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

3D printing continues to be a global spectacle in 2014, making appearances from Las Vegas during International CES and Barcelona during Mobile World Congress. With the 3D printing industry predicted to reach $10.8 billion by 2021, many are asking how it will change the future of the consumer landscape, much like MP3 players and iPods transformed the music industry. While the answers may not be obvious, there are a number of ways 3D printing will impact the daily lives of consumers in years to come. Opening the door to customization A major appeal to everyday consumers is how 3D printing opens the entryway to customization. From custom jewelry to food, the possibilities when using a 3D printer are endless. As 3D printers become more accessible over time, so will the ability to print items that are extremely personalized and tailored to each user. If we think about most of the products we buy, they are commoditized in some way for the average person; jeans are a certain length and cabinet handles come in standardized sizes. 3D printing allows consumers to create items exactly the way they need or want them - ultimately, letting customers set their own parameters. Companies like Nokia and New Balance, for example, have taken to the 3D printing trend and now offer online services where consumers can customize their own 3D printed cell phone case or sneakers, respectively.
