Abstract
The advent of technologies in information retrieval driven by users’ requests calls for an effort to conceive and develop semantic-based applications. In recent years the semantic web gave place for a new generation of search query engines that rely on the semantic of the documents expressed by metadata. In this paper we present a knowledge-based approach to visualizing and navigating through conference video-recordings. This approach is based on a confer- ence ontology that models the information conveyed within a con- ference life cycle.
