Twitter’s Geography: Visualized and Explained. Twitter’s CEO Dick Costolo has called the popular microblogging service “the pulse of the planet.”

Twitter’s Geography: Visualized and Explained

With a little less than eight percent of the world’s population on Twitter, that pulse has room to grow. Nevertheless, recent big data research into the geography of the Twittersphere sheds light on where users tweet, with whom they tweet, and what information they share. The findings illustrate that Twitter helps people transcend geographic boundaries that restricted communication in a pre-digital age. A research team from the University of Illinois at Urbana-Champaign examined location data from the Twitter Decahose, which includes 10 percent of tweets sent on a given day.

The team examined more than 1.5 billion tweets sent from more than 71 million unique users over 39 days and documented its findings in a paper published online. Researchers dramatically expanded the number of located tweets through geocoding. Where Do People Tweet From? Who Do People Communicate With on Twitter? Introducing the Knowledge Graph: things, not strings. Cross-posted on the Inside Search Blog Search is a lot about discovery—the basic human need to learn and broaden your horizons.

Introducing the Knowledge Graph: things, not strings

But searching still requires a lot of hard work by you, the user. So today I’m really excited to launch the Knowledge Graph, which will help you discover new information quickly and easily. Take a query like [taj mahal]. For more than four decades, search has essentially been about matching keywords to queries. To a search engine the words [taj mahal] have been just that—two words. But we all know that [taj mahal] has a much richer meaning. The Knowledge Graph enables you to search for things, people or places that Google knows about—landmarks, celebrities, cities, sports teams, buildings, geographical features, movies, celestial objects, works of art and more—and instantly get information that’s relevant to your query.

Google’s Knowledge Graph isn’t just rooted in public sources such as Freebase, Wikipedia and the CIA World Factbook. 1. 2. Internet : 3 internautes sur 4 sur un réseau social. Par Emilien Ercolani, le 19 juillet 2012 15:39 Selon Médiamétrie, 77% des internautes sont inscrits sur au moins un réseau social. Les résultats de la dernière enquête Mediamétrie ne font que confirmer ce que tout le monde savait déjà : la quasi-totalité des internautes (99%) connait au moins un réseau social. 77% des internautes français sont d’ailleurs inscrits sur au moins l’un d’entre eux. Mais Mediamétrie souligne un élément important, à savoir la complémentarité des réseaux sociaux : « Les internautes ne s’inscrivent plus sur un mais sur plusieurs réseaux sociaux, selon ce qu’ils souhaitent y faire. Et ils y sont connectés à tout instant, en mobilité et même sur leur lieu de travail ».

Selon l’étude, Facebook est privilégié pour partager des expériences avec ses proches, Viadeo est consacré à la vie professionnelle et Twitter est avant tout utilisé pour partager des informations - de plus en plus exclusives - ou consulter des articles. How Big is the Internet? Nothing is free.

How Big is the Internet?

But my free water comes from the well behind my house. If I had a roof full of solar panels I wouldn't have to pay for electricity to pump it off the ground. Then I would be truly living off the grid. Taxes and Death are a part of life. But hey, why can't someone demand free internet or that at least my taxes covered it, or maybe all the advertising? Because, for all we know, they were subsidized by the government or banks with our pooled tax money or savings to provide a service, and for some companies it was phones, others Internet. If we each were born with our own IP and connected to each other with a rat's nest of cabling we would have a free monthly internet that was slow and awkward. Hal R. Varian. Hal R.
