The Research on Domain-Specific Knowledge Graph Based on the RoBERTa-wwm-ext Pretraining Model written by Zhao Wei, a 2020 postgraduate freshman from the Institute of Cognitive Intelligence, together with his tutor, Liu Xingli, was contributed to the journal of Computational Intelligence and Neuroscience and published in October 2022. The journal JCQ is a sub category of General Computer Science Q2. Taking the open source data of military equipment as an example, this article explored the key technology of automatic construction of Domain-specific Knowledge Graph of the new generation of artificial intelligence. The results of this experiment have been verified by applying to the planned outsourcing topics of the national key research and development program undertaken by the Institute and the technical innovation part of the key project of the national social science fund presided over by Professor Ma Haiqun. On the one hand, the publication of these results has laid an effective training model support for the core chapters of master's thesis written by Zhao Wei, and on the other hand, it represents the continuous and steady improvement of the software engineering master's training level in our institute, which is worth learning. Congratulations! We look forward to the continuous efforts and news of success of the postgraduates in our college.
