The objective of our co-operation is to investigate effective and efficient methods for managing large collections of structured documents (e. g., XML, SGML, HTML). We will investigate representation and querying techniques combining content and structural knowledge to focus the retrieval to document parts that constitute best entry points to the document structure, from which users can browse to access relevant information.
