Just wanted to mention that apriori is not the best choice, since it isn't particularly developed for stream data mining. In [1] you will find some recent approaches to stream rule mining. There is also some work in clustering analysis of stream data that might be interesting for the project. Jiang, N. and Gruenwald, L. 2006. Research issues in data stream association rule mining.

I think there can be a better way to do so :) Hey

But that's just because it's pretty much an NP-complete problem, right? I did some pruning last year when we built a computer AI for the orthello game. If I recall correctly it gave us like a 2-3 time speed up there ;-) But I can imagine that with this type of problem pruning can even be more rewarding, especially when working on the data set u described.

We are going to use an adaptive bucket size estimation based on the density of events. I think this would help out alot :) The bigger the timerange the lesser the errors.

The supermarket idea is a nice data mining example but is not fully comparable with event streams. Because you assume that a transaction occurs every 30 minutes it is possible that events of different tasks will occur in one transaction. I believe a better approach is to use instead algorithms for frequent episodes. I really like what you are doing with zeitgeist and certainly these kind of functionalities.

Codethink is not the only company working on Tracker. Codeminded AND Lanedo have core developers there too. Seif, why are you linking codethink.co.uk for Tracker?

Well done! This sort of thing is totally my definition of cool. Well, as cool as it gets in the Ubuntu world. Which is cool for me, but for most others probably incredibly boring haha That is awesome! Well done!
