摘要： A system is disclosed for reconciling opinions generated by agents with respect to one or more predicates. The disclosed system may use observed variables and a probabilistic model including latent parameters to estimate a truth score associated with each of the predicates. The truth score, as well as one or more of the latent parameters of the probabilistic model, may be estimated based on the observed variables. The truth score generated by the disclosed system may enable publishers to reliably represent the truth of a predicate to interested users.

摘要： Techniques for testing rule-based query transformation and generation are described. An apparatus may comprise: a context component operative to receive a search query and determine a query execution context; a rules component operative to receive the determined query execution context and the search query and to determine a set of fired rules; a transformation component operative to receive the set of fired rules, the search query, and the query execution context and determine one or more transformed queries; and a results component operative to determine a search query analysis based on the one or more transformed queries, wherein the search query analysis does not depend on performing a search using the search query. Other embodiments are described and claimed.
