Last.fm Netzwerk visualisiert
Wer sich dafür interessiert, sollte einen Blick auf die Seite von “anonymous Prof” wagen, der einen ausführlichen - und wie die Überschrift verspricht- nett visualisierten Artikel verfasst hat”:
Tags:Daten, Grafik, Last.fm, visualisiertTo answer this question I used the VERY open properties of Last.fm and, with the help of their API, began collected data on relationships between users. I first crawled the main last.fm site and pulled out 364,499 user names. Then I wrote a php script that systematically pulled all the friend information for each user. Respecting the TOS and limiting myself to 1 query per second, I’m still collecting data (6 days, 17 hours, and 34 minutes in) with about 8 more days to go. As of now, I have data for 166,332 users (99,030 of whom have any friends). That results in 843,514 friends at an average of 8.52 friends / user.
