[目的/意义]识别新颖专利代替由一组关键词代表的专利空白,改善技术机会识别过于主观的缺陷。[方法/过程]利用一种基于系统流程的定量方法识别专利的新颖程度。通过基于密度的局部离群点(DLOF)算法识别出新颖专利,利用技术范围指标与同类专利数量指标构建研发组合标识图。[结果/结论 ]研究结果表明,基于专利的新颖性研发组合标识图可以准确地识别出新颖专利,为技术研发提供借鉴。
[Purpose / Significance] Identify novel patents Instead of patenting gaps represented by a set of keywords, improve technical opportunities to identify subjective deficiencies. [Method / Procedure] Identify the novelty of a patent using a quantitative approach based on systematic processes. Identify novel patents through density-based local outlier (DLOF) algorithms, and construct R & D portfolio logo using technical indicators and similar patents. [Results / Conclusions] The research results show that the patent-based novelty developed combinatorial map can accurately identify new patents and provide reference for technology research and development.
