Abstract

. Currently, most approaches to retrieving textual materials from scientific databasesdepend on a lexical match between words in users" requests and those in or assigned to documents in adatabase. Because of the tremendous diversity in the words people use to describe the same document,lexical methods are necessarily incomplete and imprecise. Using the singular value decomposition(SVD), one can take advantage of the implicit higher-order structure in the association of terms withdocuments...
