Minimal Recursion Semantics (MRS) is a computational semantic framework which has been widely adopted in the last several years. In this talk we will present a detailed introduction to the principles of this framework, the motivations of this approach, the basic definitions of MRS, and the techniques which MRS uses to build a semantic representation from a syntactic tree (semantic composition).
Having introduced MRS, we will show how this framework compares to the Logical Form (LF) representation produced by the TRIPS parser. We use several examples to demonstrate that these two formalisms are very similar in their descriptive power. We propose a simple algorithm to convert LF representation of a sentence to its MRS representation.
