Abstract

Epistemological theories of information science have a fundamental impact on theories about users, their cognition and information seeking behaviour, on subject analysis, and on classification. They also have a fundamental impact on information retrieval, on the understanding of 'information', on the view of documents and their role in communication, on information selection, on theories about the functions of information systems and on the role of information professionals. Asserts that information science must be based on epistemological knowledge, which avoids blind alleys and is not outdated. Shows limitations in the dominant approaches to information science and proposes alternative viewpoints

Abstract

Report on the conference on Information Authority and user knowledge held in Boras Apr 93 and arranged by Gothenburg University's Centre for Library and Information Science and Studies and Boras Library High School. The main speaker, Patrick Wilson, spoke on consequences of information overload and rapid conceptual change. Johan Olaisen's talk on 'toward a theory of clarified subjectivity' started like Wilson's with the problem that users of information systems drown in trivialities. Lena Olsson's dealt with library work in practice and commented on the connection between cognitive authority and professional status of librarians. Discussions centered on the definition of information authority, and on overload as the driving force in IF development

Abstract

Recently, a new book on knowledge organization has been published by Greenwood Press. The title is 'Information seeking and subject representation: an activity-theoretical approach to information science'. This book presents a new general theory for information science and knowledge organization, based on a theory of information seeking. The author is Dr. Birger Hjørland, Royal School of Library and Information Science. In 1994, he presented his work on theory for KO at the 3rd International ISKO conference in Copenhagen. The book aims to provide both a new understanding for the foundations of information science and knowledge organization, and to provide new directions in research and teaching within these fields. KO (Hanne Albrechtsen) has interviewed Birger HjÝrland in Copenhagen about his views on knowledge organization and subject representation

Abstract

Information science (IS) is concerned with the searching and retrieval of text and other information (IR), mostly in electronic databases and on the Internet. Such databases contain fulltext (or other kinds of documents, e.g. pictures) and/or document representations and/or different kinds of 'value added information'. The core theoretical problems for IS is related to the determination of the usefulness of different 'subject access points' in electronic databases. This problem is again related to theories of meaning and semantics. This paper outlines some important principles in the design of documents done in the field of 'composition studies'. It maps the possible subject access points and presents research done on each kind of these. It shows how theorie of IR must build on or relate to different theories of concepts and meaning. It discusses 2 contrasting theories of semantics worked out by Ludwig Wittgenstein: 'the picture theory' and 'the theory od language games' and demonstrates the different consequences for such theories for IR. Finally, the implications for information professionals are discussed

Abstract

This paper takes a second look at three prevailing main themes in knowledge organization: i) the academic disciplines as the main structural principle; ii) the fiction/non-fiction distinction; and iii) the appropriate unit of analysis in online retrieval systems. The history and origin of bibliographic classification [Dewey, Bliss, Mills, Beghtol] are discussed from the perspective of pragmatist philosophy and social studies of science [Kuhn, Merton, Reich]. Choices of structural principles in different schemes are found to rely on more or less implicit philosophical foundations, ranging from rationalism to pragmatism. It is further shown how the increasing application of faceted structures as basic structural principles in universal classification schemes [DDC, UDC] impose rationalistic principles and structures for knowledge organization which are not in alignment with the development of knowledge in the covered disciplines. Further evidence of rationalism in knowledge organization is the fiction/non-fiction distinction, excluding the important role of artistic resources for, in particular, humanistic research. Finally, for the analysis of appropriate bibliographic unit, it is argued that there is a need to shift towards a semiotic approach, founded on an understanding of intertextuality, rather than applying standard principles of hierarchical decomposition of documents. It is concluded that a change in classification research is needed, founded on a more historical and social understanding of knowledge

Abstract

This article presents a theoretical investigation of the concept of 'subject' or 'subject matter' in library and information science. Most conceptions of 'subject' in the literature are not explicit but implicit. Various indexing and classification theories, including automatic indexing and citation indexing, have their own more or less implicit concepts of subject. This fact puts the emphasis on making the implicit theorie of 'subject matter' explicit as the first step. ... The different conceptions of 'subject' can therefore be classified into epistemological positions, e.g. 'subjective idealism' (or the empiric/positivistic viewpoint), 'objective idealism' (the rationalistic viewpoint), 'pragmatism' and 'materialism/realism'. The third and final step is to propose a new theory of subject matter based on an explicit theory of knowledge. In this article this is done from the point of view of a realistic/materialistic epistemology. From this standpoint the subject of a document is defined as the epistemological potentials of that document

Abstract

Information science has for a long time been drawing on the knowledge produced in psychology and related fields. This is reasonable, for the central issue in information science concerns individual users navigating information spaces such as libraries, databases, and the Internet, Thus, informations seeking is the fundamental problem in information science, while other problems, such as document representation, are subordinate. This book proposes a general theory of information seeking as a theoretical basis for information science
