Reverse Queries in DATR
  DATR is a declarative representation language for lexical information and as such, in principle, neutral with respect to particular processing strategies. Previous DATR compiler/interpreter systems support only one access strategy that closely resembles the set of inference rules of the procedural semantics of DATR (Evans & Gazdar 1989a). In this paper we present an alternative access strategy (reverse query strategy) for a non-trivial subset of DATR.
