Ontologies as Background Knowledge to Explore Document Collections
This paper introduces a new approach to provide users with solutions to explore a domain via an information space. A key point in our approach is that information searching and exploring takes place in a domaindependent semantic context. A given context is described through its vocabulary organised along hierarchies that structure the information space. These hierarchies are simplified views on a more complex domain specific ontology, that form a shared and coherent background knowledge representation. So the system benefits from the combination of two innovations that make the exploration of the document space more effective. First, hierarchies (extracted from the ontology) provide with a language and synthetic representation to be explored by the users to express their information need. Additionally, a visual interface presents answers to their queries using multi-dimensional analysis and a global visualisation of document collections. At both stages, ontology is the key structure t...
