SGER: Advances in Difficult Aspects of Reference Resolution

这个探索性的项目研究了指称消解领域中的两个困难现象：(1)复数代词的消解，它们可以与单个句法成分或篇章中不同位置的一组成分共指：它们、那两个、全部三个，等等；(2)第三人称单数和指示代词的消解，可以与单个句法成分共指，也可以与一段篇章共指：It，That，This，All，到目前为止，对这些现象的处理方式有限，因为最广泛采用的指代解析方法期望指代表达的先行词是前述上下文中的单个名词短语。在所研究的案例中，前置条件不需要以这种方式受到限制。这项工作的目的是实现类似人类的智能，以支持例如智能代理和人之间的复杂通信。它在理论上是有根据的，但将实际问题放在首位。组件算法可以在相对较短的时间内通知任何系统在任何领域的参考解析，推进已知类型的技术，而不依赖于任何意想不到的突破。要分发给社区的资源包括独立于系统的引用解析算法、相关实例及其语义表示的语料库、引用解析引擎，以及对成就、悬而未决的问题和进一步发展道路的关键调查。

SGER: Advances in Difficult Aspects of Reference ResolutionThis exploratory project is investigating two difficult phenomena in the domain of reference resolution: (1) the resolution of plural pronouns that can corefer either with a single syntactic constituent or with a set of constituents from different places in the text: they, those two, all three, etc. and (2) the resolution of 3rd person singular and demonstrative pronouns that can corefer either with a single syntactic constituent or with a span of text: it, that, this, all of this, etc. These phenomena have been treated in limited ways to date because the methods that have been most widely deployed for reference resolution have expected the antecedent for referring expressions to be a single noun phrase in the preceding context. In the cases under study, the antecedent need not be constrained in this way. This work is aimed at achieving human-like intelligence to support, for example, sophisticated communication between intelligent agents and people. It is theoretically grounded but keeps practical concerns at the fore. The component algorithms can inform reference resolution in any domain by any system in the relatively near term, advancing known types of technology and not relying on any unexpected breakthroughs. Among the resources to be distributed to the community are system-independent reference resolution algorithms, a corpus of relevant examples and their semantic representations, a reference resolution engine, and a critical survey of accomplishments, outstanding issues, and paths for further development.
