Engineering ethics education is an indispensable part of higher engineering education reform. The research on engineering ethics education gets more attention forms researchers under the background of “New engineering”. Based on the processing of Natural language processing(NPL), with the support of SLatent Dirichlet Allocation(LDA)technology and metrological visualization tool, this article selected 212 research literatures collected in CNKI. Based on literature research overview, keywords frequency list, and documents co-citation network, this paper analyzed the research status, essential document, and hot topics in this domain based on the environment of machine learning . Besides, the problems that impeded the development of engineering ethics education were proposed. Finally, this paper proposed some suggestion to solve these problems in term of country, society and universities. This study provides an effective reference for promoting engineering ethics education in higher engineering education.
