  abstract =     "presents an evaluation of evolved term-weighting
                 schemes on short, medium and long TREC queries. A
                 previously evolved global (collection-wide)
                 term-weighting scheme is evaluated on unseen TREC data
                 and is shown to increase mean average precision over
                 idf. A local (within-document) evolved term-weighting
                 scheme is presented which is dependent on the best
                 performing global scheme. The full evolved scheme (i.e.
                 the combined local and global scheme) is compared to
                 both the BM25 scheme and the Pivoted Normalisation
                 scheme. Our results show that the local evolved
                 solution does not perform well on some collections due
                 to its document normalisation properties and we
                 conclude that Okapi-tf can be tuned to interact
                 effectively with the evolved global weighting scheme
                 presented and increase mean average precision over the
                 standard BM25 scheme.",
