RETRIEVAL DIFFERENCES BETWEEN TERM AND CITATION INDEXING

摘要

A retrieval experiment was conducted to compare online searching using terms as opposed to citations. This is the first study in which a single database was used to retrieve two equivalent sets for each query, one using terms found in the bibliographic record to achieve higher recall, and the other using documents relevant to the sought topic to retrieve other similar documents. This paper reports on the use of a second citation searching strategy. Overall, by using both types of search keys, the total recall is increased. The more surprising finding is that those documents indexed by both types of indexing of the same topic tend to be highly relevant.
