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 in the WWW. It provides languages to annotate web documents with ontological information, to represent ontologies, and to formulate queries. The tool set of Ontobroker allows us to access information and knowledge from the web and to infer new knowledge with an inference engine based on techniques from logic programming. This article provides several examples that illustrate these languages and tools and the kind of service that is provided. We also discuss the bottlenecks of our approach that stem from the fact that the applicability of Ontobroker requires two time-consuming activities: (1) developing shared ontologies that reflect the consensus of a group of web users and (2) annotating web documents with additional information.
