... 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 ... Sometimes, syntactic ambiguities are re- solved during semantic processing, but often re- main even through coherence analysis at the dis- course level. Finally, after...

The improvement suggests that the proposed framework with syntactic structural features is more effective in modeling the bilingual syntactic ... the structural features, rendering the syntactic rich task of sub-tree align- ment less convincing and attractive. This may be due to the fact that the syntactic structures in...
