The recent victory of IBM's Watson computer against human competitors in an exhibition round of Jeopardy got computer scientist Stephen Wolfram thinking about how regular search engines might fare in such a match-up. So he took 200,000 known Jeapardy clues and ran them through six search engines (Google, Bing, Ask, Blekko, Wikipedia Search, and Yandex). He excluded known Jeopardy sites from the results, and didn't test his own Wolfram Alpha because it is not designed for those kinds of queries. What he found is that the search engines did fairly well, depending on how you measure success. Google did slightly better than the rest, but Bing and Ask were close behind. On average, Google got the correct answer somewhere on its first results page 69 percent of the time, versus 68 percent for Ask and 63 percent for Bing. Google got the right answer somewhere in the title or snippet of text of the very top result 66 percent of the time, versus 65 percent for Bing (and Ask dropped to 51 percent).
