Ideal model for grouping comments

platanas20

Hi all,

I want to create a project that gets comments from an excel file.In the next step i want to automatically "group" the comments i took before in 3 categories(positive,negative,neutral).Is there any ideal model to do that? Please Help me.

Thank you very much!!!!!

Here is the XML code which takes the comments from an excel file and we use X-validation.Are we in the correct way?
Also there is a problem in Naive Bayes operator so we cant execute our project.Any help?Sry for my english!! ;D
