摘要
本文对专利情报研究中的共现分析方法作了分类,将其分为共引、共词与共类分析3种。并结合专利地图分析探讨了3种分析方法的主要功能、作用及结果表现形式,通过制作专利地图,对3种共现分析所产生的结果作了解释,并对这3种共现分析方法的优缺点作了评述。
This article discussed the co - occurrence analysis methods, such as co- words, co - classifieations, co - citations, and presented their applications for patent mapping respectively.
