- Abstract
- Traditional subject cataloguing hampers subject retrieval in central catalogues, because of the lack of a common indexing and retrieval language in these catalogues. This study investigates the possibilities to use the various individual subject access systems, present in the catalogues, for subject access. A search procedure based on 'citation pearl growing' and 'user relevance feedback', which can be applied in a public access interface to central data bases, has been developed. From an experiment it can be concluded, that automated expert assistance, provided with a search strategy, will improve search response for unexperienced searchers. It reduces the number of zero-hits and increases the number of relevant items retrieved
