Enhancement of Text Representations Using Related Document Titles
Salton, Gerard; Zhang, Y.
Various attempts have been made over the years to construct enhanced document representations by using thesauruses of related terms, term association maps, or knowledge frameworks that can be used to extract appropriate terms and concepts. None of the proposed methods for the improvement of document representation has proved to be generally useful when applied to a variety of different retrieval environments. Some recent work by Kwok suggests that document indexing may be enhanced by using title words taken from bibliographically related items. An evaluation of the process shows that many useful content words can be extracted from related document titles, as well as many terms of doubtful value. Overall, the procedure is not sufficiently reliable to warrant incorporation into operational automatic retrieval systems.
