Abstract

The Knowledge Organization Systems, specifically the Universal Decimal Classification, aims to increase the quality of the relationships of the concepts of a domain, having potential use in on-line recovery systems. The purpose of this article is to present methodologies used with the Universal Classification linked to a thesaurus, in order to improve information retrieval. The methodological procedures used classify the research as descriptive, qualitative and exploratory, using a literature review. To select the sources of consultation, the main databases in the area of Information Science were used, without time frame, being chosen only the works that addressed the use of the Universal Decimal Classification to improve the retrieval of information in the web environment. The results revealed several aspects related to the context of this theme, the theoretical bases and conceptual foundations, identifying old and recent studies, which made it possible to point out future practices and perspectives regarding the use of bibliographic classification systems. With the mapping of the literature, it was concluded that the potential of the Universal Classification is in correspondence with the terms of a related thesaurus. It was noticed that the theme has still been little explored, with a predominance of articles published in a foreign language, which is why it is necessary to pay more attention to the potential of this classification system for the information retrieval on the web.
