Abstract:
In this paper, we address the use of data together with metadata to improve information access to XML document collections. We first emphasize the possibility to associate meta-information to parts of XML documents, and not only entire documents. This is accordingly to the fact that XML elements are considered as retrieval units. We, then, propose to explicitly search the desired information using a query language that is composed of XML search and metadata search. We focus our ideas in two types of metadata: Dublin Core and ontologies.
