【摘要】：提出了一个建立在专利全引用信息基础上的技术知识扩散特征研究框架,运用专利引用和文本挖掘的方法,通过研究施引专利和被引专利,从技术知识的利用和技术知识的传播两个角度,更全面地探索技术知识扩散的特征。首先提取基本专利和引文专利之间的引用关系,获得技术知识扩散的范围;其次利用文本挖掘的方法抽取专利摘要中的技术关键词,并计算基本专利与引文专利间的文本相似度,衡量出技术知识扩散的程度;然后运用文本聚类和语义分析法进行专利的技术知识扩散特征分析,提炼出6种技术知识扩散特征下分别对应的技术主题。从专利文本的内容着手,将其与引用相结合进行技术知识扩散特征的研究,并对尚未出现前向引用关系的专利进行了技术知识扩散潜力的测度,减少了以往研究的局限性。最后用石墨烯技术作为实证进行了研究,验证了该方法的可行性和有效性,也为石墨烯技术的发展提供了决策支持。
[Abstract]:In this paper, a research framework of technical knowledge diffusion characteristics based on patent full citation information is put forward. By means of patent citation and text mining, patent citation and cited patent are studied. In this paper, the characteristics of technological knowledge diffusion are explored from two aspects: the utilization of technical knowledge and the dissemination of technical knowledge. Firstly, the citation relation between the basic patent and the citation patent is extracted, and the scope of technical knowledge diffusion is obtained. Secondly, the technical keywords in the patent abstract are extracted by the method of text mining. The text similarity between basic patent and citation patent is calculated to measure the degree of technical knowledge diffusion, and then the characteristics of technical knowledge diffusion of patent are analyzed by text clustering and semantic analysis. Six technical topics corresponding to the diffusion characteristics of technical knowledge were extracted. Starting from the content of patent text, this paper studies the characteristics of technical knowledge diffusion by combining it with citation, and measures the potential of technical knowledge diffusion for patents that have not appeared forward citation relation, which reduces the limitation of previous research. Finally, the graphene technology is used as an empirical study to verify the feasibility and effectiveness of the method, and to provide decision support for the development of graphene technology.
