摘要
研究开发有效的方法和工具,以便从巨量、纷繁复杂的专利数据库中,快速便捷并简单明了地表达专利知识的进展,是近些年来专利研究的热点。本文以针对Web of Science开发的一种多元、分时、动态的新一代信息可视化技术——CitespaceⅡ为研究对象,解决了CitespaceⅡ不能用于专利知识可视化分析的瓶颈问题,并以德温特专利数据库中的数字通信技术为例,分别进行了发明者合作网络分析、专利权人合作网络分析和手工代码共现分析,实现了专利知识可视化的应用。本项研究扩展了CiteSpaceⅡ的应用范围功能,为专利数据的知识可视化研究提供了一种新方法。
In order to simply and conveniently express the progress of patent knowledge from the massive,complex patent database,we research on effective methods and tools to actualize it,which is a hot point in recent years.This paper studied CiteSpaceⅡ,which is a multiple,time-sharing,dynamic,new generation of visualization technology of information,developed for Web of Science,to resolve the bottleneck problem that CiteSpaceⅡcan＇ t be used to visualize Patent Knowledge,Derwent Innovations Index database in 1998-2008＂digital communication technique＂Citation data as an example,after data preprocessing, we actualizes the inventor cooperative network analysis、cooperation of institutions network analysis and manual codes cooccurrence analysis.This study extends the scope of application of CiteSpaceⅡ,which provides a new approach for the visualization of patent knowledge.
