摘　　要：目的当前公众对海洋中药信息了解不足,且缺乏海洋中药相关知识服务工具,为解决这一问题,研究开发海洋中药智能问答系统,为公众提供海洋中药知识查询工具。方法以前期构建的细粒度海洋中药知识图谱MMKG为知识库,综合利用Aho-Corasick、Word2Vec等算法获取海洋中药实体,从专业角度提出了一种细粒度海洋中药问题分类方法,构建海洋中药智能问答系统(MMKGQA)。结果通过问卷调查的问题语料测试,本系统在回答海洋中药常见6大类问题的平均精确率、平均召回率、平均F1值分别为97.93%、83.41%、89.10%,表明本系统能很好回答海洋中药的相关问题,具有较高的实用性和可行性。结论本系统可以帮助普通用户获取海洋中药的科普知识,为海洋中药研发人员的相关知识获取提供一种有效的知识服务工具,助力海洋新药研发。Objective In order to solve the problem of insufficient public understanding of the information of Marine Traditional Chinese Medicine and the lack of relevant knowledge service tools of Marine Traditional Chinese Medicine,the research and development of an intelligent question-answering system for Marine Traditional Chinese Medicine have been carried out,to provide a tool for public to inquire the knowledge of Marine Traditional Chinese Medicine.Methods The knowledge base is based on the fine-sized Marine Traditional Chinese Medicine knowledge graph MMKG constructed in the early stage.Aho-Corasick,Word2Vec and other algorithms were used to obtain Marine Traditional Chinese Medicine entities.From the professional point of view,a fine-sized classification method for Marine Traditional Chinese Medicine questions was proposed,and an intelligent Marine Traditional Chinese Medicine question answering system(MMKGQA)was constructed.Results The average accuracy rate,average recall rate and average F1 value of the system were 97.93%,83.41%and 89.10%,respectively,through the question corpus test of the questionnaire survey.It shows that the system can answer the relevant questions of Marine Traditional Chinese Medicine well and has high practicability and feasibility.Conclusion This system can help common users to obtain the popular science knowledge of Marine Traditional Chinese Medicine and provide an effective knowledge service tool for the researchers of Marine Traditional Chinese Medicine to acquire relevant knowledge and help the research and development of Marine new drugs.
