This paper presents conceptual navigation and NavCon, an architecture that implements this navigation in World Wide Web pages. NavCon architecture makes use of ontology as metadata to contextualise user's search for information. Conceptual navigation is a technique to browse websites within a context. Context filters relevant retrieved information, and it drives user's navigation through paths that meet his needs. Based on ontologies, NavCon automatically inserts conceptual links in web pages. These links permit the users to access a graph representing concepts and their relationships. Browsing this graph, it is possible to reach documents associated with user's desired ontology concept.
