- 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
- 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

- Abstract
- Section 1 of this article discusses the concept of bibliographical control and makes a distinction between this term, "bibliographical description," and related terms, which are often confused in the literature. It further discusses the function of bibliographical control and criticizes Patrick Wilson's distinction between "exploitative control" and "descriptive control." Section 2 presents projects for establishing bibliographic control from the Library of Alexandria to the Internet and Google, and it is found that these projects have often been dominated by a positivist dream to make all information in the world available to everybody. Section 3 discusses the theoretical problems of providing comprehensive coverage and retrieving documents represented in databases and argues that 100% coverage and retrievability is an unobtainable ideal. It is shown that bibliographical control has been taken very seriously in the field of medicine, where knowledge of the most important findings is of utmost importance. In principle, it is equally important in all other domains. The conclusion states that the alternative to a positivist dream of complete bibliographic control is a pragmatic philosophy aiming at optimizing bibliographic control supporting specific activities, perspectives, and interests.

- Abstract
- This article is organized in 10 sections: (1) Knowledge Organization (KO) is a wide interdisciplinary field, muck broader than Library and Information Science (LIS). (2) Inside LIS there have been many different approaches and traditions of KO with little mutual influence. These traditions have to a large extent been defined by new technology, for which reason the theoretical integration and underpinning has not been well considered. The most important technology-driven traditions are: a) Manual indexing and classification in libraries and reference works, b) Documentation and scientific communication, c) Information storage and retrieval by computers, d) Citation based KO and e) Full text, hypertext and Internet based approaches. These traditions taken together define very muck the special LIS focus an KO. For KO as a field of research it is important to establish a fruitful theoretical frame of reference for this overall field. This paper provides some suggestions. (3) One important theoretical distinction to consider is the one between social and intellectual forms of KO. Social forms of KO are related to professional training, disciplines and social groups while intellectual organization is related to concepts and theories in the fields to be organized. (4) The social perspective includes in addition the systems of genres and documents as well as the social system of knowledge Producers, knowledge intermediaries and knowledge users. (5) This social system of documents, genres and agents makes available a very complicated structure of potential subject access points (SAPs), which may be used in information retrieval (IR). The basic alm of research in KO is to develop knowledge an how to optimise this system of SAPs and its utilization in IR. (6) SAPs may be seen as signs, and their production and use may be understood from a social semiotic point of view. (7) The concept of paradigms is also helpful because different groups and interests tend to be organized according to a paradigm and to develop different criteria of relevance, and thus different criteria of likeliness in KO. (8) The basic unit in KO is the semantic relation between two concepts, and such relations are embedded in theories. (9) In classification like things are grouped together, but what is considered similar is not a trivial question. (10) The paper concludes with the considering of methods for KO. Basically the methods of any field are connected with epistemological theories. This is also the case with KO. The existing methods as described in the literature of KO fit into a classification of basic epistemological views. The debate about the methods of KO at the deepest level therefore implies an epistemological discussion.
