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.",
