Abstract
A theoretical and conceptual approach to the development of the information organization and retrieval is made in an automatic environment by means of the automatic indexing and classification of the information as processes prior to information retrieval. The evolution experienced by the systems of organization of information and knowledge is analysed by taxonomies, thesaurus and Topic Maps toward more complex structures, such as ontologies. Some metadata schemes created for the description of the information in the web, as well as the components and technologies that integrate the theoretical model of the web semantics, are examined. Finally, the constructive stratum model that will guarantee the functioning of its entire infrastructure is explained
