IBM has added a new feature to their Watson platform, a 'Tone Analyzer'. Basically what the feature will do is function like spell check and check the 'tone' of your email and make suggestions to help soften the tone if it thinks you are being too sarcastic. Fast Company has the full story.
"Much like a spell check," , "Tone Analyzer can be used to perform a 'tone check' to provide insights about three types of tones in a piece of text including emotion (negative emotions, cheerfulness, anger), social propensities (openness, agreeableness, and conscientiousness), and writing styles (analytical, confident, and tentative). It can even make suggestions for alternative word choices to soften or strengthen a desired tone."
