技术领域中的专利知识群分析——以SIPOD中的H04L领域为例

Analysis of Patent Knowledge Group in Technological Field

文章从技术知识分解和技术知识的再认识出发,描述了专利知识群的形成,并构建了专利知识群强度和专利知识群聚集度指标,以我国国家知识产权局数据库中H04L领域"数字信息的传输"为例,开展了实证研究。研究发现H04L领域"数字信息的传输"中强度为66的知识群聚集度最高为0.993,主要是数据通信网络系统方面的研究,起着区别于其他技术领域的作用。

At first, this paper introduces the knowledge decomposition and its reconstruction, and describes how the knowl- edge group takes shape. Then, the paper constructs two indicators including patent knowledge strength and patent knowledge cluster to analyze the patent knowledge group in the field of H04L in the State Intellectual Property Office Database. Finally, the result shows that the core knowledge group is the research data communication network system with knowledge strength 66 and knowledge cluster 0. 993, which plays the role different from other technological fields.
