基于引文网络的医学各学科间知识流动的规律与启示

摘要

The characteristics of knowledge exchange in medical field of China were analyzed by social network analysis with the medical data covered in CNKI Citation Database as its study object, which showed that both the inflow and outflow volumes of clinical medicine are the largest and form the core in knowledge exchange network, preclinical medicine is the theoretical base of other medical subjects and the important knowledge source in medical networks, the interchange is close between traditional Chinese medicine, surgery and other clinical subjects, oncology is rather active in interdisciplinary studies, the interchange between stomatology and psychology is rather rare with other clinical subjects in knowledge networks and stomatology and psychology are two independent subjects.Carrying out information push service for these subjects by making use of their characteristics can improve the targeted information service, step up the knowledge exchange between different medical subjects, and promote the cooperative interdis-ciplinary studies.%以CNKI引文数据库医药卫生专题下的数据为研究对象，利用社会网络分析方法，分析了我国医学领域内的知识交流特点。结果表明：临床医学的知识流入量和知识流出量都位居第一，是知识交流网络中的核心；基础医学是其他医学学科的理论基础，属于医学网络中的重要知识源；中医学与外科学及其他临床类学科的交流密切；在跨学科医学研究中肿瘤学表现得比较活跃；口腔医学和精神病学在知识交流网络中与其他学科的交流较少，是独立性较强的两个学科。利用这些特点开展学科信息推送服务，可提高信息服务的针对性，加速不同医学学科间的知识交流，推动医学领域内的跨学科合作研究。
