In Adwait Ratnaparkhi's 1998 Ph.D. dissertation, "maximum entropy models for natural language ambiguity resolution", he discusses the use of contextual predicates to aid in (machine) learning. Each probabilistic sample from the solution space is presented as a function (i.e. a contextual predicate) and its informational useful is weighted by a set of Yes or No questions, as to whether the solution's "context" also exists in the solution space.
This allows users to enter highly detailed queries without the risk that important solution sets that do not exactly match the query will not be found.
