Robôs invadem as redações

Video

Um noticiário personalizado, no qual avatares apresentam atualizações de seus sites jornalísticos preferidos. Essa é a proposta da startup Guide. Demo acima. Ainda está num estágio embrionário. Impressiona pela dinâmica similar ao do telejornal, mas a apresentadora virtual tem o mesmo entusiamo da moça do GPS.

Não estranhe. Nos bastidores, os robôs já são aliados das empresas jornalísticas, dando uma força na estratégia digital. Garimpam dados e indicam caminhos, como determinar a frequência ideal de publicação de novos textos, o ritmo de mudança das notícias em destaque na página inicial, o horário mais propício para compartilhar conteúdo pelo Twitter…

autoeducação

From university classes via YouTube and startups like Udacity to the One Laptop Per Child (OLPC) project, there are more ways than ever for children to educate themselves, even in remote villages in Ethiopia. Despite the inevitable criticisms such efforts get both from within the education system and outside it, it’s part of a powerful and growing phenomenon.

[...] Udacity and the OLPC project are only two of the many startups and other ventures that are trying to change the way education occurs — not just in North America, but everywhere. There is also the Khan Academy, which started with Salman Khan using YouTube videos as a way of teaching his young niece about mathematics and now has delivered more than 200 million individual lessons. And there is Coursera, which is designed to allow any educational institution to offer online instruction. Although the latter ran into a brief regulatory roadblock in Minnesota, there are signs that these kinds of innovative efforts are being accepted: Udacity courses are now being approved for credit by some universities, including one in Colorado.

Whether it’s moribund educational institutions or governments or just bureaucratic red tape, what examples like these show is that the disruption of education continues whether such entities like it or not. Students will find a way to learn if they are given the opportunity, and technology and the social web are providing some powerful ways of doing that.

He was the guy who came up with the original method that Google eventually used to create their PageRank algorithm. His newest algorithm ranks people and their place in society by how they affect others through language. For example, if, in any given group there’s one guy who influences the others more strongly than anyone else, he tends to be the leader. This can be measured quantitatively. The schematic of how this works looks just like the schematic of how web pages are ranked. Whoever is linked and has more power over all of these trusted sites is who ends up at the top of the Google rankings. Same for people.

Christopher Steiner, autor do livro Automate This: How Algorithms Came to Rule Our World, explica à Fast Company a nova empreitada de Jon Kleinberg, professor de ciência da computação que desenvolveu um algoritmo para identificar os influenciadores em determinados grupos.
