Firm beats giants with predictions
China's national soccer team failed to make the cut for the 2014 World Cup, but that hasn'tshaken a Chinese tech company's credibility in predicting game results.
Baidu's World Cup prediction service has outscored its major competitors by accuratelypredicting winners 58.3 percent of the time, compared with runnerup Microsoft Bing's 56.2percent.
The Beijing-based company not only correctly chose the four semifinalists, it also predicted thatGermany would win its match with Brazil, though it didn't foresee the 7-1 score.
Baidu said that its World Cup prediction model is based ondata from as many as 37,000 matches played by 987 teamsover the past five years.
To improve the accuracy of the model, Zhang Tong, head ofthe Beijing Big Data Lab of Baidu, said that the companyalso took into consideration five factors: the teams' strength,home advantage, recent game performance, overall WorldCup performance and bookmaker odds.
Tech companies such as Baidu, Microsoft, Google andYahoo, and investment banking firms such as GoldmanSachs and Deutsche Bank, all took their chances predicting2014 World Cup games.
Generally speaking, tech companies outperformed WallStreet investors. Baidu and Microsoft both correctly chosethe four teams in the semifinals. Goldman Sachs erred inpicking Spain to reach the final four, while Deutsche Bankeven predicted that England would win the tournament.
Bryan Wang, principal analyst with Forrester Research, a multinational technology and marketresearch firm, said that as a company that processes search requests every day, Baidu enjoysan edge in big data-based prediction.
He said accuracy is based on how much data companies use in building the models. "The moresoccer-related data you put into the model, the more accuracy you get," he said, adding thataccuracy isn't necessarily equal to a company's capability in big data technology.
Recent media reports said that a soccer-loving girl in Northeast China won more than 3.3 millionyuan ($528,000) from betting on the 2014 World Cup and her secret weapon was Baidu's WorldCup predictions.
But Bi Yajing, a soccer fan in Beijing who has spent 1,000 yuan on soccer lotteries during theWorld Cup, said he never uses such big-data prediction. "There is no fun if you can't vote for yourfavorite teams," he said.
