Abstract： [Purpose/significance] The discovery of core patents is an important part in technological innovation, which is of great significance to the technological improvement and the patent strategy layout.[Method/process] This paper firstly defined the concept of core patent. Then, by introducing the original PageRank algorithm model, the improved PageRank——PatentRank (referred to as PTR) was put forward, which combining the cited times of patents and the patent age. Finally, we applied the new model to the field of OLED to identify the core patents.[Result/conclusion] We find that compared with the cited times, PTR can not only identify the core patents but also some basic important patents which provide the research ideas for the research of OLED technology. Besides, compared with the original PageRank algorithm, the values of PTR have higher degree of differentiation, and it can improve the PR results on the local scale.

Abstract： [Purpose/significance] Through literature review on the concept of disruptive technology at home and abroad and existing methods of identifying disruptive technology, this paper analyzes the existing problems and proposes possible research perspectives on future disruptive technology identification.[Method/process] Six identification methods of subversive technology were summarized by means of literature research, and their advantages and disadvantages were analyzed.[Result/conclusion] Disruptive technology identification method also has some disadvantages, such as the characteristics of disruptive technology classification is not clear, lack of quantitative research, the existing recognition methods lack of considering the correlation between technical knowledge, the future research should further strengthen the characteristics of disruptive technology research, and to consider the link between the knowledge characteristics, and strengthen the identification of disruptive technologies from the perspective of numerical breakthroughs in efficacy features and technology convergence. In addition, researchers should dig deeper into finer-grained technical topics.
