TL;DR: A set of programs have been developed to construct a classaurus using as input, subject headings formulated according to POPSI language which are enriched with certain codes to denote the different Elementary Categories, their Species, Parts, Special Modifiers and other Common Modifiers of different kinds.
Abstract: Classaurus is a faceted hierarchic scheme of terms with vocabulary control features. It is a system of terms having separate hierarchic schedules of the Elementary Categories: Discipline, Entity, Property, and Action, together with their respective Species/Types, Parts and Special Modifiers. Also there are separate schedules for the Common Modifiers: Form, Time, Environment, and Place. Each of the terms in these hierarchic schedules is enriched with synonyms, quasi synonyms etc. The hierarchic schedules constituting the systematic part is supplemented by an alphabetical index of chain entries. Classaurus is used in the formulation of subject headings in general, and in particular, subject headings according to the Postulate based Permuted Subject Indexing (POPSI) language. For the construction of classaurus the POPSI language itself provides guidelines. A set of programs have been developed to construct a classaurus using as input, subject headings formulated according to POPSI language which are enriched with certain codes to denote the different Elementary Categories, their Species, Parts, Special Modifiers and other Common Modifiers of different kinds. The resulting classaurus has hierarchic schedules but terms in an array are arranged only alphabetically. The hierarchic schedules constitute the Systematic part of the classaurus. The system generates an alphabetic Index Part to the Systematic Part, in which for each term its broader terms are kept to its right hand side successively along with a code to denote the schedule to which the term belongs. To find out the position of a term in the Systematic Part, the whole entry for the term in the Alphabetic Part is taken and the sequence of the terms in it is reversed. Using the code for the schedule in the entry, the appropriate hierarchic schedule is selected. The schedule is then searched using the broader terms successively as keys until the term in question is reached, wherein all the hierarchically related terms could be found, including synonyms, quasi-synonyms etc. Both the Systematic Part and the Alphabetical Index Part are printed out for manual reference and also kept as direct access files for ondashline access and ondashth-spot updating and building up of the classaurus while inputting new subject headings formulated for this purpose.

TL;DR: A set of techniques and tools is presented regarding mathematical, statistical, and neural fields that, when linked together, enable semiautomatically building domain representations and storing them in a thesaurus structure of software components.
Abstract: Domain analysis was first used 15 years ago as one of the most important techniques for software reuse. Even today, new techniques appear every year, and different authors propose different domain representation structures to represent and store all the different software components and the relationships among them. These relationships among components are the kernel of the domain semantics. In this report, a set of techniques and tools is presented regarding mathematical, statistical, and neural fields that, when linked together, enable semiautomatically building domain representations and storing them in a thesaurus structure of software components. Thesaurus structures, widely used in information science, are presented as the domain-modeling key concept, due to their higher automation possibilities compared with previous structures. New metrics to evaluate the quality, consistency, and completeness of the domain model obtained through this technique are also presented.

TL;DR: An introduction to the new topic map standard (ISO/IEC 13250) is provided with particular reference to the domain of encyclopaedia publishing, and the relationship between topic maps and the W3C recommendation Resource Description Framework (RDF) is discussed.
Abstract: This article provides an introduction to the new topic map standard (ISO/IEC 13250) with particular reference to the domain of encyclopaedia publishing, and discusses the relationship between topic maps and the W3C recommendation Resource Description Framework (RDF). It is based on the author’s participation in the development of the topic map standard (representing Norway in SC34, the ISO committee responsible for SGML and related standards), and two years’ collaboration with leading reference works publishers in Norway, Denmark, Sweden, Poland and Germany.

01 Dec 2000TL;DR: This paper propose a modelo mais adequado for a ciencia da informacao o segundo, em decorrencia de sua relacao com a sociedade, do seu carater interdisciplinar, dinâmico, objetivo e recursivo.
Abstract: O trabalho tem por objetivo discutir as caracteristicas da ciencia da informacao. Primeiramente, o objeto da ciencia da informacao e tratado segundo as perspectivas de Ranganathan, Borko, Werzig, Urdaneta, Hwang e Le Coadic. Num segundo momento, verificam-se os modos de producao da ciencia classica, o novo modo de producao do conhecimento e a pertinencia de se aplicarem esses modelos a ciencia da informacao. Propoe-se como modelo mais adequado para a ciencia da informacao o segundo, em decorrencia de sua relacao com a sociedade, do seu carater interdisciplinar, dinâmico, objetivo e recursivo.
