基于证据推理的核心技术识别方法研究
On Recognition of the Core Technology Using Evidential Reasoning
摘要
Abstract
Based on an analysis of the original data of certain field collected from The US Patent and Trademark Office ( USPTO) web-site, the patent subclasses were treated as nodes and the co-occurrence relations were considered as edges in the constructed technology co-occurrence network. By applying the complex network method of "k-core", the co-occurrence network was analyzed and techniques were refined. The hierarchical evaluating indexes proposed were then applied to evaluating the techniques refined, and core techniques were recognized at last. The method proposed in this paper was verified by an example of laser cutting techniques.关键词
