Abstract
Most of the studies related to technology analysis have focused on one specific technological field such as autonomous driving or blockchain. Most technologies have large and small relationships with each other. Therefore, it is necessary not only to perform technology analysis focusing on one target technology, but also to analyze several integrated technologies at the same time. In this paper, we propose a methodology for integrating technologies and analyzing the integrated technologies. We integrate patent big data for technological integration and use text mining, boosting, and ensemble for integrated technology analysis. To evaluate the performance of proposed method, we search the patent documents related to disaster artificial intelligence (AI) and extended reality (XR). In our case study, we integrate the patent data from disaster AI and XR technologies and analyze the integrated patent data using regression trees, random forest, extreme gradient boosting, and ensemble models. Therefore, we illustrate how our proposed method can be applied to the real domain.
Highlights
For effective analysis of convergence technology that combines two or more technologies, we study a methodology of patent big data integration and integrated technology analysis
We need to integrate various technologies and analyze the integrated technology for understanding the technologies. To cope with this need, we proposed a methodology of technology integration and integrated technology analysis in this paper
The combined patent documents of target technologies were used for integrated technology analysis
Summary
Most of the existing studies for technology analysis were about one target technology. Park and Jun (2017) studied statistical technology analysis for three-dimensional (3D) printing as a target technology [4]. For a more advanced technology analysis and a systematic understanding of convergence technology, there is a need to analyze two or more technologies at the same time. By this necessity, we propose a methodology for integrating technologies and analyzing integrated technologies.
