Scoring at any level in the document is useful when the size of the expected result is not fixed and when the content of each result is conditional. Large XML documents in particular would benefit from functionality like this. Regards, Miro Lehtonen Department of Computer Science University of Helsinki Use Case: Query Combining Score and Structure with a Conditional Return Description ----------- Find all books with parts about usability testing. This query finds all the books that contains parts about usability testing. If a part does not concern usability testing, e.g. it does not contain the phrase "usability testing", the part element is not included in the result. * Operands: "usability testing" * Functionality: phrase query, implementation-defined scoring, filters on scores, conditional query * Context: books//content * Return: books/book * Comments: This use case is almost like 16.2.5 with scores, but the set of conditionally returned elements (content) is fixed. Each part element is returned either as a whole or as a summarized version only containing the title element. This query type is especially useful when dealing with large, volume-sized XML documents consisting of several journals each with several articles. The expected results include the full-text of the most relevant articles only, and the other articles are shortened. The operands can be words instead of phrases. Expected result --------------- <book number="1"> <metadata> ... </metadata> <content> <introduction> ... </introduction> <part number="1"> <title>Expert Reviews</title> </part> <part number="2"> <chapter> <title>Usability Testing</title> <p>Once the problems identified by expert reviews have been corrected, it is time to conduct some tests of the site with your unique audience or audiences by conducting usability testing.</p> <p>Users are asked to complete tasks which measure the success of the information architecture and navigational elements of the site.</p> <p>Then changes are made to improve service to users.</p> </chapter> </part> </content> </book>
