I'm trying to test, how well a simple machine does at predicting a property of a text (specifically sarcasm).
I have my data in a massive table, where one colomn is the source, one is the label, that should be predicted and the last colomn is the text, the algorithm(s) should analyze.
The problem is without some tool to extract meaning or sentiment the results are (not surprisingly) abysmal.
Both the promotional texts on the Rapid-miner main page and the professor, who suggested I use Rapid Miner, imply that there are such tools already part of Rapid Miner, however I have not yet found anything in the documentation /manual.
What are these tools called/how are they used?
