Pulling the plug: saving energy

2008-05-15T22:55:17+02:00

In the previous year (until October 2007) my electricity consumption was 3,062 kwH. Since then I replaced all lamps with the low energy variant, and pull the plug on any electrical device I don't use. The projected consumption for this...



Weblog conversations: the big one

2008-05-15T21:34:52+02:00

The above picture depicts a "weblog conversation" in a certain community (see Lilia's overview for more and background). To somewhat appreciate the picture (called the "big one" by Lilia), if that is possible, the following information might be useful. Each...



That's not machine learning

2008-05-08T22:16:31+02:00

Yesterday, I gave a talk on educational data mining at the University of Amsterdam (my previous employer). The talk was about how I approach the very difficult issue of trying to understand what learners are doing in learning environments. During...



Workshop: Knowledge acquisition from the social web

2008-05-02T22:36:02+02:00

Some might be interested in a workshop on Knowledge acquisition from the social web. The workshop is part of Triple-I and located in Graz (Austria) in early September. Graz is a rather nice city, which I visited once ten years...



Conferences and their location

2008-04-17T22:19:01+02:00

A little food for thought. Let us suppose you are a scientist and have written a conference paper. Two conferences would possibly accept the paper. They take place around the same time, one at an exotic location you always wanted...



ADML workshop on Educational Data Mining

2007-09-30T23:31:36+02:00

Last week I was in Crete, Sissi to be precise, to present our work on chat analysis at the ADML workshop (Applying Data Mining Techniques to e-Learning) part of EC-TEL (European Conference on Technology Enhanced Learning). Crete: here we come...



Weblog data as art

2007-08-24T23:21:50+02:00

There are days one feels like winning the lottery. I discovered Lattice Uncertainty Visualization. This may not sound too appealing to many, but there are some very neat ideas about the visualisation of uncertainty (probabilities) in large data sets, particularly...



Weblog conversations and self-linking visualised

2007-08-15T14:04:49+02:00

Lilia is taking another look at weblog conversations (and I am too). Her posts so far: Weblog conversations revisited: an introduction Weblog conversations revisited: is there more than one? A weblog conversation is a set of linked posts. The most...



Avatars in learning environments

2007-08-07T21:19:28+02:00

A view months ago I posted on the use of avatars in learning environments. Since then we have worked out the idea and written a paper on it. Mauro Cherubini neatly summarised the idea in the paper on his weblog:The...



Weblog self-linking visualised

2007-08-04T23:20:11+02:00

A short post about the visualisation of self-linking in weblogs. The idea for having a look at self-linking behaviour is due to Lilia. An interesting property of self-linking is that there is only one dimension: time. And, unfortunately, visualisations of...
