Abstract

Some theory of classification underlies most practical activities, whether individual or social. It is involved in most attempt to understand the structure or reality on a metaphysical level and it is presupposed in the formulation of scientific laws. The logical and meterial principles of classification are covered as well as various general problems and criteria of classification. Differing classification principles in particular domains such as the natural sciences and medicine and in information are discussed as well as the place and role of classification in scientific method, its relation to and dependence on theory, scientific nomenclature and the philosophical issues through the heritage of Plato and Aristotle

Abstract

Modern education is concerned with helping children to understand society and a multi-media documentation centre in each school is a necessary teachign aid. Beginning with static book collections, documentation centres should expand into dynamic information sources containing all media and concentrating on current material. Provincial libraries will often provide this service for an egreed fee. Most centres have classified catalogues based upon the Dutch SISO classification system for public libraries. Essential to the setting up and running of a documentation centre is the goodwill and appreciation of teachinf staff who must participate in every aspect of it

Abstract

The paper deals with procedures and problems arising when computers are used as tools in the production of indexes. The following steps of the procedure are explained and studied: 1) Correction of machine-readable records; 2) Production of index entries. Here, various methods and forms (KWIC, KWOC, rotation method) and dictionary use are described and discussed, and information about their advantages and disadvantages is given; 3) Sorting and cumulation of index entries; 4) Output and setting, output feasibilities are detailed. Emphasis is also laid on the problems arising from the non-satisfactory links of the processing chain: data recording, limited fonts, and choice of index terms.

Abstract

This paper examines the implications of the findings of evaluative tests regarding the retrieval performance of natural language in various subject fields. It suggests parallel investigations into the structure of natural language, with particular reference to terminology, as used in the different branches of basic science. The criteria for defining the terminological consistency of a subject are formulated and a measure suggested for determining the degree of terminological consistency. The terminological and information structures of specific disciplines such as, chemistry, physics, botany, zoology, and geology; the circumstances in which terms originate; and the efforts made by the international scientific community to standardize the terminology in their respective disciplines - are examined in detail. This investigation shows why and how an artificially created scientific language finds it impossible to keep pace with current developments and thus points to the source of strength of natural language

Abstract

The suggestion that classifications for retrieval should be constructed automatically raises some serious problems concerning the sorts of classification which are required, and the way in which formal classification theories should be exploited, given that a retrieval classification is required for a purpose. These difficulties have not been sufficiently considered, and the paper therefore attempts an analysis of them, though no solution of immediate application can be suggested. Starting with the illustrative proposition that a polythetic, multiple, unordered classification is required in automatic thesaurus construction, this is considered in the context of classification in general, where eight sorts of classification can be distinguished, each covering a range of class definitions and class-finding algorithms. The problem which follows is that since there is generally no natural or best classification of a set of objects as such, the evaluation of alternative classifications requires either formal criteria of goodness of fit, or, if a classification is required for a purpose, a precises statement of that purpose. In any case a substantive theory of classification is needed, which does not exist; and since sufficiently precise specifications of retrieval requirements are also lacking, the only currently available approach to automatic classification experiments for information retrieval is to do enough of them
