XML is a representation of data which may require huge amounts of storage space and query processing time. Summarized representations of XML data provide succinct information which can be directly queried, either when fast yet approximate answers are sufficient, or when the actual dataset is not available. In this work we show which kinds of XQuery expressions admit a partial answer by using association rules extracted from XML datasets. Such partial information provide intensional answers to queries formulated as XQuery expressions.
