N2 - Search engines have become an important decision making tool today. Decision making queries are often subjective, such as "best sedan for family use," "best action movies in 2010," to name a few. Unfortunately, such queries cannot be answered properly by conventional search systems. In order to address this problem, we introduce Consento, a consensus search engine designed to answer subjective queries. Consento performs subdocument-level indexing to more precisely capture semantics from user opinions. We also introduce a new ranking method, or ConsensusRank that counts in online comments referring to an entity as a weighted vote to the entity. We validated the framework with an empirical study using the data on movie reviews. Copyright is held by the author/owner(s).
