Mixture Models, Overlap, and Structural Hints in XML Element Retrieval, however, useful for achieving high initial precision. Finally, we provide a detailed analysis of the characteristics of one of our runs. Based on this analysis we argue that a more explicit definition of the INEX retrieval tasks is needed.

Recently, an INEX working group identified the minimal set of requirements for a suitable query language for future workshops. From this analysis a new IR query language NEXI is introduced for upcoming workshops.

An Algebra for Structured Queries in?Bayesian?Networksed information queries and can be used within our Bayesian Network framework. With this algebra, the representation of the information demand is independent from the structured query language. It allows us to answer both vague and strict structured queries.

Contributions to Management Scienceon in the development of XML retrieval systems. These systems exploit the logical structure of documents, which is explicitly represented by the XML markup: instead of whole documents, only components thereof (the so-called XML elements) are retrieved in response to a user query. This means that an
