... COMPUTING SEMANTIC GRAPHS FROM SYNTACTIC GRAPHS 49 An important test of the utility of syntactic graphs is to demonstrate that they can be used di- rectly to compute corresponding semantic graphs ... conclusion, we have presented a computa- tional method for directly computing semantic graphs from syntactic graphs.
