Token-Based Minimal Recursion Semantics

By Mats Dahllöf


ctic embedding is eliminated. The elementary units of the representations are called elementary predications (EPs). The EPs roughly correspond to the basic semantic units of ordinary logic. The MRS representations are sets or lists of EPs. Each EP is associated with a so-called handle, an identifying label. Some EPs, for instance, quantifiers, carry features which take handle values. This allows feature-handle connections to indicate operator scope. So, syntactic embedding is not needed for that purpose, as in ordinary predicate calculus. The "ordinary" predicate EPs carry a handle value, as all EPs do. Another feature identifies the predicate, i.e. the lexeme. Additional features correspond to the logical arguments of the predicate. Their number and their kinds depend on which predicate we're dealing with. Apart from handle and lexeme features, generalized quantifiers involve a bound variable, a restriction and a body. The 1 restriction and the body are scopal features, taking hand
