LDA 기반의 토픽모델링을 이용한 철도차량용 무선급전시스템 연구 동향 분석

초록

Research on WPT (Wireless Power Transfer) technologies for locomotives based on large-capacity wirelesspower transmission systems is underway, and interest pertaining to this technology is also increasing in relatedindustries. Although there is a growing trend for analysis in both domestic and overseas markets, research thatsupports strategies through detailed technology classification and analysis of the trends for WPT technology forlocomotives are insufficient. Therefore, this study is intended to produce detailed research topics, which analyzeWPT technology for locomotives, by topic modeling based on the LDA (Latent Dirichlet Allocation) algorithmand to extract topics by time series analysis. It is expected that the WPT technology for locomotives derivedfrom this study and its results will be used to effectively establish the research direction in the future.
