摘要
发明人合作是专利合作的主要形式之一,构建合作网络,分析网络演化特征,有助于把握发明人的合作趋势和规律。从网络拓扑性质、节点度分布、发明人合作模式、发明人共现的维度,对专利合作网络进行演化分析,探究专利发明人的合作特点,并在国内知识图谱领域进行实证研究。结果表明,该领域专利发明人合作网络具有一些典型的社交网络特征:具有明显的聚类效应,发明人之间的局部合作较为密切,且更倾向于和创新程度大的发明人进行优先合作,合作模式逐渐呈现多样化。该研究有助于挖掘专利合作网络中发明人合作的可能性,对未来知识图谱在专利合作领域上的发展趋势进行分析,提出相关启示,旨在促进国内知识图谱领域专利高质量发展。
Inventor cooperation is one of the main forms of patent cooperation.Building a cooperation network and analyzing the characteristics of network evolution will help to grasp the trends and laws of inventors’ cooperation.Analyze the evolution of the patent cooperation network from the dimensions of network topology,node degree distribution,inventor cooperation mode,and inventor co-occurrence,explore the characteristics of patent inventor cooperation,and conduct empirical research in the field of knowledge graph in China.The research results show that the patent inventor cooperation network in this field has some typical social network characteristics:it has obvious clustering effect,the local cooperation between inventors is relatively close,and it is more inclined to cooperate with the more advanced inventors.The cooperation model has gradually become diversified.This research is helpful to explore the possibility of inventor cooperation in the patent cooperation network,and then analyze the future development trend of the knowledge graph in the field of patent cooperation,and put forward relevant enlightenments to promote the high-quality development of patents in the field of knowledge graph in China.
