The performance of online communities - An Empirical Investigation of Wikipedia

24 08 2010

I decided to upload my Diploma Thesis to scribd.com. Maybe some things are of value for students and other researchers.

who tweets about ... ? - revisited: twitter timeplot generator

08 08 2010

Last week i stumpled upon the awesome simile widgets (a spin off of the simile project at MIT) and after playing around with timeline and timeplot for a while I thougt about bringing my who tweets about fun-project to the next level.

I startet with a timeline of tweets but realized that this is getting overloaded quite fast. So I used timeplot and its ability to load timeline events to come up with the twitter timeplot generator.


e.g.: who tweets about garmz and when?(click on the dates to see the tweets)



Due to Twitters search api limitation (1500 tweets) this is of limited use with popular topics. So I looked for an alternative source of tweets and found twapperkeeper.com which offers a number of tweet-archives on various hashtags.

I adapted the code and came up with this visualization of the days after jackos death(I removed the tweets due to their enormous number):




any ideas for events to visualize in this manner?

You can try it here: Twitter Timeplot
