So I've been trying to run a sentiment analysis on several csv filed containing tweets (using the Aylien extension), and the columns where the results should be keep turning up blank. I've tried all different kinds of operators (data to documents, select attributes, etc.) in all sorts of combinations, and nothing seems to fix it. What am I doing wrong? Please help. Thanks!

    very hard to say without seeing the process itself. Can you post it and maybe a short example data set?
