METHOD FOR INVESTIGATING CITATION RELATIONS USING SPANNING TREE

摘要

A citation relationship search method using a minimum spanning tree showing a citation relationship of a patent in three dimensions with perspective and angle. The citation relationship information of a plurality of technical document data and citation relationship information input from the server And a conversion system for converting a citation relationship into a citation relationship, wherein the conversion system requests the server for citation relationship investigation for a specific technical document, and the conversion system converts citation relationship information of the technical document inspected and sent by the server. Receiving, the transformation system tracking the minimum spanning tree using the received citation relationship information, and the transformation system two dimensions of each node of the tracked minimum spanning tree in the x-axis and y-axis planes. And the transform system outputs a z-axis at each node of the minimum spanning tree. This stage, the conversion system for computing the coordinates of the statistical information includes the step of outputting a 3-D relationship is also incorporated with a perspective angle and a combination of the x, y, z-axis value.;By using the above-described citation relationship investigation method using the spanning tree, the citation relationship between patents can be easily identified by showing the citation relationship of the patent in three dimensions having a perspective and an angle.; Spanning Tree, Citations, Citations, Citations, Station
