Technology Review Article on Our Expertise Ranking Approach From SIGIR '09

The US magazine Technology Review has published an article about our SPEAR algorithm for expertise ranking in the Social Web. My co-worker Ching-man Au Yeung from University of Southampton and I just returned from this year’s ACM SIGIR conference where we presented this joint work. The TR article A Better Way to Rank Expertise Online summarizes our approach quite well, and we’re really happy about the very positive feedback therein from researchers like Professor Jon Kleinberg (the inventor of the HITS algorithm on which our SPEAR algorithm is based), Scott Golder (his publication together with Huberman on usage patterns in collaborative tagging systems is one of the earliest and currently most cited works in the area of the Social Web) and Ciro Cattuto (very nice work on social dynamics and network characteristics of folksonomies). Thanks!
