On the interaction of syntax and semantics in a syntactically guided caseframe parser
Harald Trost, Ernst Buchberger, Wolfgang Heinz · 1988
In this paper we describe a parser for German based on semantic caseframe instantiation guided by a syntactic analyzer. Pure caseframe parsers lack the ability to capture syntactic regularities, which leads to redundancy in the lexicon and/or poor syntactic coverage. By combining caseframe matching with an explicit syntactic analysis our parser overcomes this problem.Approaches well suited for English are not easily transported to German with its rich morphology and its free constituent order at the clause level. Our parser which incorporates two different interacting parsing strategies is well adapted to the needs posed by German grammar.
