Title: KNOWLEDGE EXTRACTION METHOD AND SYSTEM
Abstract:
The knowledge extraction method and system of the present invention obtains an initial sentence group comprising one or more sentences, then compares the initial sentence group length and the desired length, and according to results of comparison, determines which initial sentence group needs to be expanded and performs knowledge extraction. The sentence group is constituted by coherent sentences, thus the sentence group itself has good logical consistency; accordingly, a final sentence group obtained by means of expanding the initial sentence group would also have good logical consistency. Thus the present invention overcomes the defect in the prior art of extracted knowledge information lacking logical consistency.
