11. The method of claim 7 , wherein when considering the argument structure consistency between the SRL results on the source side and the target side, the objective is to maximize a number of correctly aligned arguments, and plurality of constraints comprise: 1) Conformity with bilingual SRL result: For all candidates on both source and target sides, only those that are chosen to be arguments on each side are aligned; 2) One-to-many alignment limit: An argument cannot align with more than three arguments; and 3) Complete argument alignment: Each argument on the source side is aligned with at least one argument on the target side, and vice versa, wherein a penalty is induced when this constraint is violated.
7. The method of claim 1 , wherein the performance of the joint inference in step 4 produces an SRL result on a source side and an SRL result on a target side and the joint interference is based on: a correctness of the SRL result on the source side, a correctness of the SRL result on the target side, and an argument structure consistency between the SRL results on the source side and the target side.
