数据挖掘移动成为主流

RODNEY MONROE, the police chief in Richmond, Va., describes himself as a lifelong cop whose expertise is in fighting street crime, not in software. His own Web browsing, he says, mostly involves checking golf scores.

罗德尼梦露，在里士满，弗吉尼亚州警察局长，自己描述为终身制的警察，专门打击街头犯罪，而不是软件上。他自己的Web浏览，他说，主要是查看高尔夫成绩。

But shortly after he became chief in 2005, a crime analyst who had retired from the force convinced him to try some clever software. The programs cull through information that the department already collects, like “911” and police reports, but add new streams of data — about neighborhood demographics and payday schedules, for example, or about weather, traffic patterns and sports events —to try to predict where crimes might occur.

不过，不久后他担任2005年，犯罪分析师谁从空军退役让他试一试一些聪明的软件。通过信息，该署已收集像“911”和警察的报告程序扑杀，但增加了新的数据，街区人口统计和发工资的日期，例如，或者关于天气- ，交通模式和体育赛事-来预测犯罪会在哪里发生。“It sounded nutty at first,” Mr. Monroe recalled, “but the more and more you get into it, the more sense it makes.”

“起初这坚果，”门罗先生回忆说，“但是，越来越多的你就可以感受到，更有道理。”

The technology, for example, pointed to a high rate of robberies on paydays in Hispanic neighborhoods, where fewer people use banks and where customers leaving check-cashing stores were easy targets for robbers. Elsewhere, there were clusters of

random-gunfire incidents at certain times of night. So extra police were deployed in those areas when crimes were predicted.

这项技术，例如，指出了高比率的劫案在西班牙人的街区，在那里很少人使用银行和发薪日，客户随身携带现金商店很容易成为抢劫的目标。其他地方一样，都是随意开枪的事件集群在夜间的某些时候。因此，额外的警力部署在那些罪行时预测的地区。

The crime rate in Richmond declined about 20 percent last year, and it is down again this year.

The Richmond experience is part of a wave of sophisticated computing and mathematical analytics that is moving into the mainstream. Fueling the trend are the digitization of information, ever faster and cheaper computing, and the explosion of online networks and data collection.

在Richmond市的犯罪率下降了百分之二十左右，去年，这是今年再次下降。

Richmond的经验是一个复杂的计算，并正在成为主流数学分析浪潮中的一部分。加油的趋势是信息数字化，更快，更廉价的计算和在线网络和数据收集的爆炸。

The results, says Jon M. Kleinberg, a computer scientist at Cornell University, are a “revolution in measurement” and the “introduction of computing and algorithmic processes into the social sciences in a big way.” The phen omenon is strikingly evident in economics, business and crime prevention.

结果，乔恩米克莱因伯格说，康奈尔大学的计算机科学家，是衡量一个“革命”，以及计算和算法处理“到大张旗鼓地引入到社会科学。”这种现象是非常显着的经济，商业和预防犯罪。
