Mining Library Catalogues: Best Match Retrieval Based on Exact-Match Interfaces.
J. E. Wolff, Jürgen Kalinski · 1998
The MyView system aims at gathering bibliographic information from a diversity of heterogeneous distributed Internet repositories like electronic journals and traditional libraries. It maintains a personalized warehouse for bibliographic data in a unified scheme which is locally available for browsing, ad-hoc queries, rearrangements and analysis. On the one hand, users should be able to specify their interests in a simple and comfortable way. Building on experiences gained by the information retrieval community we propose sets of weighted terms and bestmatch retrieval for this purpose. On the other hand, many on-line library catalogues exclusively provide a Boolean interface (exact-match retrieval). We therefore have to tackle the problem of mapping a set of weighted terms on an appropriate collection of Boolean queries, while at the same time restrictions of local warehouse resources and the generated net load have to be taken into account. In this paper the mapping problem and optima...
