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

Protecting yourself against harmful and life threatening viruses, its best to choose the antivirus by brand name. But each Antivirus download that you can find on the internet is dependent on what is most important to the user in terms of variables. Some are more dedicated to filtering through malware and spyware; some systems pride themselves on being the most reliable, or adaptable to the constant change of cyberspace gunk that's floating around. So with all these choices, how're we supposed to know which program is suited to our professional needs? We hope to address those concerns and point the potential onlooker in the right direction for a potential download, or perhaps full-on purchase of the bundled software. For the moment we'll be looking at Avast! and AVG which are both free antivirus downloads available for your computer on reliable online websites. Avast! Free Antivirus Software: The Basics Chances are if you're looking to get in on the ground floor to check if Avast! is right for you, then you'll be looking into the coverage that the free antivirus download is going to offer. Avast! is ranked as one of the top antivirus programs in the market with 17% of users in the entire market share of protection services. Which is pretty far up there with McAfee, Bitdefender, and other potential competition. AVG Antivirus Software: The Basics In comparison to Avast! the folks at AVG are a little behind in their numbers at 170 million+ having entrusted their computer's health to the program. But the software itself is secure and accessible on their website. AVG have won an array of awards for their antivirus software, and can be considered a lively competitor to Avast! and other protection bundles.

It weighs just 34 grams, is 72 x 35 x 12 mm in size, and costs only the $39: The Google Chromecast looks and feels like a USB flash drive with a glandular problem. Cheap, easy to set up and even easier to use, there's really nothing to dislike about the Google streaming device, except for one thing: Canadian content (which we will get to in a moment). The Chromecast is so small that once it's plugged into an HDMI port in the back of a television set, there's almost no indication that it's a part of your home theatre setup. Only its power cord, which can either be plugged into a wall socket or available USB port, gives a hint that it's even there. Unlike other streaming media devices like the Apple TV or Roku 3, Google Chromecast doesn't come with a remote control, or in fact, any onboard applications or content. Everything, from setting up the device to watching a video from your personal media collection or browsing YouTube, is done through the use of apps on an Android phone or tablet, iOS device or via Google Chrome browser on a Chrome OS, Windows or Mac PC. No matter which device you use with the Chromecast, setup is a cinch. Simply power the device, plug it into an available television HDMI port and follow the Chromecast's onscreen prompts. The device will walk you through the process of connecting it to a Wi-Fi network, pairing with your choice of source device and downloading any available firmware updates. Even with the lousy Internet speeds I suffered while testing the hardware in rural southwestern Ontario I was setup and ready to start streaming content to my Chromecast in under 10 minutes.

Welcome to Gadget Review's new weekly app review column. We are starting out with iOS apps only, but in the future we will extend to other OSS ecosystems. If you have an app to recommend, please do so in the comments or via our social media channels. 1. Mynd Calendar apps have come and gone, and nothing has yet replaced the tried and true calendars from Google, Apple and Microsoft. Enter Mynd, an "intelligent mobile calendar" from Alminder Inc. This, loyal readers, is the game changer. 2. FTL: Faster Than Light Though more and more people are playing games on their iOS devices, most of those games are pretty basic and, for self-identifying gamers, extremely boring. If you've been looking for a real-deal game to sink your thumbs into, buckle up for Faster Than Light. 3. Sleep Cycle Alarm Clock In my humble opinion, the worst part of the day is setting an alarm for the next morning. But it doesn't have to be that way anymore, thanks to Sleep Cycle, an intelligent alarm clock from Northcube AB. 4. Data Count In an era of data caps, we could all use a tool to help us avoid the additional charges that accompany all those streaming overages. Data Count, from Creo, is just the ticket. 5. Monument Valley Sometimes, apps transcend ones and zeros. They usher in a new way of life, perhaps, or offer a major social improvement. And, in rare cases, they become true art. 6. Pinnacle Studio for iPhone Heres one for the pros. Or anyone who takes a lot of photos. Which is just about everyone with an iPhone.
