SYSTEM FOR VISUALIZATION OF PATENT INFORMATION BY FORMING THE KEYWORD BASED SEMANTIC NETWORK AND METHOD THEREFOR

摘要

PURPOSE: A patent information visualization system through a keyword semantic network configuration and a method thereof are provided to arrange a semantic network based on a time axis by building keywords of the semantic network. CONSTITUTION: A semantic network composing unit(300) sets a patent document group including the rest of keywords except for a common keyword as the lower node. A patent map constructing unit(400) searches patent application date of a patent document and the frequency included in patent document groups through the semantic network configuration unit about each node setting. The patent map constructing unit sets the frequency value and patent application date value as an arbitrary xy axis. The patent map constructing unit constructs a patent map by indicating the semantic network on a coordinate plane due to the xy value of each node.
