... Data-Oriented Semantic Analysis To use the DOP method not just for syntactic anal- ysis, but also for semantic interpretation, four steps must be taken: 1. decide on a formalism for representing ... the semantic formulas of its daughter nodes. Using this convention, the semantic annotation of the corpus trees is indicated as follows: • For every meaningful lexical node...

... to calculate a global score for a representation seems a rather arbitrary procedure. Such a uniform metric, even if it can model actual linguistic knowledge, forces the grammar writer to ... no formal or linguis- tic guarantee that this will be the case for the relation as a whole or for the translation steps between inter- mediate levels of representation. (An attempt to for...
