Báo cáo khoa học: "An Integrated Architecture for Generating Parenthetical Constructions"

The aim of this research is to provide a principled account of the generation of embedded constructions (called parentheticals) and to implement the results in a natural language generation system. Parenthetical constructions are frequently used in texts written in a good writing style and have an important role in text understanding. We propose a framework to model the rhetorical properties of parentheticals based on a corpus study and develop a unified natural language generation architecture which integrates syntax, semantics, rhetorical and document structure into a complex representation, which can be easily extended to handle parentheticals. . | An Integrated Architecture for Generating Parenthetical Constructions Eva Banik Department of Computing The Open University Walton Hall Milton Keynes e.banik@open.ac.uk Abstract The aim of this research is to provide a principled account of the generation of embedded constructions called parentheticals and to implement the results in a natural language generation system.

They are not part of the main predicate-argument structure of the sentence and are marked by special punctuation e.g. parentheses dashes commas in written texts or by special intonation in speech. Syntactically parentheticals can be realized by many different constructions e.g. appositive relative clauses 1a non-restrictive relative clauses 1b participial clauses 1c or subordinate clauses 1d . 1 a The new goal of the Voting Rights Act more minorities in political office - is laudable. wsj1137 b GE which vehemently denies the government s allegations denounced Mr. Greenfield s suit. wsj0617 c But most businesses in the Bay area including Silicon Valley weren t greatly affected. wsj1930 d So far instead of teaming up GE Capital staffers and Kidder investment bankers have bickered. wsj0604 A common characteristics of parentheticals is that they express information that is not central to the meaning of the overall message conveyed by a text or spoken utterance and since they are specifically marked by punctuation or intonation they allow the reader to
