摘要:
An exemplary embodiment of the present techniques extracts concepts and relationships from a text. Concepts may be generated from the text using singular value decomposition, and ranked based on a term weight and a distance metric. The concepts that are ranked above a particular threshold may be iteratively extracted, and the concepts may be merged to form larger concepts until the generation of concepts has stabilized. Relationships may be generated based on the concepts using singular value decomposition, then ranked based on various metrics. The relationships that are ranked above a particular threshold may be extracted.
