面向技术发展脉络分析的专利引证类时序模型及图谱研究
Patent Citation Class Time Series Model and Map for Technology Development Analysis
摘要
Abstract
The analysis of the technology development context is helpful to accurately grasp the direction of technological innovation and effectively identify the priority development technology field.In this study,the patents with citation relationship are used as the data source,and the calculation formula of patent citation relevance is proposed in combination with citation frequency and citation level.According to the patent citation relevance,the patents that play a core role in the process of technology development are selected as the research data set.The research data set is divided into subject domain,and time series is introduced to construct a three-dimensional class time series model of technology theme,technology field,and time series.Based on this model,a multi-dimensional patent citation knowledge map is drawn for multi-level technology development context analysis.The field of volatile organic compounds treatment technology is selected for empirical analysis,and the patent citation knowledge map of a technology in this field is constructed.The development context is analyzed from multiple dimensions.It is found that the technology is developed by the integration of the separation technology field and the acyclic or carbocyclic compound technology field,which verifies the usefulness of this research method.关键词
