摘要:

时间深深地融入了人们对世界的感知和交流。我们几乎是无意识地为我们的语言话语提供了时间线索,比如动词时态,没有这些线索,我们很难造句。从文本中提取时间线索,并构建关于描述事件顺序的全局时间视图是自动自然语言理解的主要挑战。时间推理是将不同的时间线索组合成一个连贯的时间视图的过程,在时间信息抽取中起着核心作用。本文综述了过去几十年来关于文本时间信息抽取的时间推理研究,并提供了一个将符号推理与基于机器学习的信息抽取系统相结合的案例研究。

英文摘要:

Time is deeply woven into how people perceive, and communicate about the world. Almost unconsciously, we provide our language utterances with temporal cues, like verb tenses, and we can hardly produce sentences without such cues. Extracting temporal cues from text, and constructing a global temporal view about the order of described events is a major challenge of automatic natural language understanding. Temporal reasoning, the process of combining different temporal cues into a coherent temporal view, plays a central role in temporal information extraction. This article presents a comprehensive survey of the research from the past decades on temporal reasoning for automatic temporal information extraction from text, providing a case study on the integration of symbolic reasoning with machine learning-based information extraction systems.
