This manual, intellectually demanding task needs to be supported or even fully automated by classification systems that will classify patent applications, hopefully with an accuracy close to patent professionals. Like in many other text analysis problems, in the last years, this task has been studied using deep learning techniques. However, these techniques did not manage to reach a </span>classification accuracy<span> high enough to totally depend on. An ensemble system that combines multiple classifiers<span> obtaining better results could address this patent classification problem. However, this technique has not been explored in the domain of patent classification, and even in general, there are few studies focusing on the design of such systems. Our study investigates the design aspects of ensemble systems for patent classification and introduces an ensemble framework, which although is targeting the patent classification problem can be transferred to any other research domain.</span></span></p></div>","PeriodicalId":51794,"journal":{"name":"World Patent Information","volume":"75 ","pages":"Article 102233"},"PeriodicalIF":2.7,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49734089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, patent statistics are used to examine the changes in the technological capacity of the telecommunication sector<span> in China and shed light on the development of 5G<span> technology. Given full access to patent data, we find an increase in patent applications eventually leads to an increase in the innovation quality of the Chinese telecommunication sector. Firms, particularly industry leaders, greatly contribute to technological capacity by constantly producing high-quality innovation. Unlike those of previous studies, our findings reveal that a robust advancement reduces the technological capacity gap between the telecommunication sectors of the U.S. and China. Patent measures not only enable us to determine that Chinese telecommunication technology is at the gradual catch-up stage of the catch-up cycle, but also reveal responses to the technology window, the demand window, and the institutional windows of opportunity. Moreover, patent statistics can track knowledge flows. It can also find that accessing foreign knowledge has helped the Chinese telecommunication sector for learning and assimilating such knowledge to cultivate its knowledge base. We further find other than training qualified professionals, universities offer limited contributions to the technological capacity of the telecommunication sector.</span></span></p></div>","PeriodicalId":51794,"journal":{"name":"World Patent Information","volume":"74 ","pages":"Article 102219"},"PeriodicalIF":2.7,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49374586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
