New Metrics for Newsblog Credibility

Abstract

The blogosphere is an invaluable source of insight into attitudes towards significant world and local events. Traditional measures of topical relevance, timeliness, specificity and credibility are inadequate when it comes to blogs, however, due to their short length, high degree of quotation, exophoricity, and the short life cycle of blog postings. In this paper, we motivate a novel metric for blog credibility that is one of the metrics underlying a blog search and analytics engine we are constructing.
