International projects for reforming and broadening the scope of the current technical guidelines and standards on thesauri are presented. The aims of these projects are to recast the existing standards and guidelines, to adapt them to the new digital environment, and to specify their [...]

Abstract

Since the (re)appearance of ontologies in the late nineties, there is a debate about the relationship between thesauri and ontologies. This article presents a synthesis of this debate, focusing on the use of these tools in the information systems area, which is the best one to compare [...]

Abstract

A practical approach to the development of ontologies from thesauri is presented, using the Methontology methodology, which permits the use of any language developed so far for the implementation of ontologies, as well as semantic web annotations based on these ontologies. This approach [...]

Abstract

Thesauri and other knowledge organization systems have been adapted to the technological environment. Currently, this represents an essential aspect of knowledge organization on the semantic web. After a long period in which thesaurus guidelines and standards were not updated, some [...]

Abstract

The main points of convergence and divergence between controlled indexing languages and ontologies, tools for knowledge organization and information retrieval in the semantic web, are described. Fundamental aspects of ontologies are presented, as well as the basic semantic and structural [...]

Abstract

The number of papers written on ontologies has increased considerably over the last twenty years. This trend can be easily observed by searching words like “ontology” or “thesaurus” in databases. Despite this fact, there hasn’t been a consensus about the significance of [...]

Abstract

News documentation lacks suitable instruments of classification and indexing, the only exception being the Subject Reference System of the International Press Telecommunications Council (IPTC), which is not yet fully developed. The most relevant contributions to classifying and indexing [...]
