摘要
分析工程建设监管平台特征,指出平台结构优化的必要性。考虑到不同路径对用户的重要性不同且平台流程复杂,难以统一支持度阈值,采用多最小支持度加权频繁模式算法构建挖掘模型,并根据权值大小对不同路径设置不同的支持度阈值,以尽可能挖掘用户感兴趣的路径集。最后对广西水利建设项目监管平台用户日志进行实验,找出用户频繁访问路径,为平台用户使用体验的优化提供决策支持。
This paper analyzes the characteristics of engineering construction supervision platform,and figures out the necessity of platform structure optimization.Considering that different paths have different importance to users and that the platform process is complex,which make it difficult to unify the support threshold value,this paper usesmultiminimum support weighted frequent pattern algorithm to build the mining model.Different support thresholds are set for different paths according to the weight sizeso as to mine as much as possible path sets of user interest.Finally,the user log of Guangxi water conservancy construction project supervision platform is tested to find out the frequent access path of users and to provide decision support for the optimization of user experience of the platform.
