Abstract

The number of information sources in the Internet is exponentially increasing. As a consequence, for a given query, the set of potentially interesting sites is very high but only very few sites are really relevant. Furthermore, information is highly heterogeneous both in its structure and in its origin. In particular, not only data types are heterogeneous (textual data, images, sounds, etc.), but even the representation of a single data type can differ.
