Generating and using social brains with complimentary semantic brains and indexes

摘要

A method includes determining a plurality of social interactions associated with a plurality of people, generating a social object matrix using the determined social interactions, and generating a social brain by performing Singular Value Decomposition (SVD) on the social object matrix. The method further includes determining text from the social objects of the determined social interactions, generating a term-document matrix (TDM) using the determined text, generating a semantic brain by performing SVD on the TDM, generating an index using the determined text, and performing a query using the social brain, the semantic brain, and the index. The social brain is a singular value representation of the social object matrix and the semantic brain is a singular value representation of the TDM. Each social interaction is a particular person interacting with a particular social object.
