abstract = "Modern Web search engines use different strategies to
improve the overall quality of their document rankings.
Usually the strategy adopted involves the combination
of multiple sources of relevance into a single ranking.
This work proposes the use of evolutionary techniques
to derive good evidence combination functions using
three different sources of evidence of relevance: the
textual content of documents, the reputation of
documents extracted from the connectivity information
available in the processed collection and the anchor
text concatenation. The combination functions
discovered by our evolutionary strategies were tested
using a collection containing 368 queries extracted
from a real nation-wide search engine query log with
over 12 million documents. The experiments performed
indicate that our proposal is an effective and
practical alternative for combining sources of evidence
into a single ranking. We also show that different
types of queries submitted to a search engine can
require different combination functions and that our
proposal is useful for coping with such differences.",
