Abstract
The effort around EXTIRP 2004 focused on the heterogeneity of XML document collections. The subcollections of the heterogeneous track (het-track) did not offer us a suitable testbed, but we successfully applied methods independent of any document type to the original INEX test collection. By closing our eyes to the element names defined in the DTD, we created comparable runs and discovered improvement in the results. This was anticipated evidence for our hypothesis that we do not need to know the element names when indexing the collection or when returning full-text answers to the Content-Only type queries. Some problematic areas were also identified. One of them is score combination which enables us to combine elements of any size into one ranked list of results given that we have the relevance scores of the leaf-level elements. However, finding a suitable score combination method remains part of our future work.
