We explore the use of state of the art query expansion techniques combined with a new family of ranking functions which can take into account some semantic structure in the query. This structure is extracted from WordNet similarity measures. Our approach produces improvements over the baseline and over query expansion methods for a number of performance measures including GMAP.
