Question

我试图使用pyrouge来计算自动摘要和黄金标准之间的相似性。当它处理两个摘要时，Rouge工作正常。但是当它写出结果时，它会抱怨＆＃34;元组索引超出范围＆＃34;有谁知道导致这个问题的原因，以及我如何解决这个问题？

黄金标准是BookRags.txt，GradeSaver.txt，GradeSummary.txt，Wikipedia.txt 需要比较的摘要是automated.txt
不应该* .txt或[a-z0-9A-Z] +工作吗？但前一个给了我＆＃34;没有什么可以重复错误＆＃34;，后者＆＃34;元组索引超出范围＆＃34;错误

r = Rouge155("D:\ComputerScience\Research\ROUGE-1.5.5\ROUGE-1.5.5")
r.system_dir = 'D:\ComputerScience\Research\summary\Grendel\\automated'
r.model_dir = 'D:\ComputerScience\Research\summary\Grendel\manual'
r.system_filename_pattern = '[a-z0-9A-Z]+.txt'
r.model_filename_pattern = '[a-z0-9A-Z]+.txt'
output = r.convert_and_evaluate()
print(output)

我手动设置两个目录。似乎Rouge包可以处理其中的txts。

Answer 1

我在 pyrouge 软件包中遇到了同样的问题。发生此问题的原因是，源代码试图以某种模式匹配我们提供的文件名，否则将返回空元组。如果您想了解更多有关此信息，可以查看 Rouge155.py 文件。更具体地说，例如，检查函数 __ get_model_filenames_for_id（）。

我按照official page中提到的确切文件名说明进行了解析，如下所示：

r.system_filename_pattern ='some_name。（\ d +）。txt'

r.model_filename_pattern ='some_name。[A-Z]。＃ID＃.txt'

所以，我的建议是：

分别为system_summaries（系统生成）和model_summaries（人工生成/黄金标准）创建两个目录
提供指向这些目录的确切文件路径
如果将一个system_summary（例如SystemSummary.1.txt）与一组model_summaries（例如ModelSummary.A.1.txt，ModelSummary.B.1.txt，ModelSummary.C.1.txt）进行比较，然后提供以下模式：

      r.system_filename_pattern = 'SystemSummary.(\d+).txt'

      r.model_filename_pattern = 'ModelSummary.[A-Z].#ID#.txt'

您可以根据要评估的摘要数来扩展此范围。

希望这会有所帮助！祝你好运！

Answer 2

问题是流氓图书馆从未考虑过没有找到正则表达式匹配的情况。流氓源代码[AttributeUsageAttribute(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter, AllowMultiple = false)] class CheckboxIsCheckedAttribute : RequiredAttribute { public override bool IsValid(Object value) { Boolean isRequiredValid = base.IsValid( value ); if( !isRequiredValid ) return false; return (value as Boolean) == true; } }中的行是有问题的。如果您在documentation中查看，则表示群组功能id = match.groups(0)[0]。因为找不到匹配项，所以返回一个空元组，并且代码试图从空元组中获取第一项，这会导致错误。

pyrouge元组超出索引
