摘要
为全面、准确地揭示技术发展脉络和发展态势,提供技术主题演化的整体视角,提出一种基于时序主题关联与主题价值评估的技术主题演化分析方法。基于专利数据,依据技术生命周期S曲线动态划分时间窗口,利用LDA主题模型识别各时间窗口的技术主题,从时序主题关联和主题价值评估2个视角对技术主题演化路径进行全面探析。基于生物制药产业进行实证研究,揭示生物制药相关技术的演进路径和发展状态,验证所提方法的可行性和有效性,为相关企业的技术创新提供科学的理论支持。
To comprehensively and accurately reveal the context and trend of technological development,and provide the overall perspective of technological topic evolution,a technological topic evolution analysis method based on temporal topic correlation and topic value evaluation is proposed.Based on patent data,the study dynamically divides the time windows according to the S-curve of the technology life cycle,uses the LDA topic model to identify the technological topics in each time window,and makes a comprehensive analysis on the evolution path of the technological topics from the perspectives of temporal topic correlation and topic value evaluation.Bio-pharmaceutical industry is selected for the empirical study.The evolution path and development state of bio-pharmaceutical related technologies are revealed,the feasibility and effectiveness of the proposed method are verified,and scientific theoretical support is provided for the technological innovation of related enterprises.
