Okapi BM25 scoring of anchor text surrogate documents
has been shown to facilitate effective ranking in navigational
search tasks over web data. We hypothesize that even better
ranking can be achieved in certain important cases, particularly
when anchor scores must be fused with content scores,
by avoiding length normalisation and by reducing the attentuation
of scores associated with high tf . Preliminary
results are presented.
