- Abstract
- The Internet has led to an increase in the quantity and diversity of information available for searching. Furthermore, users are bombarded by a constant barrage of electronic messages in the form of e-mail, faxes, etc. This has led to a plethora of search engines, 'intelligent'agents, etc., that aim to help users in their quest for relevant information, or shield them against irrelevant information. All these systems aim to identify the potentially relevant information in among a large pool of available information. No unifying underlying theory for information discovery systems exist as yet. The aim of this article is to provide a logic-based framework for information discovery, and relate this to the traditional field of information retrieval. Furthermore, the often ignored user receives special emphasis. In information discovery, a good understanding of a user's (sometimes hidden) needs and beliefs is essential. We will develop a logic-based approach to express the mechanics of information discovery, while the pragmatics are based on an analysis of the underlying informational semantics of information carriers and information needs of users

- Abstract
- As part of ongoing investigation of information seeking behaviour of end users in electronic environments, a comparison was made of those users having expertise in a topic area and those with expertise in online searching. Computer scientists and online search specialists conducted assigned searches in a HyperCard database on the topic of hypertext. Both groups of experts were able to conduct successful searches and outperformed a novice control group. Search specialists took slightly less time tahn the domain experts, modified queries by adding terms found in the text, and tended to focus on query formulation. Domain experts focused on the text and used their domain knowledge for further question answering

- Abstract
- It is argued that the current generation of online catalogues do not meet basic user expectations about how to search for information. After a brief examination of virtual reality and its associated technology, a new form of online catalogue, the 'virtual reality library' is proposed. Users browse an information space, a computer-controlled set of shelf orderings for items. Its form, workings and design are investigated in detail. The concept of the virtual reality library is then applied to information resources which either have no physical repository or have one which is not accessible to users

- Abstract
- Colours, icons, graphics, hypertext links and other multimedia elements are variables that affect information search strategies and information seeking behaviour. These variables are culturally constructed and represented and are subject to individual and community interpretation. Hypothesizes that users in different communities (in intercultural or multicultural context) will interpret differently the meanings of the multimedia objects on the Internet. Users' interpretations of multimedia objects may differ from the intentions of the designers. A study in this area is being undertaken

- Abstract
- The economics of information is a cross disciplinary area in which the paradigms from 2 disciplines, economics and information science, operate to influence the conceptualisation of the value of information. In this paper we investigate the relationship between information and economics through an analysis of representational literature on the value of information in both disciplines. It was concluded that whilst the search continues at a theoretical level for a conceptualisation of the value of information which can be operationalised, a pragmatic view should be taken in practice based on the level of analysis and context of examination of the value of information

- Examines the challenge for librarians presented with members of the public wanting to make use of the Internet, who may anticipate that finding information on the WWW is a relative straightforward matter. Looks at the kind of guidance needed in using both the Windows operating system and Web browsers. Points out that users will have to learn how to cope with the frustrations inherent to the current realities of the Internet, and specific problems such as the need for absolute precision when entering Web addresses. Reference interviews may be required to determine whether the Web is the best source for the information sought in a particular instance, to help formulate appropriate search strategies, and evaluate and present the information that users retrieve

- Abstract
- Management information systems (MIS) is a young and dynamic technological discipline that is greatly in need of a theoretical foundation in order to be recognized as an academic field. A key to this search is the construction of a paradigm which engulfs a set of objects that is genuinely indigenous to MIS. This study is a modest attempt to identify this set of objects and to construct a simple model based on them. A basic entity model is constructed to provide a better understanding for the fundamental theory of information. The model identifies the four basic entities which define the scope of information theory and establishes the 4 fundamental postulates which can serve as its foundation. The 4 basic entities are data, information, knowledge, and wisdom. The order of the entity as specified is important. Each entity is transformed to the next higher one during entity processing reduces the entropy of the entity so that further analysis can be executed more systematically. This concept enforces the fact that all computerized information systems also have a similar basic role

- Abstract
- Examines how societal changes influence the involvement of libraries as resources in the learning processes of adults. Libraries are instruments for socialisation, so that when ideologies change they influence libraries. The changes are apparent not only in acquisition policy but also in registration and retrieval. Examines the Swedish classification system as an example of a system with a humanistic signature based on idealism, and Marxist systems based on materialism in former East block countries and China. With computerised information systems, the ideal of international information dissemination without borders, available to all has materialised. The resulting knowledge organisation reflect post-modern ideas. Modern databases using descriptors exemplify the fragmentation which the new information technology creates. Each user shapes a personal view with the help of a chosen search logic and a concept combination. Asks what effect this will have on knowledge organisation, development of cultural traditions and local librarians as agents of change
