"Preprocessing in Text Mining over data from the Microsoft SQL Server"
I 'm trying to read the text data from the Microsoft SQL Server ,which I am able to do using ' Database Example Source Operator' .
Now I have to do some pr-processing operation on the data which is in attribute "Title" .I have tried String Tokenizer
I'm getting following error
"Error in: StringTokenizer (StringTokenizer) The operator needs some input of type com.rapidminer.operator.TokenSequence which is not provided. Each operator defines which input is desired for applying this operator (these input objects are shown in operator info screen (F1)). Previous operators must load or produce the desired input objects. You can check the correct experiment setup by validating the experiment (via the icon or the menu item)."
Can to tell what I'm doing wrong
