摘要
在对专利引文可视化技术现状进行分析的基础上,将基于引文分析的时间线技术运用到专利文献的可视化分析。详细阐述该技术的理论依据、设计思想,并用美国专利数据库中的DVD激光头专利进行技术应用,证明该技术能揭示专利文献中的技术热点及其发展演变,并挖掘关键技术。
Following a review of visualization techniques of patents citation analysis, this paper introduces timeline technique to patent citation analysis for the first time. The authors expound the theoretical basis and design ideas of timeline. DVD pickup patents from USPTO are applied to prove that the technique can reveal the technology fronts and its evolution among patent documents, and mine the key technologies.
