Title: Using the H-Index to estimate blog authority
Issue Date: 2011
Abstract: Link analysis is a technique frequently used in the rankingof web sites. On the web, we often encounter content thatis organized by entries, sorted from recent to old, and generallyfollows the structure of a blog. In this paper we exploreand evaluate the usage of a bibliometrics measure, called hindex,for the task of blog ranking, in an information retrievalcontext. We base our experiments on the TREC Blogs08collection, which comprises over 28 million posts. The resultsobtained indicate that the h-index is a robust metricthat allows for an improved relevance discrimination betweenblogs, when compared to the in-degree. Additionally, testsperformed using distinct versions of the post graph, indicatethat this metric might tolerate a certain level of link clutter.
