Abstract

In this paper, we present a new XML retrieval system prototype employing structural indices and a tf * idf weighting modification. We test retrieval methods that a) emphasize the tf part in weighting and b) allow overlap in run results to different degrees. It seems that increasing the overlap percentage leads to a better performance. Emphasizing the tf part enables us to increase exhaustiveness of the returned results.
