摘　　要：软件度量是保证软件质量的重要方法,程序切片是一种针对切片标准简化程序的技术。提出了一种基于粗粒度程序切片技术度量面向对象程序模块耦合度和类内聚度的量化方法,扩展了粗粒度程序切片的含义,基于面向对象系统依赖图进行程序切片,给出了对应的算法实现,利用切片技术度量了模块耦合度和类内聚度。In order to improve the precision ratio of search engine ,the weighted global similarity ranking algorithm based on group user interesting model was presented. The ranking algorithm integrated global similarity between the query result and the user＇s search intention. The search engine ranking results were improved. The algorithm provided users with more accurate search services. The experimental results show that the precision ratio of search engine is markedly improved; the ranking algorithm can rank high relevancy results between the query result and the user＇s search intention in the front of the list.
