TAILIEUCHUNG - Báo cáo khoa học: "SUBJECTERASING AND PRONOMINALIZATION IN ATALIAN TEXT GENERATION"

Certain Romance languages such as Italian, Spanish and Portuguese allow the subject to be erased in tensed clauses. This paper studies subject erasing in the framework of a text generation system for Italian. We will prove that it is first necessary to try to pronominalize the subject. Therefore, we are led to study the synthesis of subject and complement personal pronouns. In Romance languages, personal pronouns raise many syntactic problems, whose solution is complex in a generation system. We will see that pronominalization plays a fundamental role in the order in which the elements of a clause are synthesized,. | SUBJECT ERASING AND PRONOMINALIZ ATION IN ITALIAN TEXT GENERATION Fiammetta Namer LADL Universitó Paris VII 2 place Jussieu 75251 Paris Cedex 05 France ABSTRACT Certain Romance languages such as Italian Spanish and Portuguese allow the subject to be erased in tensed clauses. This paper studies subject erasing in the framework of a text generation system for Italian. We will prove that it is first necessary to ưy to pronominalize the subject. Therefore we are led to study the synthesis of subject and complement personal pronouns. In Romance languages personal pronouns raise many syntactic problems whose solution is complex in a generation system. We will see that pronominalization plays a fundamental role in the order in which the elements of a clause are synthesized and consequently in the synthesis of this clause. Moreover the synthesis of a clause must take into account the fact that subject erasing and the synthesis of complements are phenomena which depend on each other. The complex algorithm that must be used for the synthesis of a clause will be illusưed in various examples. 1 Presentation of the generation system In a generation system two questions must be answered What to say in order to decide on the content of the message to be produced and How to say it producing the text which carries this content . We are interested only in the How to say it question. We have adapted for Italian the generation system developped by 1987a 1987b which produces texts in French and English. This generator includes two components the strategic component and the syntactic component. 1 The strategic component takes both conceptual and linguistic decisions. It selects a discourse structure which determines the order of information the number and form of the sentences of the text to be generated. It returns a text template which is a list of the form Sentl Punctl . Senti Puncti . Sen tn Punctn where Puncti is a punctuation mark and Send a sentence template. For the .
