- Abstract
- This paper considers classical bibliographic databases based on the Boolean retrieval model (for example MEDLINE and PsycInfo). This model is challenged by modern search engines and information retrieval (IR) researchers, who often consider Boolean retrieval as a less efficient approach. This speech examines this claim and argues for the continued value of Boolean systems, which implies two further issues: (1) the important role of human expertise in searching (expert searchers and "information literacy") and (2) the role of knowledge organization (KO) in the design and use of classical databases, including controlled vocabularies and human indexing. An underlying issue is the kind of retrieval system for which one should aim. It is suggested that Julian Warner's (2010) differentiation between the computer science traditions, aiming at automatically transforming queries into (ranked) sets of relevant documents, and an older library-orientated tradition aiming at increasing the "selection power" of users seems important. The Boolean retrieval model is important in order to provide users with the power to make informed searches and have full control over what is found and what is not found. These issues may also have important implications for the maintenance of information science and KO as research fields as well as for the information profession as a profession in its own right.

- Abstract
- This article introduces the field of terminology, which often considers the Austrian engineer Eugen Wüster as its founder in the 1930s, although important principles go back in time, in particular to 18th and 19th century botanists, zoologists and chemists. The contributions of Wüster are presented, as well as the alternative theories, with their criticism of Wüster's position, which came to influence the field after 1990. The article further suggests that domain-analytic studies based on epistemological studies of knowledge domains seems to have been overlooked. The relations between terminology and knowledge organization are addressed, and closer cooperation between the two fields is called for.

- 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
- This paper investigates the problem of the labelling of the library, documentation and information field with particular emphasis on the terms 'information' and 'document'. What influences introduced the concept of 'information' into the library field in the middle of the 20th century? What kind of theoretical orientation have dominated the field, and how are these orientations linked to epistemological assumptions? What is the implication of the recent influence of socially oriented epistemologies for such basic concepts in IS as 'information' and 'document'? The article explores these problems and advocates an approach with emphasis on documents and on the concept 'memory institution' as generic term for the central object of study

- 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
- The concept of information as we use it in everyday English, in the sense of knowledge communicated, plays a central role in contemporary society. The development and widespread use of computer networks since the end of World War II, and the emergence of information science as a discipline in the 1950s, are evidence of this focus. Although knowledge and its communication are basic phenomena of every human society, it is the rise of information technology and its global impacts that characterize ours as an information society. It is commonplace to consider information as a basic condition for economic development together with capital, labor, and raw material; but what makes information especially significant at present is its digital nature. The impact of information technology an the natural and social sciences in particular has made this everyday notion a highly controversial concept. Claude Shannon's (1948) "A Mathematical Theory of Communication" is a landmark work, referring to the common use of information with its semantic and pragmatic dimensions, while at the same time redefining the concept within an engineering framework. The fact that the concept of knowledge communication has been designated by the word information seems, prima facie, a linguistic happenstance. For a science like information science (IS), it is of course important how fundamental terms are defined; and in IS, as in other fields, the question of how to define information is often raised. This chapter is an attempt to review the status of the concept of information in IS, with reference also to interdisciplinary trends. In scientific discourse, theoretical concepts are not true or false elements or glimpses of some element of reality; rather, they are constructions designed to do a job in the best possible way. Different conceptions of fundamental terms like information are thus more or less fruitful, depending an the theories (and in the end, the practical actions) they are expected to support. In the opening section, we discuss the problem of defining terms from the perspective of the philosophy of science. The history of a word provides us with anecdotes that are tangential to the concept itself. But in our case, the use of the word information points to a specific perspective from which the concept of knowledge communication has been defined. This perspective includes such characteristics as novelty and relevante; i.e., it refers to the process of knowledge transformation, and particularly to selection and interpretation within a specific context. The discussion leads to the questions of why and when this meaning was designated with the word information. We will explore this history, and we believe that our results may help readers better understand the complexity of the concept with regard to its scientific definitions.
