The Bill & Melinda Gates Foundation, the world's largest philanthropy, and the foundation associated with Pearson, the giant textbook and school technology company, announced a partnership on Wednesday to create online reading and math courses aligned with the new academic standards that some 40 states have adopted in recent months.

Por qué usar Data mining?

According to Eva Tardos, Jacob Gould Schurman Professor of Computer Science at Cornell University, the researchers' paper "is more the beginning of research than a definitive result or end product." The researchers' models make several simplifying assumptions - including the number of competitors - that make the math easier but limit their applicability. Nonetheless, "just raising the questions is an important step forward," Tardos says.

Hace Estadísticas de tu Cuenta.

De hecho cualquier persona puede poner el nombre de otra y observar las estadísticas de comportamiento de esa otra persona. Es por tanto, una herramienta de doble filo, permite comparar tu actividad con la de otros, pero por otra parte están controlando a qué horarios te conectas, a quien retuiteas, cuales son las palabras que más utilizas, etc. A mí personalmente me ha sorprendido mis propias acciones. A veces piensas que vas en una dirección y sin embargo estás performando otra. Si alguna persona lo prueba, me gustaría saber su opinión. Saludos

And I'm saying the semantic web won't work. Can't work.

generating word clouds, interesting as a game, as analysis can be very simple, depending on what you want to search.

You know your data is big - you found Hadoop. What implications must you consider when working at this scale? This lecture addresses common challenges and general best practices for scaling with your data.

Have been listening to a Dave Snowden podcast of a "101 organic KM course". Amongst many familiar themes is the mention of the pitfalls of too much transparency hurting innovation.

After visualizing chat room dialogue earlier this week, I thought it might be neat to try and visualize some Twitter dialogue from the #LAK11 course.  For some reason I thought it would be simple to extract tweets from Twitter for analysis.  It wasn't!  So if you happen to know an easier way please leave a comment.

The majority of the information that we use in our daily lives is "dumb", or unconnected. The next step is "linked data", or data that talks to each other.

The availability of new sets of data has changed the way we live our lives: here are 10 examples of data which have changed everything from how we assess wars to how companies deliver milk.

Goodhart's law states that once a social or economic indicator or other surrogate measure is made a target for the purpose of conducting social or economic policy, then it will lose the information content that would qualify it to play such a role.

Is Goodhart's law relevant when thinking about Learning Analytics

My take on this week's readings and webinar

Hans Rosling's famous lectures combine enormous quantities of public data with a sport's commentator's style to reveal the story of the world's past, present and future development. Now he explores stats in a way he has never done before - using augmented reality animation. In this spectacular section of 'The Joy of Stats' he tells the story of the world in 200 countries over 200 years using 120,000 numbers - in just four minutes. Plotting life expectancy against income for every country since 1810, Hans shows how the world we live in is radically different from the world most of us imagine.
