SPEAR Ranking Algorithm

Ching-man Au Yeung and I have developed the SPEAR ranking algorithm for ranking users in social networks by their expertise and influence within the community.

SPEAR Algorithm: Discoverers and Followers

Our work on SPEAR has been covered by international press and news media, including Technology Review and Communications of the ACM as well as the world’s top technology blogs such as ReadWriteWeb. We have been also very happy that Yahoo! invited us to write a featured article about SPEAR, considering that we used its social bookmarking service Delicious.com (which was owned by Yahoo back then) as data source for our scientific experiments.

For starters, you want to read my quick introduction on how to use the SPEAR Python library.
