METHOD AND APPARATUS FOR ANALYZING TECHNOLOGICAL CONVERGENCE TREND

摘要

Disclosed is a method for analyzing technological convergence trend. According to an embodiment of the present invention, the method comprises the steps of: collecting bibliographic information on patents filed during the predetermined period; generating a plurality of periodical citation matrixes for displaying the number of mutual forward citation between art fields for each period by using the collected bibliographic information; generating a plurality of periodical technological-convergence maps for displaying the art fields which are converged for each period by using periodical cut-off value after determining the periodical cut-off value with respect to the number of forward citation in the periodical citation matrixes, respectively; and analyzing technological convergence trend based on the periodical technological-convergence maps.
