The World Wide Web (WWW) is currently one of the most important electronic information sources. However, its query interfaces and the provided reasoning services are rather limited. Ontobroker consists of a number of languages and tools that enhance query access and inference service of the WWW. The technique is based on the use of ontologies. Ontologies are applied to annotate web documents and to provide query access and inference service that deal with the semantics of the presented information. In consequence, intelligent brokering services for web documents can be achieved without requiring to change the semiformal nature of web documents.
