摘　　要：[目的/意义]针对当前我国健康类搜索引擎可用性程度较低、用户满意度不高的现状,对3个常用健康类搜索引擎的可用性进行评估,以期促进该类搜索引擎技术的发展,提高信息服务质量。[方法/过程]从用户视角出发,采用实验研究方法,探讨并比较"有问必答""好大夫在线"和"39健康搜"3个健康类搜索引擎的有效性、效率和满意度。[结果/结论]3个搜索引擎在系统反应速度和易学程度方面较好,但查准率还有待提高;返回网页虽内容丰富,但同时还存在重复、啰嗦、不严谨等问题。本研究发现,用户对健康信息的主观评价与基于临床证据的评价结果有所冲突,如何调和二者之间的矛盾,建立更为全面且有效的健康信息评价指标体系有待进一步研究。[ Purpose/significance ] The user is dissatisfied of China＇ s health search engine with low usability. This study explores the usability of three general health search engines, in order to promote the development of this kind of search engine and improve the quality of information service. [ Method/process] By an experiment, it discusses and compares the effectiveness, efficiency and user＇ s satisfaction of ＂120ask＂, ＂haodf＂ and ＂39so＂ from the user＇ s perspec- tive. [ Result/conclusion] Results indicate that three search engines all have good response speed and learnability, but their precision needs to be improved. The system returns rich information, but has some problems, such as information repetition, redundancy and imprecision. The subjective assessment of health information from user and evaluation result based on clinical evidence have conflict. It is necessary to study how to balance the conflict between them and develop a comprehensive and effective evaluation index system of health information.
