专利群

之后，构建了专利知识元、专利知识链、专利知识群和专利知识网络四层次专利知识计量指标体系。

Therefore , a construction of indicator system has been established with a four level structure of patent knowledge unit , knowledge link , knowledge group and knowledge network .

专利丛林、专利组合和专利联盟&从专利战略到专利群战略

Patent Thicket , Patent Portfolios and Patent Alliance & From Patent Strategy to Patent Cluster Strategy

之后，本文采用关联规则挖掘算法Apriori中的频繁项集抽取了专利知识链，并借鉴复杂网络分析中凝聚子群的识别法，以Lambda集合算法完成了专利知识群的识别与计算。

In this research , patent knowledge link has been extracted with frequency item set of Apriori mining algorithms in association rules . Taking example by identification methods of complex network analysis , patent knowledge group has been recognized and calculated with Lambda Set from social network analysis .
