Rich entities for knowledge bases

Abstract:

According to one embodiment, a computer program product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a processor to cause the processor to: identify key concepts in a domain ontology, and define a workload as a set of queries. Terms are extracted from each of the queries, and frequent patterns are detected across the set of queries. Maximal patterns are also identified from the frequent patterns detected, while the key concepts and the maximal patterns are used to create a rich entity. Moreover, identifying the key concepts includes performing centrality analysis of concepts extracted from the domain ontology. Other systems, methods, and computer program products are described in additional embodiments.
