We released a major upgrade to our WordStat Sentiment Analysis Dictionary 2.0 that improves its accuracy and coverage. As always, we recommend that you tailor the dictionary to the subject matter you are analyzing but the latest version gives you a better starting point. You can download the dictionary on our website: Sentiment Analysis Dictionary.
We recently completed an analysis of the WordStat dictionary and several commercial and publically available sentiment dictionaries. We are writing a series of blogs on our analysis. Stay tuned to this newsletter and to our Blog page for those posts. We think you will find them illuminating.
