Google Execs, James Cameron Plan Space Venture

April 22, 2012 Leave a comment

Google CEO Larry Page and the company’s executive chairman Eric Schmidt have joined forces with Avatar director James Cameron for a space venture that will possibly involve mining asteroids.

The venture, Planetary Resources Inc., plans to “overlay two critical sectors — space exploration and natural resources — to add trillions of dollars to the global GDP” and “help ensure humanity’s prosperity,” according to a press release issued by the company this week. More details will be forthcoming when the company formally unveils its plans at an event in Seattle on Tuesday.

The three aren’t the only ones involved. Planetary Resources was co-founded by former NASA Mars Mission Manager Eric Anderson and Peter Diamandis, the commercial space entrepreneur. Charles Simonyi, a former top executive at Microsoft, and K. Ram Shriram, a Google director, are also backing the company. Ross Perot Jr., son of billionaire H. Ross Perot, is also a backer.

For Cameron, the venture may be a case of life imitating art: His 2010 blockbuster Avatar‘s plot involved mining resources on alien planets.

Inside view on ads review

April 21, 2012 Leave a comment

The Official Google Blog

via Inside view on ads review.

 

This is the first in a series of posts that will provide greater transparency about how we make our ads safer by detecting and removing scam ads. -Ed.

A few weeks ago, we posted here about our efforts in fighting bad ads, and we shared a video with the basics of how we do it. Today I wanted to delve a little deeper and give some insight into the systems we use to help prevent bad ads from showing. Our ads policies are designed with safety and trust in mind—we don’t allow ads for malicious downloadscounterfeit goods, or ads with unclear billing practices, to name a few examples. In order to help prevent these kinds of ads from showing, we use a combination of automated systems and human input to review the billions of ads submitted to Google each year. I’m one of many engineers whose job is to help make sure that Google doesn’t show bad ads to users.

We’ve designed our approach based on a three-pronged strategy, each focused on a different dimension of the problem: ads, sites, and advertiser accounts. These systems are complementary, sharing signals among each other so that we can comprehensively attack bad ads.

For example, in the case of a site that is selling counterfeit goods, this three-pronged approach aims to look for patterns that would flag such a site and help prevent ads from showing. Ad review notices patterns in the ads and keywords selected by the advertiser. Site review analyzes the entire site to determine if it is selling counterfeit goods. Account review aims to determine if a new advertiser is truly new, or is simply a repeat offender trying to abuse Google’s advertising system. Here’s more detail on how we review each of these three components.

Ad Review
An ad is the snippet of information presented to a user, along with a link to a specific webpage, or landing page. The ads review system inspects individual ads and landing pages, and is probably the system most familiar to advertisers. When an advertiser submits an ad, our system immediately performs a preliminary examination. If there’s nothing in the ad that flags a need for further review, we tell the advertiser the ad is “Eligible” and show the ad only on google.com to users who have SafeSearch turned off. If the ad is flagged for further review, in most cases we refer to the ad as “Under Review” and don’t show the ad at all. From there, the ad enters our automated pipeline, where we employ machine learning models, a rules engine and landing page analysis to perform a more extensive examination. If our automated system determines an outcome with a high degree of confidence, we will either approve the ad to run on Google and all of our partners (“Approved”), approve the ad to show for appropriate users in specific locations (“Approved – Limited”) or reject the ad (“Disapproved”). If our automated system isn’t able to determine the outcome, we send the ad to a real person to make a final decision.

Site Review
site has many different pages, each of which could be pointed to by different ads, often known as a domain. Our site review system identifies policy issues which apply to the whole site. It aggregates sites across all ads from all advertisers and regularly crawls them, building a repository of information that’s constantly improving as new scams and new sites are examined. We store the content of advertised sites and use both machine learning models and a rules engine to analyze the sites. The magic of the site review system is it understands the structure of language on webpages in order to classify the content of sites. Site review will determine whether or not an entire site should be disabled, which would prevent any ads leading to that site showing from any account. When the automated system isn’t able to determine the outcome with a high degree of confidence, we send it to a real person to make a decision. When a site is disabled, we tell the advertiser that it’s in violation of “Site Policy.”

Account Review
An account is one particular advertiser’s collection of ads, plus the advertiser’s selections for targeting and bidding on those ads. An account may have many ads which may point to several different sites, for example. The account review system constantly evaluates individual advertiser accounts to determine if the whole account should be inspected and shut down for policy violations. This system “listens” to a variety of signals, such as ads and keywords submitted by the advertiser, budget changes, the advertiser’s address and phone number, the advertiser’s IP address, disabled sites connected to this account, and disapproved ads. The system constantly re-evaluates all accounts, incorporating new data. For example, if an advertiser logs in from a new IP address, the account is re-evaluated to determine if that new signal suggests we should take a closer look at the content of the advertiser’s account. If the account review system determines that there is something suspect about a particular account with a high degree of confidence, it automatically suspends the account. If the system isn’t sure, it stops the account from showing any ads at all and asks a real person to decide if the account should be suspended.

Even with all these systems and people working to stop bad ads, there still can be times when an ad slips through that we don’t want. There are many malicious players who are very persistent—they seek to abuse Google’s advertising system in order to take advantage of our users. When we shut down a thousand accounts, they create two thousand more using different patterns. It’s a never-ending game of cat and mouse.

We’ve put a great deal of effort and expense into building these systems because Google’s long-term success is based on the trust of people who use our products. I’ve focused my time and energy in this area for many years. I find it inspiring to fight the good fight, to focus on the user, and do everything we can to help prevent bad ads from running. I’ll continue to post here from time to time with additional thoughts and greater information about how we make ads safer by detecting and removing scam ads.

全方位解读 Google 拆股

谷奥——探寻谷歌的奥秘

via 全方位解读 Google 拆股.

在昨天举行的2012年第一季度Google财报会议上,Google宣布拆股,这个举动非常奇怪,大家脑海里一定充满了各种问号,尤其是对我们这些对股票半懂不懂的人来说,下面就是来自SAI的全方位解读,给你恍然一个大明白。

问:如果我买了股票,这次拆股是如何做的?

答:一只股票被拆成俩,就是1分2。比如你在GOOG股票价值600美元一股的时候买了1000股,那么现在你就有了2000股每股价值300美元的股票了。新拆分出来的股票称为C级股票,它们是没有投票权的。

问:为何我看Google的官方文件里称这一举动为分红而非拆股?

答:因为这个方法有点像是分红──股东们获得了新的股票。但其实这种说法是有误导性的,尤其是在股东们一直期盼着真正的分红到来之时。

问:新拆分出来的C级股票跟以前的股票是独立的?

答:没错,它们将启用新的股票代码而非GOOG来进行交易。

问:之前还有哪个科技公司这么干过吗?

答:确实很稀少,不过对媒体公司来说到是很平常。比如Comcast就有两个等级的股票在交易,A级用CMCSA交易,每股占有0.1373投票权。而A特别级股票则使用CMCSK代码交易,没有投票权。CMSCK的交易稍微有些优惠,因为没有投票权。

问:这么说Google新拆分出的无投票权的股票也会有优惠了?

答:投资者们都是这么想的,是的。

问:那就是说我的股票拆分完之后反到没之前值钱了?

答:有可能,尽管这个举动如果使得A级股票上涨的话你还可以受益。但在此之后,两个股票很可能或多或少的捆绑在一起,价格上下浮动的差不多,当然在一天里还是会有变化的。不过投资者们似乎不喜欢Google的这个举动,所以今天GOOG下跌了4%,比大盘还惨一点。

问:最大的问题,Google干嘛要拆股?

答:最简单的说就是三驾马车(Eric Schmidt、Larry Page、Sergey Brin)要确认自己在未来很长一段时间里都对公司有绝对的控制权,他们不想落得YAHOO那样的下场。

问:现在他们不是一直就有控制权的吗?

答:没错,他们和其他一些高管也拥有三级和B级股票,但每只A级股票拥有10个投票权,这些股票是不公开发行的。他们现在加在一起拥有66%的投票权。

问:那他们还拆股?

答:因为随着公司的发展,接收更多的员工,进行更多是收购,三驾马车手里的A级股票就会逐渐被稀释。如果加上他们还要出售自己手里的股票的话,那就更快了。

问:那Google干嘛现在拆股?

答:不太明确。Larry Page说公司在未来不会做大型收购,尽管Google手里还有500亿现金可以用于投资。也许他们只是对当下YAHOO糟糕的状况给吓到了,或者他们也希望像Facebook创始人Mark Zuckerberg那样在IPO之后依然有绝对的投票权。

问:那就是说,投资Google的人必须信赖这哥儿仨喽?

答:没错,这正是他们所希望的。

Sergey Brin 为前几天自己抨击 Apple 和 Facebook 的言论做出解释

谷奥——探寻谷歌的奥秘

via Sergey Brin 为前几天自己抨击 Apple 和 Facebook 的言论做出解释.

大嘴Sergey前两天接受了卫报的采访,针对互联网开放性发表了一番自己的言论,引来了不少反对的声音。今天,不怎么玩社交网络的Sergey Brin却出人意料的利用Google+平台发了一篇文章,对自己的某些观点进行了澄清。

Brin首先继续表达了互联网开放性的重要性,他称互联网是在过去1/4世纪里推动世界发展的最强大力量,所以的那股卫报想就互联网自由性对他进行访谈的时候,他就决定一定要参加。尽管文章读起来很不错,但分散了Brin的核心原则,所以想借此机会澄清一下。

他说目前对互联网自由的最大威胁还是来自于政府对政治异议的过滤,这个问题比他想象中的要严重的多。包括美国在内的一些国家都在试图部署类似的技术来打击盗版和其它恶劣问题,Brin认为这些做法都有误导性切十分危险。

然后另外一个话题是说数字生态系统不如互联网开放,他认为这导致了自己的观点被误解。所以要澄清的是,Brin并未说这种不开放的生态系统已经严重到要跟政府过滤相提并论的程度上,另外自己对Apple和Facebook两家公司都十分敬佩。

对比自己在90年代建立Google时期,现在要做互联网会遇到很多新的门槛和关卡,如果你对这个问题感兴趣可以看看Jonathan Zittrain的http://futureoftheinternet.org/网站。
