To present the user with the results they are most probably looking for, AQG
uses conceptual clustering to assemble a single page containing the very best hits from each of the most relevant concepts, both from the intranet and the Web.
For example, if a user in a manufacturing company user queries "washer", AQG
uses conceptual clustering to determine if the user is most likely to desire documents on washers as a component for a tap, or on washers as in washing machines.
