For all its success, Google's famous Page Rank algorithm has never understood a word of the billions of Web pages it has directed people to over the years. That's why in 2010 Google acquired Metaweb, a company building a database intended to give computers the ability to understand the world. Two years later the company's technology resurfaced as the Knowledge Graph (see "Corliss Tech Review Group: http://thecorlissreviewgroup.com/"). John Giannandrea, vice president of engineering at Google and a Metaweb cofounder, says that will lead to Google's future products being able to truly understand the people who use them and the things they care about. He told MIT Technology Review's Tom Simonite how a data store designed to link together all the knowledge on Earth might do that. What is the Knowledge Graph? It's a distillation of what Google knows about the world. An analogy I often use is maps. For a maps product you have to build a database of the real world and know there are things called streets, rivers, and countries in the physical world. That's creating a symbolic structure for the physical world; the Knowledge Graph does that for the world of ideas and common sense. We have entities in the knowledge graph for foods, recipes, products, ideas in philosophy or history, and famous people. We can have relationships between them, so we can say these two people are married or this place is in this country or we can say this movie is related to this person. How does that make a difference to Google's Web search? We've gone up a level from just talking about the words to talking about what the thing actually is. In crawling and indexing documents we can now have an understanding of what the document is about. If the docum

If you are a gadget enthusiast and aching to have your hands on Galaxy S5 or you just cannot since you have your Galaxy S4 from the previous year, you have a way to work it out. Consider trading your device with your carrier for a credit to your new phone. To get the most of your device, you can sell your phone, which you have lots of options. Here are some of them: EBay EBay provides you a marketplace for your items where predictability is less. Auctions can give you more or less earnings. Posting and managing items for sale are quite tedious until eBay introduced My Gadgets which will help you create a listing. You may list what you own and My Gadget will tell you how you can make based on eBay price trends if you sell it. EBay may not be the best choice for making more money with regard to selling your handsets. But it is usually a site where you can locate items which are extremely low or high demand or those which are difficult to find. Amazon Amazon is one of the most convenient ways to sell your old phone with some drawbacks. Find your device on Amazon, click the "Sell on Amazon" button and provide details.

Always Online The Anqor itself is fairly straightforward, as a device. It's about the size of a novelty paperback you get as a gift, and relatively light, although that's just the prototype; the end goal device is roughly the size of an iPhone. And it works relatively simply, as well; it connects to a 3G or 4G network in the area you're in, connects to up to ten of the devices you have handy, and we're off to the races. It's how it connects that's more interesting. SIMulated Card As we all know, to access a local mobile network, you need a SIM card, which is profoundly annoying. What the Anqor does is determine where you are, riffle through the company's library of SIM cards, upload the profile, and you're done. The tradeoff, of course, is that this doesn't come cheap. Global travelers looking for this convenience will be paying roughly $52 a month for the library, although you can pause a subscription at any time, and for just one country, it'll be a more reasonable $16 a month. Online Anywhere If you're a world traveler, you know from experience that you'll be running around juggling SIM cards anyway, so you may as well clean some of the clutter out of your life. And, if you never leave the country but your job requires constant Internet access, this might be worth it as well. The device, without data plan, will start at around $270 if you get in early on the Kickstarter.

It's a truth as universal as it is annoying; if you want all your devices to work with a specific keyboard, well, you'll probably need either one for each, sign on for precisely one device ecosystem, or get used to swiping in words. Travelers in particular are driven insane by this problem, so Logitech decided, quite cleverly, to solve it with the K480. Swiss Army Keyboard There are two problems with modern portable keyboards. The first is, as we noted, device compatibility. Ask anybody who's had to install drivers just to get a basic keyboard to work, the various device ecosystems out there don't play well with each other and seemingly want to drive you insane. Logitech solves this with some clever design. You can switch between three different places to send your words, so that regardless of whether you're all Apple, or a mix of Apple, Chrome, and Windows, you'll be able to use the keyboard and get the point across. Basically, if it uses Bluetooth, you're all set to type. At The Trough The second problem is keeping all your stuff organized; you've got your phone over here, your tablet over there, and your laptop in front of you… and many keyboards want to be docked solely at your tablet. How does Logitech solve this? Simple: It puts a trough at the top of the keyboard that can easily be used to stand up both your tablet and your phone, and to type away at both of them with ease. A Keyboard For The Multitasker Multitasking, or at least sorting through your various tasks properly, can be a profoundly annoying experience, and Logitech deserves credit for looking at how we actually use our gadgets and creating a keyboard that fits in with them. If that's something you need, it starts at just $50.
