- Abstract
- Until very recently, classification theory was held to be nothing but an expressed or unconscious knowledge framed in intuitively given reasons for the subdivision and arrangement of any universe. Today, after clarification of the elements of classification systems as well as the basis of concept relationshios it is possible to apply a number of principles in the evaluation of existing systems as well as in the construction of new ones and by this achieving relatively predictable and repeatable results

- Abstract
- This critical analysis of the BSO draft covers its main structural characteristics from the standpoint of its convenient utilisation, style, terminology, notation, polygraphic making. The analysis concludes that individual shortcomings inherent to the scheme don't exclude its positive evaluation on the whole as a more perfect scheme compared to the Library of Congree Classification and Colon Classification

- Abstract
- Different kinds of syntactic tools of information languages (IL) in use, considered as meaning-distinguished tools, are described as simplified forms of some initial IL grammar tools called 'standard phrases' which are n-place relational predicates of a special kind. A quantitative evaluation is attempted of the effects which the idiosyncracies of the syntactic tools of IL's have on their semantic power

- Abstract
- The common view of the 'aboutness' of documents is that the index entries (or classifications) assigned to documents represent or indicate in some way the total contents of documents; indexing and classifying are seen as processes involving the 'summerization' of the texts of documents. In this paper an alternative concept of 'aboutness' is proposed based on an analysis of the linguistic organization of texts, which is felt to be more appropriate in many indexing environments (particularly in non-specialized libraries and information services) and which has implications for the evaluation of the effectiveness of indexing systems

- Abstract
- Um eine facettenartige Bedeutungsanalyse von Aussagen nach universellen Aspekten zu ermöglichen, wird eine allgemeine Standard-Aussageform vorgeschlagen, die aus folgender Begriffskette besteht: A: Antrieb, Auslöser, Motivation; Z: Ziel; M: Methode; S: System, Substrat; E: Ergebnis, Effekt, Erfahrung, Entscheidung; H: Hintergrund, die auch durch die geläufigen Fragepronomen: warum, wozu, was, wie, wovon angesprochen werden. Es wird gezeigt, wie diese, als 'Semoperatoren' bezeichneten Aussageelemente bei der klassifikatorischen Analyse allgemein und mit Bezug auf die Physik verwenden werden können

- In der Theorie des Schlagwortkatalogs wurden bisher keine Untersuchungen über die spezifischen Eigenheiten eines Faches, seiner Terminologie und die Informationsbedürfnisse seiner Benutzer durchgeführt In dieser Arbeit wird der Versuch einer solchen Untersuchung für das Fach Mathematik unternommen. Neben einer genauen Analyse der Fachterminologie steht die Verknüpfung der verbalen Indexierung mit einer vorhandenen Fachklassifikation - dem Klassifikationsschema der American Mathematical Society - unter Ausnutzung von Fremddaten im Mittelpunkt dieser Untersuchung. Auf diesem Wege können sowohl Qualität als auch Konsistenz der Verschlagwortung gesteigert werden. Es werden praktische Anwendungsmög/ichkeiten abgeleitet.

- Abstract
- Although it is widely accepted that indexing and cataloging are central to the document and reference retrieval process, there is as yet little unamity on the issue of how these operations ought to be carried out. Since indexing is a decision-making process, decision theory and utility theory have been proposed as a possible theoretical framework within which to formulate decision rules for indexing. These decision rules may be interpreted operationally as guides to th thought processes appropriate to the making of sound indexing decisions. Ond such thought process involves "gedanken experimentation", in which the indexer is led to an indexing decision by performing suitable thought experiments. This approach to indexing, in addition to providing a theoretical basis for what the indexer does, lends itself to various training schemes for the education of indexers, to the provision of graphic aids to indexing, and to the evaluation of indexing performance. There are also ramifications for automatic indexing.
