FASIT: A fully automatic syntactically based indexing system
Martin C. Dillon, Ann S. Gray · Journal of the American Society for Information Science · 1983
Abstract The aim of automatic Indexing Is to achieve a compact representation of a document suitable for retrieval. FASIT (Fully Automatic Syntactically based Indexing of Text) Identifies content bearing textual units without a full parse, and, without using semantic criteria, groups these units Into quaslsynonymous sets. Tested on a database of 250 documents and 22 queries, FASIT performed better than both thesaurus and stem based Indexing systems. Retrievals Indicate that the basic Idea of FASIT—that significant terms In the text can be Identified through syntactic patterns—Is valid and that FASIT deserves serious consideration as an advance over stem based systems.
