| 摘 要： | 【目的/意义】基于文献数据的领域知识图谱构建有助于探测某学科领域的主要研究内容及其发展方向,是进行技术创新的基础情报工作,对于研究人员、企业都具有一定的意义。【方法/过程】提出基于交互式可视化技术的知识图谱构建方法,首先基于经典LDA模型进行主题识别,然后基于社会网络分析方法构建领域主题网络识别关键主题词;最后,基于JS(D3工具)绘制可交互的关键主题词关联与检索知识图谱,发现关键主题词的隐含联系,辅助进行领域知识挖掘与分析。【结果/结论】通过对我国医疗健康信息领域进行实证研究,验证了本文提出方法的准确性和有效性。

| Abstract: | 【Purpose/significance】Domain knowledge map construction based on document data is helpful to explore the main research content and development direction of a certain discipline field. It is the basic information work for technological innovation, and has certain significance for researchers and enterprises.【Method/process】A method of knowledge map construction based on interactive visualization technology is proposed. Firstly, topic recognition is performed based on classical LDA model, and then domain topic network is constructed based on social network analysis method to identify important subject words. Then, interactive key subject word association and retrieval knowledge map are drawn based on JS(D3 tool), and hidden relation of core subject words is found to assist in leading domain knowledge mining and analysis.【Result/conclusion】Through the empirical research on the field of medical health information in China, it verifies the accuracy and effectiveness of the proposed method. |
