Patent ID: 7158957

Claim:
An information mining method, comprising: extracting multiple key-phrases from unstructured text; obtaining a predetermined number of key-phrases from the multiple key-phrases; generating a layer of template contextual relation map by mapping the predetermined number of key-phrases to a three-dimensional map using a self-organizing map; generating a layer of dynamic information contextual relation map for the received unstructured text by mapping the transformed key-phrases to the three-dimensional map using the self-organizing map; forming phrase clusters for the template contextual relation map; mapping phrases of the information to be classified using the phrase clusters of the generated template contextual relation map; constructing template and dynamic information key-phrase frequency histograms consisting of the frequency of occurrences of key-phrases, respectively, from the generated template contextual relation map and the dynamic information contextual relation map; generating template and dynamic information three-dimensional structured maps from each of corresponding template and dynamic key-phrase frequency histograms; and extracting desired information by mapping the dynamic information three-dimensional structured map on to the template three-dimensional structured map.
