Comparing the Conceptual Graphs Extracted from Patent Claims
Shih-Yao Yang, Von‐Wun Soo · 2008
A patent claim defines the protection of the invention. It is usually very time consuming and laborious to manually conduct analysis on patents in any domain of interest. A maximal common edge subgraph (MCES) is a subgraph consisting of the largest number of edges common between two graphs G and G'. This paper automatically compares conceptual graphs, extracted from patent claims by an NLP parser, using anchored relaxation labeling.
