SPEAR Ranking Algorithm
Michael and Albert have developed the SPEAR ranking algorithm for ranking users in social networks by their expertise and influence within the community.
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 as data source for our scientific experiments.
For developers and researchers alike, we provide a reference implementation of SPEAR as free and open source software.
