Big Data, Trying to Build Better Workers

Art Jones

See on Scoop.itPeople Really Matter

Work history does not matter as much as we think it does, and bosses matter more — these are findings from an emerging field called work-force science.

Art Jones‘s insight:

Work-force science, in short, is what happens when Big Data meets H.R.

The new discipline has its champions. “This is absolutely the way forward,” says Peter Cappelli, director of the Center for Human Resources at the Wharton School of the University of Pennsylvania. “Most companies have been flying completely blind.”

Big Data — Analyses That Will Help Your Brand Go Viral


Why do some news items go viral and others don’t? Why are people willing to share certain stories with their friends instead of others? While we may be led to believe that interesting products are key to such viral spread, nothing could be farther from the truth. Enter Big Data analysis…

Analyses of data by Jonah Berger (Marketing professor at the Wharton School and author of the New York Times bestseller Contagious: Why Things Catch On) and his colleague shed more light on why things go viral. They investigated word-of-mouth data for over 10,000 products and brands and over 7,000 pieces of online content and here’s what they came up with…

GE wants to use artificial intelligence to predict the future of hospitals


Around the world, the health care system is rife with inefficiencies, and General Electric (s ge) thinks it can help solve the problem using data. Only it’s not talking about bureaucrats looking at reports: GE has built an artificial intelligence system called Corvix that uses historical data to predict the future, including everything from how diseases will spread to the cities where hospitals will be needed the most.

It might sound futuristic, but the techniques behind Corvix have actually been around for a while. The platform uses agent-based modeling to build, essentially, a reasonable facsimile of some sort of complex system and then simulate its evolution over time. The “agents” represent the atomic units of those systems, such as individual people in the case of human populations or perhaps cells in the case of a biological simulation. They act according to a set of rules in any given situation, which…

Archivos cerrados: estas herramientas de extracción te facilitarán la vida

Noches de Media

Sin título 1Por Tatta25

Una de las primeras lecciones aprendidas del Mooc de Periodismo de Datos, dictado por Sandra Crucianelli en el Knight Center, es la extracción de datos en archivos cerrados.

La maestra argentina nos enseñó a los participantes varias herramientas gratuitas de las que disponemos en la web los periodistas interesados en trabajar con datos atrapados en formato PDF. Algunas tienen más funcionalidades que otras, pero a ensayo y error se encontrarán las que más se ajusten a nuestras necesidades de trabajo. Por ejemplo, algunas ofrecen la opción de sólo extraer los datos de la primera página o de archivos con determinado peso.
