... Data-Oriented Semantic Analysis To use the DOP method not just for syntactic analysis, 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 a type logical formula ... unification variable is unified with the semantic formula on the substituting tree. (It is required that the semantic type of this formula matches the semantic type of the unification variable.)...
