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 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.

via 全方位解读 Google 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。






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。

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。




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的网站。
