如何使用Orange3從CSV文件中的列中提取頻繁項目集？

Question

Oragne3中頻繁的項目集小部件需要來自File小部件的輸入。包含「交易」的文件被認爲是一個籃像例如：

Bread, Milk 
Bread, Diapers, Beer, Eggs 
Milk, Diapers, Beer, Cola 
Bread, Milk, Diapers, Beer 
Bread, Milk, Diapers, Cola 

但我的文件實際上有一個用戶ID的列，並與實際交易中的第二列，這樣的事情：

XYZ001, "Bread, Milk" 
XYZ002, "Bread, Diapers, Beer, Eggs" 
XYZ003, "Milk, Diapers, Beer, Cola" 
XYZ004, "Bread, Milk, Diapers, Beer" 
XYZ005, "Bread, Milk, Diapers, Cola" 

如何將事務（第二列）傳遞給頻繁的項目集小部件？

Answer 1

變換你的籃子文件是這樣的：

user=1, Bread, Milk 
user=2, Bread, Diapers, Beer, Eggs 
user=3, Milk, Diapers, Beer, Cola 
user=4, Bread, Milk, Diapers, Beer 
user=5, Bread, Milk, Diapers, Cola 

然後做任何你想做的（即帶）的user列？
