This paper proposes the use of ontologies representing domain and linguistic knowledge for guiding natural language (NL) communication on the Web contents. This proposal deals with the problem of obtaining and processing the Web data required to answer users queries. Concepts and communication acts are represented in a conceptual ontology (CO). Domain-restricted linguistic resources are obtained automatically by adapting the general linguistic knowledge to cover the communication acts for a particular domain. The use of domain-restricted grammars and lexicons has proved to be efficient, especially when the user is guided in introducing the sentences. To answer users queries the system fires the appropriate wrappers to extract the data from the Web. The CO provides a unifying framework to represent and process the knowledge obtained from the Web. Following this proposal, a dialogue-system for accessing a set of Web sites on the travelling domain in Spanish has been implemented.
