指代是自然语言中常见的语言现象,大量出现在篇章或对话中。随着篇章处理相关应用日益广泛,指代消解也显示出前所未有的重要性,并成为自然语言处理上热门的研究问题。针对指代和指代消解的有关问题,本文对基本概念作了说明,分析了语言中典型的指代现象和指代消解所需的基本语言知识;同时,介绍了指代消解中有代表性的几种计算模型和近10年来采用的若干实现技术。
Abstract
Anaphora occurs throughout discourse or dialogue. Their high frequencies make anaphora resolution one key problem in discourse processing which attract attention of increasing researchers. In this article ,some issues of anaphora resolution will be discussed , such as basic concepts , special referring phenomena ,necessary knowledge on anaphora resolution. Some typical computational models of anaphora resolution and implement technologies will be given as well.
