Sentilyze classifies tweets with positive or negative sentiment. Documentation is included in the .zip file. All files are included except data from twitter because that is not allowed under Twitter's TOS. You will have to acquire that data yourself. If you have questions about this please comment and I am willing to help out as much as I can. You can also get the ECL by cloning the Machine Learning Library repo at https://github.com/hpcc-systems/ecl-ml/.
