- Abstract
- Stanford University's Socrates II and University of California at Berkeley's Pathfinder are 2 USA World Wide Web based online publication access catalogues under development. They differ in their design language (how an interface functionally and visually communicates to the users). Evaluates each system's interface design and their ability to communicate functionality to users: analyzes design in terms of: colour, buttons, metaphors, layout, and basic and advanced search modes. Concludes that the design languages of both systems have the right directive and have the potential to evolve

- Abstract
- A relevancy-ranking algorithm for a natural language interface to Boolean online public access catalogs (OPACs) was formulated and compared with that currently used in a knowledge-based search interface called the E-Referencer, being developed by the authors. The algorithm makes use of seven weIl-known ranking criteria: breadth of match, section weighting, proximity of query words, variant word forms (stemming), document frequency, term frequency and document length. The algorithm converts a natural language query into a series of increasingly broader Boolean search statements. In a small experiment with ten subjects in which the algorithm was simulated by hand, the algorithm obtained good results with a mean overall precision of 0.42 and mean average precision of 0.62, representing a 27 percent improvement in precision and 41 percent improvement in average precision compared to the E-Referencer. The usefulness of each step in the algorithm was analyzed and suggestions are made for improving the algorithm.
- Content
- "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."

- Abstract
- By the mid 1980s online bibliographic systems retrieved excessively large sets. Conversely, with standard Boolean systems, searches retrieved commonly nothing or too few records. In Nov. 92, 32% of searches yielded nothing from a retrieval set averaging 98. Offers solutions to these problems using MELVYL as a case study. Examines how non topical data such as date, language and location of document can improve topical searches. Explains OASIS and front end phototyping. Discusses adaptive retrieval, strategic commands, expanded retrieval and developments of OASIS. Covers aggregation of filtered sets, related terms, automatic progressive truncation, the SUMMARIZE LIBRARIES command, filing and filtering and collection analysis

- Abstract
- Subject access in the OPAC, as discussed in this article, is predicated on two different kinds of searching: subject (authority, alphabetic, or controlled vocabulary searching) or keyword (uncontrolled, free text, natural language vocabulary). The literature has focused on demonstrating that both approaches are needed, but very few authors address the need to integrate keyword into authority searching. The article discusses this difference and compares, with a query on the term garbage, search results in two online catalogs, one that performs keyword searches through the authority file and one where only bibliographic records are included in keyword searches.

- Abstract
- Online public access catalogues enable users to undertake subject searching by classification schedules, natural language, or controlled language terminology. In practice the 1st method is little used. Controlled language systems require indexers to index specifically and consistently. A comparative survey was made of indexing practices at Amsterdam and Mijmegen university libraries. On average Amsterdam assigned each document 3.5 index terms against 1.8 at Nijmegen. This discrepancy in indexing policy is the result of long-standing practices in each institution. Nijmegen has failed to utilise the advantages offered by online cataloges

- Abstract
- Current OPAC show their weakness in terms of ease of use and comprehension of user requests, and more generally in man/machine dialogue. Most OPAC searches are for subjects and these give the word results. Natural language processing techniques exist to reduce these difficulties. In France, natural language processing has been used to access the yellow pages (headings) of the French phone directory and the telematics services directory; examples are included. No doubt the future library systems will use these techniques to make the new OPACs really open, public, accessible and co-operative (user-friendly)

- Abstract
- To an overwhelming extent, storage and retrieval systems were designed for information intermediaries who were specialists in formal, controlled documentation languages (e.g. classification systems, indexing languages) and who were then trained to utilize the query language of each retrieval system. However, with the advent of the microcomputer, there now exists, in the information retrieval industry, an obvious will to tackle both the professional and the personal information markets, as evidences by their more sophisticated yet more user-friendly systems and by the design and marketing of all sorts of interface software (front-end, gateway, intermediary). In order to make full advantage of these systems, the user must be able to master three different languages: the natural language of the discipline, the indexing language, and the system's query language. The author defines and characterizes each of these languages and identifies their issues and trends in the IR cycle and specifically in public online search services. Finally he proposes a theoretical model for the analysis of IR languages and suggests a few research avenues

- Abstract
- Outlines the problems of automated cataloguing systems for Chinese, Japanese and Korean (CJK) language materials. Describes the systems developed by the Research Library Information Network and OCLC in the 1980s, and the second generation system, CJK Plus, released by OCLC in 1993. Outlines how the latter system is being used by the East Asiatic Library at University of Colorado at Boulder
