What do you know? A topic-model approach to authority identification
Summary
In this paper the authors present a preliminary study of basic approaches to the problem of identifying authoritative documents in a given domain using textual content and report their best performing approach using Hierarchical Topic Models [Blei et al, 2004]. Authoritative documents are ones which exhibit novel and relevant information relative to a document collection while demonstrating domain knowledge. Authors define authoritativeness identification task as a ranking problem and focus on product (book GoodReads and restaurantYelp) reviews utilizing user votes as proxy for helpfulness and authoritativeness.
