Leveraging information from relevance assessments has been proposed as an effective means for improving retrieval. We introduce a novel language modeling method which uses inform...

We argue that when objects are characterized by many attributes, clustering them on the basis of a random subset of these attributes can capture information on the unobserved attr...
Ordinary logical implication is not enough for answering queries in a logic database, since especially negative information is only implicitly represented in the database state. M...
