But why? IBM says in the same way that you spell-check a document, you can now "tone-check" it too. For instance, if you want an employee letter to be more "agreeable," Watson suggests changing the word "disappointing" to "unsatisfactory," and "difficult" to "challenging." By swapping out enough words, you eventually get the right level of "agreeableness" or "cheerfulness" in a passage. IBM thinks this could help, say, advertisers, to make sure a marketing campaign matches "the personality attributes of target customers." In other words, Watson can help companies hawk beer. Playing around a bit, I found it occasionally helpful, but it fell down more often than not. The main problem is that Watson was missing context, especially for words that have multiple meanings. In the sentence "I know the times are difficult!" it nonsensically suggested "arithmetic operation" for "times." It also doesn't understand sarcasm, humor and other styles, and just picks out individual words to determine the tone. That said, the Watson Tone Analyzer is impressive considering that it's still experimental. For fun, I had it analyze a financial story generated by another robot, Automated Insights' WordSmith. If you'll recall, it wrote that story in a competition against an NPR staff writer, with readers judging the final result. Watson found Wordsmith's article unremittingly cheerful (96 percent), conscientious (94 percent) and analytical (49 percent). In other words, you'll get the facts, but you won't have any fun reading them. In comparison, Watson found the same story from an NPR writer to be negative (90 percent), but it was overwhelming voted more enjoyable to read -- by humans, anyway.
IBM has launched its latest product in its " cognitive mapping " suite called the Watson Tone Analyzer . Once you input text , the system performs a " tone check " to highlight three different aspect of it - emotional , social and writing style . From this it can breakdown your overall tone and suggest new ways to " fix " it . In the same way you tone - check you can now " tone - check " it as well .
