Claim 10:
11. A computer system for classifying resource description framework (“RDF”) triples, the computer system comprising:
a knowledge base computer system; and
a remote computer system that is in communication with the knowledge base computer system via a data network, wherein:
the knowledge base computer system comprises:
a processor core;
a memory in communication with the processor core, wherein the memory stores software that when executed by the processor core, causes the processor core to:
extract semantic triples from text in a set of domain-specific electronic documents, wherein the extracted semantic triples are represented as subject, predicate and object, such that the subject and the object have a semantic relationship;
identify topics in a domain specific KB, wherein the domain specific KB comprises a plurality of concepts, and memory stores instructions that, when executed by the processor core, cause the processor core to identify the topics by:
for each concept in the domain specific KB, construct a computational cluster_graph around a centroid that is the concept, wherein the computational cluster graph comprises, as vertices, other concepts in the domain specific KB that are related and narrower than the centroid;
compute a score for each of the computational cluster graphs according to a scoring algorithm; and
identify as topic candidates one or more concepts based on the score of the corresponding computational cluster graph; and

store the domain specific KB in the memory such that the concepts in the domain specific KB are identified using unique Hypertext Transfer Protocol (HTTP) Uniform Resource Identifiers (URIs); and

the remote computer system is programmed to access the concepts in the domain specific KB using the URIs for the concepts and to classify RDF triples based on the domain specific KB stored in the knowledge base computer system.
