Patent ID: 8370128

Claim:
A method of developing rules for text processing comprising: identifying a semantic relation involving at least two named entities, each named entity being represented in the semantic relation by its class; providing a set of example instances, each example instance consisting of a combination of named entities which satisfy the semantic relation; retrieving text strings from text, each of the retrieved strings including at least two of the named entities of one of the example instances in the set, the text strings being retrieved regardless of any lexico-syntactic relationship involving the named entities; extracting, from the retrieved text strings, syntactic patterns, each syntactic pattern involving at least two of the named entities of one of the example instances in the respective retrieved text string; generating generalized rules for text processing based on the extracted syntactic patterns, the rules being of a form for identifying candidate instances of the semantic relation in text; and wherein the retrieving of text strings, extracting of syntactic patterns, and generating of rules are computer implemented.
