According to Eric Brown, an IBM research assistant, he and his 35-person team wanted to get Watson to sound more like a real human. After teaching IBM's super-computer the entire Urban Dictionary, however, Watson simply couldn't distinguish polite discourse from profanity. Watson unfortunately learned all of the Urban Dictionary's bad habits, including throwing in overly-crass language at random points in its responses; in answering one question, Watson even reportedly used the word "bullshit" within an answer to one researcher's question. In the end, Brown and his team were forced to remove the Urban Dictionary from Watson's vocabulary, and additionally developed a smart filter to keep Watson from swearing in the future."
