摘　　要：现有评估方法很少考虑模块间依赖关系程度,导致软件结构评估结果不能准确反映软件质量。基于PageRank思想计算软件中各模块的依赖关系权重,改进解耦水平(DL)的结构评价,开发了一个软件结构质量评价平台,并分别在6个数据集上实验,比较改进前后DL的准确度。实验结果表明,改进的DL在4个指标上都有较大提高,更能准确反映软件质量状况。In order to improve the situation that the lack of attention on the module dependency in the software leads to the inaccurate evaluation result of the software quality,we calculate the dependency weight of each module in the software on the basis of the PageRank idea to improve the decoupling level(DL)structural evaluation.We establish a software structure quality evaluation platform and experimentally compare the accuracy of DL before and after the improvement on six data sets.The experimental results show that the improved DL has a greater improvement in the four indicators,so it can reflect the quality of the software more accurately.
