Using XML Logical Structure to Retrieve (Multimedia) Objects

This paper investigates the use of the logical structure in XML documents for the retrieval of XML multimedia objects. We study different logical levels and their combinations. Our investigation is carried on a purposebuilt test collection based on the INEX test collection. Our findings are the followings. First, all logical levels allow discriminating between elements contained in different documents, whereas the lower logical levels allow discriminating between elements within a same document. Second, combining the logical levels improve retrieval performance.
