving and c) informationpreserving. It is argued that such grammars are generally inappropriate for the retrieval purposes mentioned. A concluding section offers criteria for measuring the simplicity of a grammatical model. (Author)
