Abstract  

[Objective] This paper reveals the evolution of patents from knife-scissor industry in Guangdong Province, China.[Methods] Firstly, we proposed a new classification scheme. Secondly, we created a topic model with TRIZ feature based on LDA. Thirdly, we calculated the first n words with high probability in different years and fields. Finally, we predicted the patent evolution path in the next three years.[Results] The new classification method reduced the noise of manual annotation to less than 10%. We also found that patents from knife-scissors enterprises in Guangdong mainly focused on the TRIZ rules, such as shapes, structures, movement modes, and materials.[Limitations] We only studied the knife-scissors industries.[Conclusions] The proposed method identifies key technical developing trends of knife-scissors industries in Guangdong and gives suggestions on their upgrading in the future.
