根据分类器结果使用 rapidminer 将文件分类到文件夹中

Question

我需要帮助对 rapidminer 分类到标签（文件夹）中的文件进行排序，这个任务在 rapidminer 或读取结果示例集的 java 代码中是否可行？这是结果 table

即：我只想将文件拆分到代表其标签的文件夹中

这是示例集

    Data: SimpleExampleSet: 15 examples, 31988 regular attributes, 
special attributes = { label = #0: label (polynominal/single_value)/values=[test1] 
metadata_file = #1: metadata_file (polynominal/single_value)/values=[0.txt, 1.txt, 10.txt, 11.txt, 12.txt, 13.txt, 14.txt, 2.txt, 3.txt, 4.txt, 5.txt, 6.txt, 7.txt, 8.txt, 9.txt] 
metadata_path = #2: metadata_path (polynominal/single_value)/values=[D:\Finaltests\test1[=10=].txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt, D:\Finaltests\test1.txt] 
metadata_date = #3: metadata_date (date_time/single_value) 
confidence_sport = #31993: confidence(sport) (real/single_value) 
confidence_places = #31994: confidence(places) (real/single_value) 
prediction = #31992: prediction(label) (binominal/single_value) }

谢谢。

这个过程比我最初所说的稍微复杂一些，所以我在下面提供了一个示例。它假定 Linux 并将任何文件从 /tmp/old 复制到 /tmp/new/A 或 /tmp/new/B。 A和B由标签决定。

我使用 Copy File 来避免移动文件并造成损坏，希望您能看到它是如何工作的。

综上所述，如果你用旧名称和新名称制作属性，你必须使用 Loop Examples 来遍历每个示例。在这个循环运算符中，您必须提取要作为宏传递给 Copy File 运算符的值。

希望对您有所帮助。
