Title

¬The performance of cited references as an approach to information retrieval

Source

Journal of the American Society for Information Science. 45(1994) no.5, S.287-299

Abstract

Explores the relationship between the number of cited references used in a citation search and retrieval effectiveness. Focuses on analysing in terms of information retrieval effectiveness, the overlap among posting sets retrieved by various combinations of cited references. Findings from three case studies show the more cited references used for a citation search, the better the performance, in terms of retrieving more relevant documents, up to a point of diminishing returns. The overall level of overlap among relevant documents sets was found to be low. If only some of the cited references among many candidates are used for a citation search, a significant proportion of relevant documents may be missed. The characteristics of cited references showed that some variables are good indicators to predict relevance to a given question
