Therefore, we incorporate argument type checking in our EM process to ensure that it maps verbs to relations whose argument types match: • In the E-Step, we make sure that unlabeled instances are only labeled with relations that have the same argument types as the instance and that share some verbs with the instance.
in the E-step we compute P (y i (e m ,e n ) = 1 • In the M-step, we make sure that verbs are only mapped to relations whose argument types match at least one of the instances that co-occur with the verbs in SV O .
