abstract = "Global query expansion techniques have long been
proposed as a solution to overcome the problem of term
mismatch between a query and its relevant documents.
This paper describes a method which automatically
tackles the problems of how to find the best terms for
the expansion of a particular query and secondly, how
to weight these terms for use with the original query.
Genetic Programming is used to evolve schemes for term
selection using global (collection-wide) co-occurrence
measures. The schemes evolved are also used to weight
the term in the expanded query as they are a measure of
the term's importance in relation to the query. As a
result, the genetic program has to learn a suitable
scheme for identifying the best correlates for the
query concept and also a scheme that correctly weights
these in relation to each other. These schemes are
tested on standard test collections and show a
significant increase in performance on the training
data but only modest improvement on the collections
that are not included in training.",
