I am currently working on a new operator for Operator Toolbox. As you propably know we got an operator called "Dictionary Based Sentiment Analysis", which can use a list of words and associated scores to build a sentiment model.
As of now, you needed to provide your own dictionary to do this. I just wrote an operator which is providing these models right out of the box. I am currently added SentiNet.
Are there other dictionaries you would like to have in there? If yes, please post
