Stay Together：一个单先行回指和分裂先行回指解析系统
Stay Together: A System for Single and Split-antecedent Anaphora Resolution
摘要：
近年来，对基本的、单先行词回指的研究有了很大的进展。因此，研究人员开始更加关注更复杂的回指情况，如分裂先行回指，如时代华纳正在考虑对电信公司购买Showtime网络公司一半股份的计划提出法律挑战，此举可能导致两家强大公司之间的全面战争。分裂先行回指比单先行回指更罕见，也更复杂;因此，它在许多旨在测试共指的数据集中没有注释，并且以前解决这种类型回指的工作是在不切实际的条件下进行的，假设黄金提及和/或黄金分裂先行回指是可用的。这些系统也只关注分裂先行回指语。在这项工作中，我们介绍了一个系统，解决了单一和分裂先行回指，并评估它在一个更现实的设置，使用预测提到。我们还开始解决如何使用标准的共指评估指标来评估单个和分裂先行回指的问题。
英文摘要：
The state-of-the-art on basic, single-antecedent anaphora has greatly improved in recent years. Researchers have therefore started to pay more attention to more complex cases of anaphora such as split-antecedent anaphora, as in Time-Warner is considering a legal challenge to Telecommunications Inc's plan to buy half of Showtime Networks Inc-a move that could lead to all-out war between the two powerful companies. Split-antecedent anaphora is rarer and more complex to resolve than single-antecedent anaphora; as a result, it is not annotated in many datasets designed to test coreference, and previous work on resolving this type of anaphora was carried out in unrealistic conditions that assume gold mentions and/or gold split-antecedent anaphors are available. These systems also focus on split-antecedent anaphors only. In this work, we introduce a system that resolves both single and split-antecedent anaphors, and evaluate it in a more realistic setting that uses predicted mentions. We also start addressing the question of how to evaluate single and split-antecedent anaphors together using standard coreference evaluation metrics.
