I am new to RM and am playing around with the text processing plugin. I got a question when comparing the OperatorsTextProcessing.xml and the operators list in RM. Here is what I did: I checked out the source of RM and text processing plugin from SVN; Did ant for the plugin and the .jar was copied into the lib/plugins folder in RM source folder. Now I am trying to match the operators listed in the OperatorsTextProcessing.xml file with the operators in the operators in RM. I find all the operators that I checked in the right place except one which is "attribute_space_transformation". According to the xml file it should under "data transformation" group, but in RM it is under "modeling/classification and regression/data transformation" group. Is this operator misplaced?
