	abstract = {Based on the document-centric view of XML, we present
the query language XIRQL. Current proposals for XML
query languages lack most IR-related features, which
are weighting and ranking, relevance-oriented search,
datatypes with vague predicates, and semantic
relativism. XIRQL integrates these features by using
ideas from logic-based probabilistic IR models, in
combination with concepts from the database area. For
processing XIRQL queries, a path algebra is presented,
that also serves as a starting point for query
optimization.},
