Abstract：This paper demonstrates how to use the knowledge of logic and discourse structure to restrain the template-matching in information extraction (briefly , IE) , and to recover the missing information items or ones expressed by pronouns or deixis. It firstly explains what is the knowledge of the argument structure2based logic structure and discourse structure. Then it illustrates how the negative and aspect operators can change the type of event of a sentence and the matching relation between the sentence and the related event-template. And it shows how the embedding and nominalization of argument structure can change the syntactic position of some arguments and the related information items. Finally , it discusses how to use the knowledge of discourse structure to recover the missing information items or ones expressed by pronouns or deixis.
