Partnering with GE on clean energy

Today we announced that we're <a href="http://services.google.com/blog_resources/google_org_ge_energyfactsheet.pdf" id="d1_0" title="joining forces">joining forces</a> (PDF file) with GE to use technology, information and corporate resources to drive the changes necessary to empower consumers with better energy choices. We will focus on improving power generation, transmission and distribution – a combination of technologies that could be known as the "<a href="http://en.wikipedia.org/wiki/Smart_grid" id="zkx7." title="smart grid">smart grid</a>." (It would be fair to refer to electricity technologies in common use today as a "grid of only average intelligence.") The existing U.S. infrastructure has not kept pace with the digital economy and the hundreds of technology opportunities that are ready for market. In fact, the way we generate and distribute electricity today is essentially the same as when Thomas Edison built the first <a href="http://en.wikipedia.org/wiki/Thomas_Edison#Electric_power_distribution" id="ir8i" title="power plant">power plant</a> well over one hundred years ago. Americans should have the choice to drive more fuel efficient cars – or even electric cars - and manage their home energy use to reduce costs, and buy power from cleaner sources, or even generate their own power for sale to the grid. We all receive an electricity bill once a month that encourages little except prompt payment. What if, instead, we had access to real-time information about home energy use? What if our flat screen TVs, electronic equipment, lights and appliances were programmed to automatically adjust to save money and cut energy use? What if we could push a button and switch the source of our homes' electricity from fossil fuels to renewable energy? What if the car sitting in our garage ran on electricity – the equivalent of $1 per gallon gasoline – and was programmed to charge at night when electricity is cheapest? This vision is what unites Google and GE. We’ll start by working together in Washington, D.C. to mount a major policy effort to enable large-scale deployment of renewable energy generation in the United States. We’ll also work on development and deployment of the “smart” electricity grid that will empower consumers, utilities, and technology innovators to manage electricity more efficiently and lower their carbon footprint. Finally, we'll collaborate on advanced energy technologies, including technologies to enable the large-scale integration of <a href="http://www.google.org/recharge/" id="ft.c" title="plug-in vehicles">plug-in vehicles</a> into the grid and new geothermal energy technologies known as <a href="http://www.google.org/egs/" id="qcx6" title="enhanced geothermal systems">enhanced geothermal systems</a> (EGS). <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjy4qMKIeCLX3x4MU6AIT7-7PELlfHzPQeg5vMng08SPQGf6YT_b6UoEAGjaYFahCXVIndjHNKpp9MBcwKWsucktPdEjp9CHI4A9FWuyjx4Hz2NAJku_iDk5_gRBqgqpapwq1dVs5ZRJ5rF/s1600-h/IMG_1127.JPG" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" id="BLOGGER_PHOTO_ID_5247089224660681378" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjy4qMKIeCLX3x4MU6AIT7-7PELlfHzPQeg5vMng08SPQGf6YT_b6UoEAGjaYFahCXVIndjHNKpp9MBcwKWsucktPdEjp9CHI4A9FWuyjx4Hz2NAJku_iDk5_gRBqgqpapwq1dVs5ZRJ5rF/s320/IMG_1127.JPG" style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" /></a> <div style="text-align: center;">Eric Schmidt with GE's CEO Jeff Immelt at Google's Zeitgeist conference </div> Update: Here's <a href="http://www.youtube.com/watch?v=hsf6t5hSWDM">the video</a> of Eric Schmidt and Jeff Immelt's talk at Zeitgeist '08.

What to do if you can't access your webmail

This post is the latest in an ongoing <a href="http://googleblog.blogspot.com/search/label/security" id="tkbs" title="series">series</a> on how to stay safe online. - Ed. We know how important webmail is to the people who use it regularly, since (of course) we use it ourselves at Google. So we know that not being able to access a webmail account -- no matter what the reason, or how long it lasts -- can be frustrating at the very least. Sometimes interruptions are caused by technical issues with your mail program or your Internet connection. More often, they're account-related. When it comes to Gmail specifically, there are a couple of things that might cause account-related interruptions in access: a lost or forgotten password, <a href="http://mail.google.com/support/bin/answer.py?answer=43692" id="v4u8" style="background-color: rgb(255, 255, 255);" title="unusual activity">unusual activity</a> that triggers the safety measures designed to keep accounts from being compromised, or, in the worst case, someone has stolen your login info and changed it. Most of the questions we get about account interruptions are the result of lost or forgotten passwords and as such are relatively easy to fix (more below). But no matter what their origin, we take these issues very seriously. Of course, there are certain cases where our options are limited -- we don't ask for much personal information when you sign up for Gmail, which can sometimes make it difficult to prove ownership of an account and trigger the recovery process. Still, there are some simple steps you can take to ensure that your account stays in your hands, and to greatly improve the chances of <a href="http://mail.google.com/support/bin/answer.py?answer=46346&fpUrl=https%3A%2F%2Fwww.google.com%2Faccounts%2FForgotPasswd%3FfpOnly%3D1%26continue%3Dhttps%253A%252F%252Fmail.google.com%252Fmail%252F%253Fhl%253Den%2526tab%253Dwm%2526nsr%253D1%2526ui%253Dhtml%2526zy%253Dl%26service%3Dmail%26hl%3Den&fuUrl=https%3A%2F%2Fwww.google.com%2Faccounts%2FForgotPasswd%3FfuOnly%3D1%26continue%3Dhttps%253A%252F%252Fmail.google.com%252Fmail%252F%253Fhl%253Den%2526tab%253Dwm%2526nsr%253D1%2526ui%253Dhtml%2526zy%253Dl%26service%3Dmail%26hl%3Den&hl=en" id="fzvf" title="getting it back">regaining access</a> if you have any problems: <ul><li>Don't share your Gmail password with anyone.

When you sign up for Gmail, we'll ask you for a secondary email address and then email a verification number to that account. This number is the best way to prove ownership of your account, so be sure to hang on to it.</li></ul><ul><li>If you aren't able to access your account, try <a href="https://www.google.com/accounts/ForgotPasswd?service=mail&fpOnly=1&dEM=" id="om:l" title="resetting your password">resetting your password</a>.

We recently launched an account-recovery form in our help center that can drastically reduce the amount of time it takes to verify ownership of an account and restore access. If you have the information necessary to prove ownership -- such as the verification code for the account -- this new process can help our support team restore access within a matter of hours.</li></ul>Again, we're always working on ways to help you keep your account secure and to stay safe online.

Let's hear it for Google scholarship winners

Across the world, the participation of women and minorities in computer science is at an all-time low. According to studies conducted by the National Science Foundation, the annual graduation rate for women in computer science is just 22%, just 6.5% for Hispanic students, 4.8% for African American students, and under 1% for American Indian students. As part of our global effort to increase diversity in our industry, we have created scholarship programs with the <a href="http://www.uncf.org/forstudents/scholarDetailSGA.asp?id=161" title="United Negro College Fund">United Negro College Fund</a>, the <a href="http://scholarships.hispanicfund.org/applications/subsectionID.1,pageID.123/default.asp">Hispanic College Fund</a> and the <a href="http://www.aises.org/Programs/ScholarshipsandInternships/Scholarships" id="vrrp" title="American Indian Science & Engineering Society">American Indian Science & Engineering Society</a>. Each of these programs is meant to encourage students to excel in their studies and become active role models and leaders. It's our hope that these programs also help dismantle barriers that keep women and minorities from entering computing and technology fields. (<a href="http://www.google.com/jobs/scholarships" id="brc4">Read more</a> about Google's scholarship programs.) Now comes the really fun part: announcing the 2008 winners. Please join us in congratulating the 42 students who have been recognized for their outstanding academic and leadership accomplishments in the computer science field. Each of these students will receive a $10,000 academic scholarship from Google, as well as an invitation to attend the all-expenses-paid <a href="http://www.youtube.com/watch?v=kDL6GXlZkh0" id="i5sa" title="Annual Google Scholars' Retreat">Annual Google Scholars' Retreat</a> held each Spring at the <a href="http://maps.google.com/maps?f=q&hl=en&q=1600+Amphitheatre+Pkwy,+Mountain+View,+California+94043,+United+States&sll=37.547027,-122.055359&sspn=0.297792,0.617981&ie=UTF8&cd=1&geocode=FfAHOwId_yC5-A&ll=37.42423,-122.085121&spn=0.009321,0.019312&z=16&iwloc=addr" id="b38." title="Googleplex">Googleplex</a> in Mountain View.

The future of online video

The Internet has had an enormous impact on people's lives around the world in the ten years since Google's founding. It has changed politics, entertainment, culture, business, health care, the environment and just about every other topic you can think of. Which got us to thinking, what's going to happen in the next ten years? How will this phenomenal technology evolve, how will we adapt, and (more importantly) how will it adapt to us? We asked ten of our top experts this very question, and during September (our 10th anniversary month) we are presenting <a href="http://googleblog.blogspot.com/search/label/Google%20at%2010">their responses</a>. As computer scientist Alan Kay has famously observed, the best way to predict the future is to invent it, so we will be doing our best to make good on our experts' words every day. - Karen Wickre and Alan Eagle, series editors Ten years ago the world of online video was little more than an idea. It was used mostly by professionals like doctors or lawyers in limited and closed settings. Connections were slow, bandwidth was limited, and video gear was expensive and bulky. There were many false starts and outlandish promises over the years about the emergence of online video. It was really the dynamic growth of the Internet (in terms of adoption, speed and ubiquity) that helped to spur the idea that online video - millions of people around the world shooting it, uploading it, viewing it via broadband - was even possible. Today, there are thousands of different video sites and services. In fact it's getting to be unusual not to find a video component on a news, entertainment or information website. And in less than three years, YouTube has united hundreds of millions of people who create, share, and watch video online. What used to be a gap between "professional" entertainment companies and home movie buffs has disappeared. Everyone from major broadcasters and networks to vloggers and grandmas are taking to video to capture events, memories, stories, and much more in real time. Today, 13 hours of video are uploaded to YouTube every minute, and we believe the volume will continue to grow exponentially. Our goal is to allow every person on the planet to participate by making the upload process as simple as placing a phone call. This new video content will be available on any screen - in your living room, or on your device in your pocket. YouTube and other sites will bring together all the diverse media which matters to you, from videos of family and friends to news, music, sports, cooking and much, much more. In ten years, we believe that online video broadcasting will be the most ubiquitous and accessible form of communication. The tools for video recording will continue to become smaller and more affordable. Personal media devices will be universal and interconnected. Even more people will have the opportunity to record and share even more video with a small group of friends or everyone around the world. Over the next decade, people will be at the center of their video and media experience. More and more consumers will become creators. We will continue to help give people unlimited options and access to information, and the world will be a smaller place. Posted by Chad Hurley, CEO and Co-Founder, YouTube

Search evaluation at Google

<a href="http://googleblog.blogspot.com/search/label/search%20quality" id="so8g" title="This series">This series</a> of posts has described Google's search quality efforts in areas such as ranking and search UI. Now I'll describe search evaluation. Simply put, search evaluation is the process of measuring the quality of our search results and our users' experience with search. Let me introduce myself. I'm Scott Huffman, an engineering director responsible for leading search evaluation, working with a talented team of statisticians and software engineers. I've been here since 2005, and have been working on search in one form or another for the past fourteen years or so. When I'm interviewing folks interested in joining the search evaluation team, I often use this scenario to describe what we do: Imagine a Google ranking engineer bursts into your office. "I have a great idea for improving our search results!" she exclaims. "It's simple: Whenever a page's title starts with the letter T, move it up in the results three slots." This engineer comes armed with several example search queries where, lo and behold, this idea actually improves the results significantly. Now, you and I may think that this "letter T" hack is really a silly idea, but how can we know for sure? Search evaluation is charged with answering such questions. This hack hasn't really come up, but we are constantly evaluating everything, which can include: <div id="gd2q"> - proposed improvements to segmentation of Chinese queries </div> <div id="gd2q0"> - new approaches to fight spam </div> <div id="gd2q1"> - techniques for improving how we handle compound Swedish words </div> <div id="gd2q1"> - changes to how we handle links and anchortext </div> <div id="ucyj"> - and everything in between As Udi mentioned in his <a href="http://googleblog.blogspot.com/2008/05/introduction-to-google-search-quality.html" id="xxu8" title="initial post">initial post</a> on search quality, in 2007 we launched over 450 improvements to Google search, and every one of them went through a comprehensive evaluation process. </div> <div id="yygm12"> </div> <div id="yygm14"> Not surprisingly, we take search evaluation very seriously. Precise evaluation enables our teams to know "which way is up". One of our tenets in search quality is to be very data-driven in our decision-making. We try hard not to rely on anecdotal examples, which are often misleading in search (where decisions can affect hundreds of millions of queries a day). Meticulous, statistically-meaningful evaluation gives us the data we need to make real search improvements. Evaluating search is difficult for several reasons. <ul id="yygm20"><li id="yygm24" style="margin-left: 15px;"> First, understanding what a user really wants when they type a query -- the query's "intent" -- can be very difficult. For highly navigational queries like [ebay] or [orbitz], we can guess that most users want to navigate to the respective sites. But how about [olympics]? Does the user want news, medal counts from the recent Beijing games, the IOC's homepage, historical information about the games, ... ? This same exact question, of course, is faced by our ranking and search UI teams. Evaluation is the other side of that coin. </li><li id="yygm27" style="margin-left: 15px;"> Second, comparing the quality of search engines (whether Google versus our competitors, Google versus Google a month ago, or Google versus Google plus the "letter T" hack) is never black and white. It's essentially impossible to make a change that is 100% positive in all situations; with any algorithmic change you make to search, many searches will get better and some will get worse. </li><li id="yygm27" style="margin-left: 15px;"> Third, there are several dimensions to "good" results. Traditional search evaluation has focused on the relevance of the results, and of course that is our highest priority as well. But today's search-engine users expect more than just relevance. Are the results fresh and timely? Are they from authoritative sources? Are they comprehensive? Are they free of spam? Are their titles and snippets descriptive enough? Do they include additional UI elements a user might find helpful for the query (maps, images, query suggestions, etc.)? Our evaluations attempt to cover each of these dimensions where appropriate. </li><li id="yygm30" style="margin-left: 15px;"> Fourth, evaluating Google search quality requires covering an enormous breadth. We cover over a hundred locales (country/language pairs) with in-depth evaluation. Beyond locales, we support search quality teams working on many different kinds of queries and features. For example, we explicitly measure the quality of Google's spelling suggestions, universal search results, image and video searches, related query suggestions, stock oneboxes, and many, many more. </li></ul> </div> To get at these issues, we employ a variety of evaluation methods and data sources: <ul><li> Human evaluators. Google makes use of evaluators in many countries and languages. These evaluators are carefully trained and are asked to evaluate the quality of search results in several different ways. We sometimes show evaluators whole result sets by themselves or "side by side" with alternatives; in other cases, we show evaluators a single result at a time for a query and ask them to rate its quality along various dimensions. </li><li> Live traffic experiments. We also make use of experiments, in which small fractions of queries are shown results from alternative search approaches. Ben Gomes talked about how we make use of these <a href="http://googleblog.blogspot.com/2008/08/search-experiments-large-and-small.html" id="leq_" title="experiments for testing search UI elements">experiments for testing search UI elements</a> in his previous post. With these experiments, we are able to see real users' reactions (clicks, etc.) to alternative results. </li></ul> Clearly, we can never measure anything close to all the queries Google will get in the future. Every day, in fact, Google gets many millions of queries that we have never seen before, and will never see again. Therefore, we measure statistically, over representative samples of the query-stream. The "letter T" hack probably does improve a few queries, but over a representative sample of queries it affects, I'm confident it would be a big loser. One of the key skills of our evaluation team is experimental design. For each proposed search improvement, we generate an experiment plan that will allow us to measure the key aspects of the change. Often, we use a combination of human and live traffic evaluation. For instance, consider a proposed improvement to Google's "related searches" feature to increase its coverage across several locales. Our experiment plan might include live traffic evaluation in which we show the updated related search suggestions to users and measure click-through rates in each locale and break these down by position of each related search suggestion. We might also include human evaluation, in which for a representative sample of queries in each locale, we ask evaluators to rate the appropriateness, usefulness, and relevance of each individual related search suggestion. Including both types of evaluation allows us to understand the overall behavioral impact on users (via the live traffic experiment), and measure the detailed quality of the suggestions in each locale along multiple dimensions (via the human evaluation experiment). Choosing an appropriate sample of queries to evaluate can be subtle. When evaluating a proposed search improvement, we consider not only whether a given query's results are changed by the proposal, but also how much impact the change is likely to have on users. For instance, a query whose first three results are changed is likely much higher impact than one for which results 9 and 10 are swapped. In Amit Singhal's <a href="http://googleblog.blogspot.com/2008/07/technologies-behind-google-ranking.html" id="n.lb" title="previous post on ranking">previous post on ranking</a>, he discussed synonyms. Recently, we evaluated a proposed update to make synonyms more aggressive in some cases. On a flat (non-impact-weighted) sample of affected queries, the change appeared to be quite positive. However, using an evaluation of an impact-weighted sample, we found that the change went much too far. For example, in Chinese, it synonymized "small" (小) and "big" (大)... not a good idea! We're serious about search evaluation because we are serious about giving you the highest quality search experience possible. Rather than guess at what will be useful, we use a careful data-driven approach to make sure our "great ideas" really are great for you. In this environment, the "letter T" hack never had a chance.

Alaska-bound!

As this post goes live, five Googlers are on their way to Barrow, Alaska, the northernmost inhabited location on the North American mainland. What brings us to such a far-off place? We're visiting three rural school districts to show teachers and students how <a href="http://earth.google.com/">Google Earth</a> and <a href="http://maps.google.com/">Maps</a> can be powerful tools in the classroom. There has been a lot of interest in the 49th state of late, but our trip has actually been months in the making. The idea for an educational outreach tour began when one active Geo developer, John Bailey of the University of Alaska Fairbanks (UAF), told us about his experiences teaching undergrads with Google Earth. We wanted to learn more and help spread the word on how educators are using these technologies, and knew we wouldn't find a better guide than the <a href="http://www.geographyua.org/">Geography Department at the University of Alaska</a>. In each town, we'll begin with a school-wide assembly with 9th-12th graders where our colleagues from UAF will explain our visit and help introduce Google's Geo tools, after which we'll inject some Googley fun into the mix with a trivia contest. Then we'll break into smaller groups where we'll focus on three classroom activities: First, we'll use Google Earth and image overlays to see how Alaska has changed over time. Then, we'll get out in the field on a geo-caching mini-adventure where students will learn how to upload GPS tracks.
