Microsoft's artificial intelligence 'chatbot' messes up again on Twitter

Almost a week after being shut down for spewing racist and sexist comments on Twitter, Microsoft Corp's artificial intelligence'chatbot' called Tay briefly rejoined Twitter on Wednesday only to launch a spam attack on its followers. "Tay remains offline while we make adjustments," a Microsoft representative said in an email. It was taken offline following the incident, according to a Microsoft representative, in an effort to make "adjustments" to the artificial intelligence profile. According to its Twitter profile, Tay is "an artificial intelligent chatbot developed by Microsoft's Technology and Research and Bing teams to experiment with and conduct research on conversational understanding."
