Abstract: Early research at the end of the 1950s on computerized indexing used statistical methods based on e.g. frequency, probability, clustering, and relevance. In the 1960s interest began to focus on linguistic analysis and natural language processing e.g. morphological, morphosyntactical, syntactical and semantic analysis. Since the 1980s computerized indexing research has widened to include images, graphics and sound. Examples are given of notable systems developed within each line of approach

Abstract

The term information lacks precicion and there is no consensus about its definition because of the differing philosophical theories used as a basis for interpretation e.g. materialism, idealism. Draws on the ideas of Locke, Kant and Piaget to analyse the essential nature of information, concluding that for the purposes of library science, information is best understood as an ideal entity constructed by the individual synthesising his sensory perceptions of the actual world, which is then objectivised resulting in the world of information, part of the wider world but with its own structures, laws and interrelations. This make communication possible

Abstract

There is no generally agreed definition of what constitutes information or information science, but Kuhn's notion of paradigms provides a useful perspective for analysing current theories. If information science is considerd as an 'immature science', i.e. one yet to develop its own paradigm, this links it to the debate about science and technology: many of the activities associated with information science, e.g. organising information for users by creating databases, belong to the domain of technology. On this basis, computer related activities concerned with information can be dissociated from the domain of computer science, thus establishing an independent status for information science

Abstract

The concept of information provokes discussion in many scientific realms, e.g. in physics, the relationship between information and entropy. Information has been associated by communication engineers with the freedom of choosing symbols to construct a message. To confuse matters further, Shannon used entropy as a metaphor in his analysis of statistical behaviour of symbols, but Stonier points out the possibility of a different relationship between information and entropy. The definition of information should ba analogous to the physical definition of energy, the capability of performing work, whereas the the capability of organizing systems corresponds to information. Moreover, it is necessary to distinguish the reality of information on its own from the meaning of information inside each context. One of the most striking contexts are biological systems which rely on sophisticated information processing mechanisms as yet not fully understood
