“…Comparing the results presented here to our INEX 2005 results (Dopichaj, 2006), note that the implementation used for the runs we submitted to INEX differs from the version described in this paper: The scores are not updated independently, so the patterns applied later receive the scores already updated by earlier patterns, which may lead to unintended interactions.…”

Improving Content-Oriented XML Retrieval by Applying Structural Patterns

XML is the perfect format for storing (mostly) textual documents in a knowledge management system; its flexibility enables users to store both highly structured data and free text in the same document. For knowledge management, it is important to be able to search the free-text parts effectively; users need to find the information that helps them solve their problem without having to wade through much information that is not relevant for their problem. Content-oriented XML retrieval addresses this challenge: In contrast to traditional information retrieval, documents are not considered atomic units, that is, elements such as sections or paragraphs can be returned. One implication of this is that results can overlap (for example a paragraph and the surrounding section). Although overlapping results are undesirable in the final retrieval result as presented to the user, they can help to improve the quality of the final result: We take advantage of overlaps by applying patterns to small subtrees of the retrieval result (result contexts); matching patterns adjust the retrieval status values of the involved node in order to promote the best results. We demonstrate on the INEX 2005 test collection that this postprocessing can lead to a significant improvement in retrieval quality.

“…To determine whether our new method can improve result quality, we participated in the INEX 2005 workshop Dopichaj (2006). The INEX (Initiative for the Evaluation of XML Retrieval) workshop (Fuhr et al, 2005) is a yearly event for evaluating the effectiveness of XML retrieval systems.…”
