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
