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

It is argued that concepts are the building blocks of knowledge organizing systems (KOS). Objections to this view are considered and answers are provided. By implication the theory of concepts constitutes the foundation for knowledge organization (KO). The theory of concepts is understood as related to and derived from theories of knowledge. Different theories of knowledge such as empiricism, rationalism, historicism and pragmatism imply different theories of concepts. Such different epistemologies and their associated theories of concepts represent different methodological ideals which probably compete in all knowledge domains. Different approaches to KO are also in fundamental ways associated with different theories of concepts. The paper holds that the historicist and pragmatic theory of concept should be considered most valuable. By implication is it is necessary to know about competing theories in the fields being organized. A further implication of the pragmatic view is that the construction of a KOS must be understood as a way of participating in the discourses in the domain that is being represented.

Abstract

Thanks to Professor Eric Scerri for engaging in debate in this journal (Scerri 2011) by replying to my review (Hjørland 2008a) of his book (Scerri 2007). One of my points has been that we in our community (Knowledge Organization, KO / Library and Information Science, LIS) have been too isolated from broader academic fields related to classification and the organization of knowledge. The present debate is a step towards reversing this situation. Bezug zu: Scerri, E.R.: The periodic table: its story and its significance.

Abstract

The notion "theory" is a neglected concept in the field of information science and knowledge organization (KO) as well as generally in philosophy and in many other fields, although there are exceptions from this general neglect (e.g., the so-called "theory theory" in cognitive psychology). This article introduces different conceptions of "theory" and argues that a theory is a statement or a conception, which is considered open to be questioned and which is connected with background assumptions. Theories form interconnected systems of grand, middle rank and micro theories and actions, practices and artifacts are theory-laden. The concept of knowledge organization system (KOS) is briefly introduced and discussed. A theory is a form of KOS and theories are the point of departure of any KOS. It is generally understood in KO that concepts are the units of KOSs, but the theory-dependence of concepts brings theories to the forefront in analyzing concepts and KOSs. The study of theories should therefore be given a high priority within KO concerning the construction and evaluation of KOSs.
