Abstract

[Purpose/Significance] The identification of technological opportunities is an important prerequisite for the smooth development of technological innovation activities of enterprises. It is of great significance to discover and grasp valuable technological opportunities in time for technological innovation breakthrough. [Method/ Process] In this paper, a technology opportunity identification method was proposed from the perspective of topic mining and patent evaluation. Firstly, the technology topics covered by the technology field were identified by the topic model and the patent clustering was carried out. Then, the fine-grained analysis was carried out at the level of technology topics. This paper comprehensively considers the three important characteristics of technological opportunities: frontier, value and timeliness. The mutation progression method and outlier factor algorithm were used to evaluate the high-value patents and outlier patents in the technology topics to form the core patent set, and the average age of patents for each technology topic was calculated. Finally, the proportion of core patents in the technology topic and the average age of patents were taken as the core indicators to draw the technology opportunity identification map to identify the opportunities in the technology field. [Result/Conclusion] Taking the field of smart agriculture as an example, the proposed method is empirically demonstrated, and five technological opportunities in the field of smart agriculture are identified, which provides decision support for the technology R&D of innovation subjects. However, the quantitative verification of identification results and the fusion of multi-source data for technical opportunity identification need to be further explored.

Key words： topic model; value evaluation; technology opportunity; smart agriculture
