I want to classify the forum posts using my own guideline except for the method rapidminer offers.For examle, I want to classify based on the keywords. If one post include one keyword, then I classify it into a class.
If it's just a short list of keywords you are using to classify you can use the Filter Documents operator to do this. This example process demonstrates one keyword matching per class, but you can also use Regular Expressions in the operator to expand this out to simple (small) lists or patterns.
