특허 빅데이터 분석을 통한 스포츠-가상현실 기술 모니터링 : LDA 알고리즘 기반 토픽 모델링의 활용

초록

Purpose The convergence of sports and virtual reality can be a new turning point for sports participation and business in a new way. Therefore, the purpose of this study is to derive the trend of technology and current promising fields by proceeding with sports-virtual reality patent topic modeling and trend analysis. Methods For domestic sports-virtual reality patent collection, 572 virtual reality-sports patent documents were collected from KIPRIS(www.kipris.com), a domestic patent portal operated by the Korean Intellectual Property Office, for 10 years (2012-2021). The collected original text data undergoes preprocessing and then LDA-based topic modeling, social network analysis for visualization, and trends using time series rarefaction coefficients. analysis was performed. Result As a result of the analysis, a total of 15 topics were derived, and they were classified from golf, baseball, winter sports, and riding sports in virtual environments to HMD, virtual reality relay, virtual training and rehabilitation, and biometrics and signal transmission of virtual systems. Through these results, the possibility of continuous development of screen golf-related patent technologies that have been in good standing throughout the period and the bright prospects of winter sports, broardcasting, signal transmission, and virtual training were confirmed. Conclusion Most of the patent clusters are young areas that are less than 10 years old to go downhill. Technological activation in the microscopic aspect and the situation where its prospects are not clearly revealed are not results in themselves, but the value of a turning point and the basis for establishing a technological strategy that maximizes the bright prospects of the future and making a new leap forward as a blank technology.
