专利信息内容挖掘及其试验研究

Experimental Study of Patent Information Content Mining

随着专利数据量的激增和新技术领域的交错重叠,迫切需要在专利信息分析中深化到内容层次,内容挖掘是其中的重要途径和必要手段。借鉴文本内容挖掘的思想和技术,提出基于内容挖掘的专利信息分析的方法体系,分别阐述方法体系中包含的专利文本信息预处理、专利信息内容分析和专利信息知识处理过程的主要步骤及其涉及到的各种技术和算法。最后,以混合动力汽车领域专利信息的内容挖掘为例进行实证研究。

With the explosion of patent amount and stagger overlapping of new technique field, there is urgent need to deepen to content level in patent information analysis. Content mining is important approach and necessary means. Using the thought and technology of text - content mining, the content mining - based patent information analysis method system, and expounds the major steps and the various techniques and algorithms of the patent text information pretreatment, patent information content analysis and patent information knowledge treatment. Finally, the paper selects patent data in the area of Hybrid Electric Vehicle （HEV） to do empirical research.
