摘　　要：从武汉大学图书馆OPAC系统获取为期18天的访问日志数据并对其进行清洗和处理,基于点击流数据分析框架的路径层开展数据分析。经划分、编码、筛选得到51410条待分析路径并按长度分为3组,利用Levenshtein Distance算法提取各组中心路径,以2D折线图的形式对其进行可视化。可视化分析揭示,用户访问OPAC系统留下的主要是包含3-10个页面的短路径,他们习惯于从图书馆主页进入OPAC,很少使用复杂的搜索方式,倾向于将OPAC作为查阅资源所在馆藏位置的工具。图书馆应考虑从界面和功能两个方面改善OPAC设计,以帮助用户更高效地利用馆藏资源。An 18-days transaction log file was firstly obtained from the OPAC of wunan University Li- brary, and then cleaned, prepared, and analyzed at the pathway level based on the clickstream data analysis framework. After data parsing, coding, and filtering, there remained 51,410 pathways which were divided into three clusters. The most typical pathway in each cluster identified with the Levenshtein Distance algo- rithm, was visualized in the form of 2D polyline graph. According to the Visualizations, users＇ visit to the OPAC mainly created short pathways consisting of 3 to 10 pages. The library should consider improve the design of the OPAC in terms of both interface and functionality, in order to help users make better use of library collections.
