I am trying to build a sentiment analysis proof of concept, and am hitting the wall of getting my data. I found the "German Polarity Clues" dataset, but i can't quite make sense of the data format, can someone help me?
I need to make sense of the "probability" data field. Apparently there are three probabilities included there, but
1) It is not clear what probability we are talking of, is it p(word is contained| positive/negative/neutral sentiment), or is it p(positive/negative/neutral sentiment | word is contained)?
2) There are some negative values as well, what does that mean?
3) In most places there is a "-", but in some there is a 0, what is the distinction?
The dataset can be found here: http://www.ulliwaltinger.de/sentiment/

Thank you for your help!
