2012 i2b2 Temporal Relations Dataset

The Sixth Informatics for Integrating Biology and the Bedside (i2b2) Natural Language Processing Challenge for Clinical Records focused on the temporal relations in clinical narratives. The organizers provided the research community with a corpus of discharge summaries annotated with temporal information, to be used for the development and evaluation of temporal reasoning systems. 18 teams from around the world participated in the challenge. During the workshop, participating teams presented comprehensive reviews and analysis of their systems, and outlined future research directions suggested by the challenge contributions.

第六次融合生物与临床床边（i2b2）信息学挑战赛专注于临床叙事中的时间关系。组织者向研究界提供了一个标注有时间信息的出院总结语料库，以供开发与评估时间推理系统之用。来自世界各地的18支队伍参与了此次挑战。在研讨会期间，参赛队伍对其系统进行了全面综述与分析，并概述了由挑战赛贡献所提出的未来研究方向。
