  • Remember Goodhart's Law - any statistical instrument used for policy looses all value, or loosely translated the minute a measure becomes a target it ceases to be a measure.

    Is Goodhart's law relevant when thinking about Learning Analytics

    How to create annotations in a Moodle discussion forum.
  • Dianne Rees on 15 Jan 11
     
    Can also probably use Diigo to do something similar (e.g., via public sticky notes). Always wonder if that's rude though...you don't give the Moodling person (who might not be using Diigo or the annotation tool) the oppt to respond.

  • This simple change made Google's ad marketplace much more efficient than Overture's. Notice that the algorithm itself is quite simple; it is the addition of the new data that made the difference.
  • Of course, you have to be judicious in your choice of the data to add to your data set.
  • Tony Searl on 17 Jan 11
     
    But the bigger point is, adding more, independent data usually beats out designing ever-better algorithms to analyze an existing data set. I'm often suprised that many people in the business, and even in academia, don't realize this.

    20 years ago, Tim Berners-Lee invented the World Wide Web. For his next project, he's building a web for open, linked data that could do for numbers what the Web did for words, pictures, video: unlock our data and reframe the way we use it together.

shared by hansdezwart on 23 Jan 11 - Cached
  • Non requirements Discussions on Hypertext have sometimes tackled the problem of copyright enforcement and data security. These are of secondary importance at CERN, where information exchange is still more important than secrecy. Authorisation and accounting systems for hypertext could conceivably be designed which are very sophisticated, but they are not proposed here. In cases where reference must be made to data which is in fact protected, existing file protection systems should be sufficient.
  • In a complex place like CERN, it's not always obvious how to divide people into groups. Imagine making a large three-dimensional model, with people represented by little spheres, and strings between people who have something in common at work.
  • hansdezwart on 23 Jan 11
     
    This document was an attempt to persuade CERN management that a global hypertext system was in CERN's interests. Note that the only name I had for it at this time was "Mesh" -- I decided on "World Wide Web" when writing the code in 1990.
