目的 利用数据挖掘技术对半结构化数据的土家族医药进行品种规范和常用功效的可视化发现。方法 收集整理《中国民族药辞典》、《土家医方剂学》等土家族代表性医药文献，建立土家族医药原始数据库，包含药物拉丁学名、药用部位、性味、毒性、功效、主治疾病等。借助Visual FoxPro 9.0软件对土家族医药特性进行频次统计和品种规范，主要以法定标准收录；借助TCMISS (V2.5)、Cytoscape3.6.1、Gephi0.9.2等软件对土家药“药物-功效-主治”间的语义关系，进行功效挖掘和可视化展示。结果 筛选土家药共1453味，方剂共771首，其中土家药主要以“寒（凉）、平”性偏多，苦味药频次最高，其次是辛味药、甘味药；清热败毒、赶风除湿等功效出现频次最高；皮肤疮癣、妇科疾病等是关联程度较大的主治病症。结论 土家族医药的品种规范和“药性-药味-功效-主治”隐形关系可视化分析，可为完善土家药信息化研究奠定基础。
Objective The data mining technology was used to visually discover the variety specification and common efficacy of Tujia medicine with semi-structured data. Methods The representative medical documents of Tujia such as Chinese National Medicine Dictionary and Tujia Medical Formulary was collected and sorted out to establish the original database of Tujia medicine, including Latin scientific name, medicinal position, sexual taste, toxicity, efficacy, and indication of diseases, etc. With the help of Visual FoxPro 9.0, researching the frequency statistics and variety specifications of Tujia medicine was made. With the help of TCMISS (V2.5), Cytoscape 3.6.1, Gephi0.9.2 and other software, researching the semantic relationship between Tujia medicine "medicine-efficacy-indication" was explored and visually displayed. Results A total of 1453 Tujia medicines with 771 prescriptions were screened, of which Tujia medicines were mainly cold (cool) and mild, bitter medicines had the highest frequency, followed by pungent medicines and sweet medicines. The efficacy of clearing away heat and toxic materials, expelling wind and dehumidifying had the highest frequency. Skin sores and tinea, gynecological diseases and so on were the main indications with a greater degree of correlation. Conclusion The visualization of the hidden relationship between Tujia medicine variety specification and "Property-Taste-Efficacy-Indication" can provide an effective reference. It laid a foundation for the improvement of Tujia medicine information research.
