  abstract =     "Traditional ad hoc retrieval models do not take into
                 account the closeness or proximity of terms. Document
                 scores in these models are primarily based on the
                 occurrences or non-occurrences of query-terms
                 considered independently of each other. Intuitively,
                 documents in which query-terms occur closer together
                 should be ranked higher than documents in which the
                 query-terms appear far apart.

                 This paper outlines several term-term proximity
                 measures and develops an intuitive framework in which
                 they can be used to fully model the proximity of all
                 query-terms for a particular topic. As useful proximity
                 functions may be constructed from many proximity
                 measures, we use a learning approach to combine
                 proximity measures to develop a useful proximity
                 function in the framework. An evaluation of the best
                 proximity functions show that there is a significant
                 improvement over the baseline ad hoc retrieval model
                 and over other more recent methods that employ the use
                 of single proximity measures.",
