Abstract

In this paper a model for understanding the concept of information is presented and how the processes of externalization and perception of information by human beings could be understood. This model is different from the standard information theoretic model. It combines the understanding of cognitive information processing as an act of information generation from sense impressions with communication theoretic considerations. This approach can be of value for any system that is regarded as a knowledge system with an in-built ordering structure. As an application some consequences will be drawn for the design of information systems which claims to handle information itself (e.g. multimedia information systems) instead of giving references to bibliographic entities

Abstract

Since the introduction of Regeln fur den Schlagwortkatalog (RSWK - Subject Cataloguing Rules) and the arrival of online public catalogues, librarians might ask whether number building is essential or whether the same result could be achieved with Boolean operators. Descriptive categories could be prepared, with word or phrase inversion, as a retrieval system component. The role of syntactic indexing in online retrieval and consequences for service interface ...

Abstract

Librarians in West Germany have thesauri for subject cataloguing through the use of Regeln fur den Schlagwortkatalog (RSWK - Subject Cataloguing Rules) with the Schlagwortnormdatei (SWD - Standard Keyword Data File). There is controversy over the terminological properties of standard keyword data files, over whether SWD is universal and whether inductive vocabulary construction is successful here. Some RSWK chain components have no separate semantic isentity and, although SWD has several aids for definition precision, semantic structures are not fully expressed. At present cooperative cataloguing partners using RSWK should use SWD with it as a starting point and think about possible improvements. RSWK with SWD is at present unsuitable for personal computers
