A framework for BM25F-based XML retrieval
Kelly Y. Itakura, Charles L. A. Clarke · 2010
We evaluate a framework for BM25F-based XML element retrieval. The framework gathers contextual information associated with each XML element into an associated field, which we call a characteristic field. The contents of the element and the contents of the characteristic field are then treated as distinct fields for BM25F weighting purposes. Evidence supporting this framework is drawn from both our own experiments and experiments reported in related work.
