To classify customer queries using RapidMiner
I have a huge excel file, which has general attributes like BILLID, CLAIM ID, ITERATION ID, QUERY TEXT etc. I want to classify these queries to identify major bulk of problem areas. I tried employing Decision Tree, but it did not render any insights. Most of what I researched I stumbled upon using filter keywords, Tokenizing, Stemming to identify keyword frequency, But I couldn't use it for excel attribute, irrespective of that I am not sure that would help me in finding clusters/buckets of complete query statement rather than just keywords. Any help in finding right direction would be of much help, Thank You.
