Powerset——会回答问题的搜索引擎

最近发现一个很好玩的搜索引擎，不同于google和百度的是：再搜索的时候，我们可以是问一个问题，而不是一般的输入关键字，比如说，想知道美国哪个洲的收入税最高，我们就可以输入这么一个问题 "Which state has the highest income tax?" 在Powerset，相反的在google和百度上一般输入 "state income tax" 这个关键字，对于我们用户的好处是，这样在在Powerset上搜索出来的结果会接近我们想要知道的信息。Powerset的另外一个好处就是不用离开当前页面就可以看到详细的搜索结果，可以看看下面的例子，以"Powerset and google"为例，我想知道的是他们两者有什么区别，以下是Powerset呈现的结果：

试试其他的看看有没有新发现，用这个问题来问问"what do God hate"：出来的答案很好玩，有God hates homosexuals的、有God hates the US的、还有God hates the deceivers的，看来God是个好人。
要是用google搜"what do God hate"没有这么好玩了.




目前缺点是Powerset的结果现在还是来源于Wikipedia，貌似不支持中文搜索的。

Powerset’s goal is to change the way people interact with technology by enabling computers to understand our language. While this is a difficult challenge, we believe that now is the right time to begin the journey. Powerset is first applying its natural language processing to search, aiming to improve the way we find information by unlocking the meaning encoded in ordinary human language.

Powerset’s first product is a search and discovery experience for Wikipedia, launched in May 2008. Powerset’s technology improves the entire search process. In the search box, you can express yourself in keywords, phrases, or simple questions. On the search results page, Powerset gives more accurate results, often answering questions directly, and aggregates information from across multiple articles. Finally, Powerset’s technology follows you into enhanced Wikipedia articles, giving you a better way to quickly digest and navigate content.

A San Francisco-based company, Powerset was founded in 2005 and is funded by Foundation Capital, Founders Fund, Paperboy Ventures, and a number of angel investors.
