Abstract—In this paper, we propose a method for accurately retrieving XML elements considering document updates. If doc-ument updates are not handled in a search system, users cannot obtain appropriate search results, which reduces the usefulness of the search system. We apply an incremental

This short position paper discusses the issues arising when the expectations of element retrieval are applied to heterogeneous document collections. One assumption of element retrieval strategies is that it is actually possible for searchers to specify the elements to be retrieved. As collections

XML retrieval, a very active branch of IR, studies the focused retrieval of semi-structured data. Although much progress has been made, especially through the annual INitiative for the Evaluation of XML retrieval (INEX), very little is known about XML element retrieval in action: What do users

the INEX 2005 Interactive Track, mainly focusing on a comparative experiment, in which the baseline system Daffodil/HyREX is compared to a home-grown XML element retrieval system (xmlfind). The xmlfind system provides an interface for an XML information retrieval search engine, using an index

... Institute of the University of Amsterdam. We completely revamped our XML retrieval system, now implemented as a mixture language model on top of a standard search engine. To speed up structural reasoning, we indexed the collection’s structure in a separate database. Our main findings

INEX, the evaluation initiative for content-oriented XML retrieval, has since its establishment defined the relevance of an element according to two graded dimensions, exhaustivity and specificity. The former measures how exhaustively an XML element discusses the topic of request, whereas
