- Abstract
- The paradigm shift from the old system centered view to a user centered approach involves new tools needed for accessing library resources under the condition that the user's needs are taken into account. An end-user, who has only a little knowledge of classification systems or thesauri, understands little of the mode of the representation of contents and the use of authority lists. In addition, he will have difficulty in formulating his question in a precise manner. He needs to know better what the library proposes in order to define of what use it would be for him. Many studies have been carried out on the use of controlled vocabularies (classification, authority lists, thesauri) as searching devices. It is surprising to find that relatively little attention has been given to the role of these tools in filtering and browsing processes. We have developed a prototype named CATHIE (CATalog Hypertextuel Interactif et Enrichi) that supports such filtering and interactive reformulation features

- Abstract
- The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

- "Most Web search engines accept natural language queries, perform some kind of fuzzy matching and produce ranked output, displaying first the documents that are most likely to be relevant. On the other hand, most library online public access catalogs (OPACs) an the Web are still Boolean retrieval systems that perform exact matching, and require users to express their search requests precisely in a Boolean search language and to refine their search statements to improve the search results. It is well-documented that users have difficulty searching Boolean OPACs effectively (e.g. Borgman, 1996; Ensor, 1992; Wallace, 1993). One approach to making OPACs easier to use is to develop a natural language search interface that acts as a middleware between the user's Web browser and the OPAC system. The search interface can accept a natural language query from the user and reformulate it as a series of Boolean search statements that are then submitted to the OPAC. The records retrieved by the OPAC are ranked by the search interface before forwarding them to the user's Web browser. The user, then, does not need to interact directly with the Boolean OPAC but with the natural language search interface or search intermediary. The search interface interacts with the OPAC system an the user's behalf. The advantage of this approach is that no modification to the OPAC or library system is required. Furthermore, the search interface can access multiple OPACs, acting as a meta search engine, and integrate search results from various OPACs before sending them to the user. The search interface needs to incorporate a method for converting the user's natural language query into a series of Boolean search statements, and for ranking the OPAC records retrieved. The purpose of this study was to develop a relevancyranking algorithm for a search interface to Boolean OPAC systems. This is part of an on-going effort to develop a knowledge-based search interface to OPACs called the E-Referencer (Khoo et al., 1998, 1999; Poo et al., 2000). E-Referencer v. 2 that has been implemented applies a repertoire of initial search strategies and reformulation strategies to retrieve records from OPACs using the Z39.50 protocol, and also assists users in mapping query keywords to the Library of Congress subject headings."
