PROBLEM TO BE SOLVED: To provide improved search and interface technology that aids in providing results that are more in line with the actual concepts in which a user may be interested and a better user experience.SOLUTION: In a search processing system, a concept network is generated from a set of queries by parsing a plurality of queries into a plurality of units and defining various relationships between the units based in part on patterns of the units that appear together in queries. Units in the concept network that have some similar characteristics are grouped into superunits. For each superunit, there is a corresponding signature that defines the similar characteristic of the group. A query is processed by identifying a plurality of constituent units, determining the superunit membership of some or all of the constituent units, and using that information to formulate a response to the query. |
