Abstract

The challenge of effectively bringing specific, relevant information from the global sea of data to our fingertips, has become an increasingly difficult one. Discusses how the online information industry, founded on Boolean search systems, may be evolving to take advantage of other methods, such as 'term weighting', 'relevance ranking' and 'query by example'

Abstract

At the most technical core of traditional library science, classification stands as a bridge builder between the past and the future of our field. Anthropologists have long seen classification as a tool for understanding culture. Classification involves the informal embedded in the formal and vice versa. If anthropological/cultural distinctions shape culture, the attempt formally to evaluate and improve those distinctions forms much of what we think of as information systems. We then take cultural cues from the systems so created. In traditional library classification research, there have been two distinct challenges. The first is an ethnographic challenge: What distinctions does this specific group of clients use in forming their knowledge culture? How may we mirror in the thesauri, catalogs, and other search and retrieval tools we create for them? This challenge is one of understanding the sense of vernacular terms. Here the information science researcher becomes an anthropologist-i.e., how to disambiguate terms, decide what distinctions are really necessary, and which are reflections of ephemeral debates or fads? The second challenge is a formal one in two parts, concerning the structure of the information system or tool: - Occam's razor: How many terms can we afford given system capacity, user capability, and the means of distribution? - Structural soundness: Are logical flows followed, are the branches of the tree carrying the right weight in proportion to the trunk, are the means of navigation easily grasped for accurate modeling?
There are no a priori solutions here: each scheme must be taken in its own context of use. Classifications that work in the real world must meet both challenges simultaneously. For example, in studying the history of the International Classification of Diseases, we noted that the designers of this global classification system must constantly make practical tradeoffs between the two challenges. In order to do justice to the range of subtle vernacular terms used by medical personnel around the world, a huge unwieldy list would have to be developed. In order for physicians and other users to actually employ the system, a much shorter key to filling out forms is the only possible alternative. As the Internet, Web, and various digital libraries burst their boundaries and appear on desktops and in homes, the tension between these two challenges deepens. What do we understand about the interplay between vernacular classifications and the more formal structures underlying search engines, online catalogs, and other electronic guides? For groups of users that may be both global and unknown, what is the meaning of joining the two aspects of classification? What is usability in the context of both the Web and the intimate desktop? The combination of the cultural and the formal in turn produces a third challenge-a moral and ethical one. For large-scale systems, whose voices will be heard and whose silenced? Whose culture will become the taken-for-granted and whose the exotic other? Where makers and users of classification systems do not address these questions, silent inequities prevail. The articles in this collection each address this set of issues from a variety of angles.

Abstract

The article discusses the user's perspective of information seeking. A model of the information search process is presented derived from a series of five studies investigating common experiences of users in information seeking situations. The cognitive and affective aspects of the process of information suggest a gap between the user's natural process of information use and the information system and intermediaries' traditional patterns of information provision

Abstract

The paper describes an adaptive information retrieval system that uses heuristic search to sample a document space. IRAS consists of the following parts: (1) the information retrieval a*-algorithm for retrieving relevant documents according to a user's request, and (2) a learning module, based on a knowledge representation system and an approximate probabilistic characterization of relevant documents, to reproduce a user classification of relevant documents and to provide a rule-controlled ranking

Abstract

This paper describes the coming together of two independent programmes developing interfaces which improves access to databases. MenUSE - Menu-based User Search Engine - has been developed to search bibliographic databases whilst HIBROWSE - High Resolution Interface for Database Specific BROWsing and SEarching - is a front-end for searching information stored on structured relational database management systems. Combining the 2 approaches affords the user much greater access capabilities than is possible using traditional retrieval systems. The implications of this are explored in the context of EPOQUE (the European Parliament Online QUEry system) and INSPEC
