Proteus: a concept browsing interface towards conventional Information Retrieval Systems

In the access to the unstructured information, the representation of the relevant concepts is a fundamental issue for the sharing of the knowledge between indexers and users. The browsing of the concepts can play an important role in the user interface. We present an implementation of an interface that will give the possibility of interacting with a conceptual structure of the documents, and of making a graphical navigation on the thesauri available on the different fields.
