Web semántica y ontologías en el procesamiento de la información documental

The lack of a well defined model of information representation on the web has produced several problems related to processing information. In an effort to resolve these problems, the W3C has proposed the semantic web project. This new scenario offers both possibilities and difficulties for the future. Special attention is given to ontologies, fundamental tools for the representation of knowledge on the semantic web. Finally, the role of library and information professionals is considered in this new context.
