Patent ID: 8375033

Claim:
A method for information retrieval, performed by a computer processor ( 115 ), the method comprising the steps of: a. processing a corpus of sentences, wherein said processing comprises the steps of (i) providing a ranking criteria module ( 135 ), containing predefined ranking criteria, and coupled to operate with the computer processor; (ii) retrieving textual documents from a corpus of text documents ( 120 ), wherein said corpus is in operative communication flow with the computer processor; (iii) extracting prominent sentences from said textual documents, using said ranking criteria module; and (iv) updating a database of prominent sentences ( 130 ), coupled to operate with the computer processor; and b. retrieving prominent sentences from said database of prominent sentences, prioritized by said predefined ranking criteria and by user search keywords, wherein said extracting of prominent sentences comprises the step of scoring sentences according to at least one extracted rule; and wherein said extracted rule comprises the steps of: A. retrieving multiple sentences from said corpus of text documents, wherein for each of said retrieved sentences perform the following steps: 1) identifying the structure of said retrieved sentence; 2) identifying a verb pattern in said retrieved sentence, using said identified structure; and 3) scoring said identified verb pattern, using said ranking criteria module: B. summing the score of each uniquely identified verb pattern over all the occurrences of said uniquely identified verb pattern in said corpus, to thereby generate aggregated scores for all of said uniquely identified verb patterns; and C. matching said aggregated scores of said uniquely identified verb patterns with a pre-defined threshold, to thereby generate prominence assigning rules.
