We evaluated the indexing process, to identify the conceptions of subject analysis used in the procedures adopted by catalogers in university libraries. It was concluded that more attention should be given to adoption of approaches content-oriented and requirementsoriented conceptions of subject analysis and use of indexing language compatible with the needs of representation and information of indexers and users of collective catalogues of academic libraries.

The use of indexing language in university libraries collective catalogs and the socio-cognitive context of indexing and users were evaluated. The methodology consisted of a diagnostic study elaboration of the functioning and treatment procedures of the indexing information from nine libraries of the UNESP Network, representing the Civil Engineering, Pedagogy and Dentistry areas from a data collection using the Verbal Protocol introspective technique in the Individual and Group forms. The study conducted a reflection upon the statements issued by the seventy-two participating individuals whose the results revealed unsatisfactory results about the use of the Subject Headings List of the BIBLIODATA Network, indexing language utilizing by the UNESP Libraries Network, Brazil, in the representation and in the information retrieval process in the ATHENA catalog, about the sequent aspects of the language: lack of specialized vocabulary as well as updated; lack of remissives and of specific headings, and others. We have concluded that the adequate use of indexing languages of specialized scientific areas becomes by means of evaluation as to updating, specificity and compatibility in order to meet the needs of indexing and information retrieval.

Avaliou-se o uso de linguagem documentária alfabética de catálogos coletivos, na perspectiva das bibliotecas universitárias e no contexto sociocognitivo dos indexadores e dos usuários. Concluiu-se que o uso adequado de linguagens documentárias de áreas científicas especializadas faz-se por meio da avaliação quanto à atualização, especificidade e compatibilidade para atender às necessidades de indexação e recuperação da informação.

We evaluated study of the indexing process in the cataloging at university libraries, using a socio-cognitive approach to analyze procedures, difficulties and perceptions of librarians, users, and managers. The methodology consisted of the Individual and Group Verbal Protocols applied in university libraries. The results were the absence of procedures for book subject analysis and representation, incompatibility of indexing language, and problems of subject retrieval from the catalog. We have concluded that is tendency of catalogs to act as databases. Therefore, the cataloguer should present a posture of commitment similar to that of an indexer who works in the production of these bases.

The documentary representation in indexing is carried out, at first, in the analysis of subjects to establish the intrinsic and extrinsic aboutness, and then, in the translation stage using the documentary language. The representation by concepts for determining the intrinsic aboutness during the subject analysis is shown by the Documentary Reading Model for indexing of scientific texts and books, Therefore, it was carried out a search on documentary reading for cataloguers for indexing books in academic libraries. A research on catalogers’ documentary reading for indexing books was carried out in nine university libraries. The application of the introspective technique of Individual Verbal Protocol with the catalogers allowed an analysis of subject cataloguing procedures, which made it possible to verify the textual structure parts of a book, as well as to locate the terms identified and selected. The results led to an adaptation of the Documentary Reading Model to book indexing.

The indexing process aims to represent synthetically the informational content of documents by a set of terms whose meanings indicate the themes or subjects treated by them. With the emergence of the Web, research in automatic indexing received major boost with the necessity of retrieving documents from this huge collection. The traditional indexing languages, used to translate the thematic content of documents in standardized terms, always proved efficient in manual indexing. Ontologies open new perspectives for research in automatic indexing, offering a computer-process able language restricted to a particular domain. The use of ontologies in the automatic indexing process allows using a specific domain language and a logical and conceptual framework to make inferences, and whose relations allow an expansion of the terms extracted directly from the text of the document. This paper presents techniques for the construction and use of ontologies in the automatic indexing process. We conclude that the use of ontologies in the indexing process allows to add not only new feature to the indexing process, but also allows us to think in new and advanced features in an information retrieval system.
