Laurent Mignet, Mihai Preda, Serge Abiteboul, Bernd Amann, Amlie Marian

We consider the acquisition and maintenance of XML data found on the web. More precisely, we study the problem of discovering XML data on the web, i.e., in a world still dominated by HTML, and...

Application of a Graph Model to Hypertext Querying (2007)

Bernd Amann, Michel Scholl

We present a model for data organized as graphs with typed nodes and edges. Regular expressions over the types of the node and edge labels are used to select walks in the hypertext graph. An outline...
