关键技术挖掘与企业技术竞争情报——以DVD激光头技术为例

Key Technologies Mining and CTI in Enterprises——Taking the Case of DVD Optical Pickup Technology as an Example

以美国专利商标局(USPTO)1995-2004年的专利数据为基础,利用关键词检索与专利引文检索相结合的方法来构建DVD激光头相关主题的专利数据集,用专利文献耦合和专利引证关系的文献计量学方法挖掘DVD激光头技术中的关键技术,获取企业技术竞争情报。

Based on the data of USPTO from 1995 to 2004, the authors construct a patent data set of DVD optical pickup by retrieving the patents through keywords access and searching the patent citations. The authors also analyze the evolution of technological sub-topics of DVD optical pickup by patents citation analysis, especially by citing patents coupling,and then get CT(Icompetitive technical intelligence) in enterprises.
