目的:通过分析影响信息检索质量的深层次原因,提升网络健康信息资源的描述质量。方法:选取中英文综合搜索引擎、医药健康信息网共12个网站作为检索工具,选取5个2013年度生物医学热词作为检索词,分别在每个网站输入每个检索词,查看前10条检索结果的HTML源代码中HEAD文件的"Title"、"Keywords"及"Description"3个数据标签,根据其中是否包含检索词赋以权重,对12个网站的调查结果进行分组比对统计分析。结果:综合性搜索引擎网站的得分优于医药健康信息网,中文网络信息资源的得分优于英文网络信息资源。结论:当前网络健康信息资源描述质量整体较差。只有加强健康信息网络建设、提升健康信息资源描述质量,才能为用户提供实时的更准确的健康信息。
