IBM Waton is trying to redeem Internet communication by putting an end to passive-aggressive emails. The tech company this week introduced an instant tone analyzer that uses linguistic analysis to assess the tone of emails or blogs or text message. “Tone Analyzer analyzes given text and provides insights about the emotional, social and writing tones reflected in that text,” explained one of the IBM scientists. For emotional tone, IBM Watson somehow perceives your intended emotion, like anger, negativity or happiness. The program even analyzes the openness and agreeability of your text. And Tone Analyzer doesn’t stop there: it helps you edit your email to be open and positive. Your online hospitality rating is about to increase.
