  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.",
