Abstract

Contribution to an issue on the impact of technological change on libraries and ways in which librarians are applying technology to their collections, services to users and the management of their libraries. Traces the evolution of electronic publishing from the early 60s to the present. Pays particular attention to computer conferencing, and hypermedia.

Abstract

Two years ago the author gave a keynote talk at the Essen Symposium that suggested that technology has lulled librarians into a false sense of security and that there is no real evidence that the increasing use of technology has improved library services at all. This talk carries this theme one stage further, suggesting that technology may actually encourage mediocrity in library and information services

Abstract

Reviews the trend away from a paper based society and towards an electronic society: with the advent of computers, electronic mail, computer conferencing, electronic invisible colleges, and the application of computers to libraries and information networks, and to publishing, with the production of electronic media. Forecasts the advent of the electronic library and the electronic librarian, the decline in the use of present day libraries, technical and library services, and the enhanced and extended role of librarians in the new situation. Predicts the eventual demise of the traditional library with the exception of non research libraries but the enhanced value of the librarians as an information specialist

Abstract

In the monastic library of the Middle Ages, the librarian was essentially a curator, a preserver of collections. For most of history libarians were little more than custodians. The idea of a librarian as a provider of services rather than a collector or preserver of materials, did not emerge until late in the 19th century. Computer and telecommunications technologies have revolutionized the library and greatly expanded the horizons of the librarian. Discusses the ways in which technology has affected the library profession and discusses the role of the librarian in the future. The librarian will increasingly become an information intermediary or information consultant and some will be knowledge engineers involved in the design and construction of information systems and in electronic publishing

Abstract

Reports results of an evaluation of 2 expert systems designed for use in library reference services: ReferenceExpert (RE), developed by Houston University; and SourceFinder (SF), developed by Illinois University at Urbana-Champaign. The test group consisted of 60 graduate students at the initial stage of an intermediate level reference course. The evaluation involved test questions already used in an earlier study (College and research libraries 52(1991) no.5, S.454-465). Results indicated that: there was no significant difference between RE and SF students in the confidence they expressed regarding understanding of their test questions; no significant correlation was found between confidence in understanding the question and success in selecting appropriate sources; only 1/5 of the students agreed that the system they used could be considered 'intelligent'; the majority did not consider the system they used to be 'competent'; almost half agreed that the subject categories provided by the menus were too broad; a little more than half wer not satisfied with the information sources selected by their system; significantly more RE users than SF users agreed that they found the menu interface useful; and a keyword search capability was the feature most often mentioned as a needed system enhancement. Overall results indicated that current expert systems for the selection of reference sources cannot perform as well as experienced subject oriented reference librarians

Rez. in: JASIST 53(2002) no.4, S.321-322 (I. Fourie): "A substantial literature exists on artificial intelligence (AI) and expert systems in general, as well as in Library and Information Science (LIS). Many reports are over-confident and grossly exaggerate the power and potential of artificial intelligence (AI). This is especially true of the first phase of At, and to some extent also of the third phase that is stimulated by developments surrounding the Internet. The middle phase was mostly marked by disillusionment about the potential of Al and expert systems. The confusion around the promises made by AI and the lack of operational success, leaves managers of library and information services with the dilemma of distinguishing between worthwhile research reporting on operational projects and projects that exists only on paper or in the researchers' heads. It is very difficult to sieve between the two when working through the subject literature, and to distinguish between working technology/applications and wishful thinking. This might be one reason why working systems are sometimes ignored. According to Lancaster and Warner, library managers must also look much wider than the LIS literature to note new trends; this can, however, become a daunting task. Against this background the authors report on a study conducted with the support of the Special Libraries Association's Steven I. Goldspiel Memorial Research Grant. The objective of the study was to gain sufficient familiarity with the developments in Al and related technologies to make recommendations to the information service community on what can be applied, and what to expect in the near future. The intention therefore was to focus on systems that are actually operational, and systems that hold potential for the future. Since digital libraries seems an inevitable part of our future, applications concerning them features strongly in the final recommendations. The scope of AI in Library and Information Science depends on the interpretation of the concepts artificial intelligence and expert systems. "If a system has to `behave intelligently' (e.g. make inferences or learn from its mistakes) to qualify as having AI, few such systems exist in any application. On the other hand, if one accepts that a system exhibits AI if its does things that humans need intelligence to do, many more systems would qualify" (p. 107). One example is the field of subject indexing. The same would apply if a more relaxed definition of expert systems is applied as a system that "can help the non-expert perform some task at a level closer to that of an expert, whether or not all the essential components are in place" (p. 107). Most of the AI literature relevant to libraries falls in the field of expert systems. Lancaster and Warner identify (p. 6) expert systems as " a branch of artificial intelligence, even though very few expert systems exhibit true intelligence.""

Abstract

Based partly on chapters in a forthcoming book 'Technology and Management in Library and Information Sciences' by F.W. Lancaster and B. Sandore. Some inportant functions of a research library operating largely in a networked digital environment are illustrated. The ability of artificial intelligence and expert system technologies to contribute to these functions is discussed, in the light of a report from the American Association for Artificial Intelligence, as well as experiences with these technologies in the library world and elsewhere
