Index Term - Author Keywords

Author Keywords

Many journals and databases provides access (also) to index terms made by authors to the articles being published or represented. The relative quality of indexer-provided index terms and author provided index terms is of interest to research in information retrieval. The quality of both kinds of indexing terms depends, of course, on the qualifications of provider. In general authors have difficulties providing indexing terms that characterizes his document relative to the other documents in the database. Author keywords are an integral part of literature.
