摘　　要：开展基于社会化标签系统、搜索引擎和分类目录3种平台的信息搜寻实验,从相对查全率、相对查准率两个指标的角度比较分析社会化标签系统与其他网络信息搜寻系统的搜寻效率。研究发现,搜索引擎的相对查全率和相对查准率最高,社会化标签系统的搜寻效率也有一定的优势。分类目录比社会化标签的相对查准率低,两者的相对查全率接近。对于某些特定的信息需求,社会化标签系统的搜寻效率甚至超过了搜索引擎。The paper takes a comparative experiment on basis of the social bookmarking systems, search engines and directories, and discusses the search efficiency of the social bookmarking systems with other network information searching systems from the perspective of the relative recall and relative precision. The results show that the search engines in the study had the highest relative precision and relative recall, and the social bookmarking systems fared surprisingly well. Overall the directories were less precise than the social bookmarking system, but they had similar recall scores. It is also found that on some specific information needs, the search efficiency of the social bookmarking system is better than search engine.
