• Abstract: Temporal relation classification is the task of determining the temporal relation between pairs of temporal entities in a text. Despite recent advancements in natural language processing, temporal relation classification remains a considerable challenge. Early attempts framed this task using a comprehensive set of temporal relations between events and temporal expressions. However, due to the task complexity, datasets have been progressively simplified, leading recent approaches to focus on the relations between event pairs and to use only a subset of relations. In this work, we revisit the broader goal of classifying interval relations between temporal entities by considering the full set of relations that can hold between two time intervals. The proposed approach, Interval from Point, involves first classifying the point relations between the endpoints of the temporal entities and then decoding these point relations into an interval relation. Evaluation on the TempEval-3 dataset shows that this approach can yield effective results, achieving a temporal awareness score of $70.1$ percent, a new state-of-the-art on this benchmark.

• Only One Relation Possible? Modeling the Ambiguity in Event Temporal Relation Extraction [30.319025749352246]
  Event Temporal Relation Extraction (ETRE) aims to identify the temporal relationship between two events. We propose a multi-label classification solution for ETRE (METRE) to infer the possibility of each temporal relation independently. Our method can effectively utilize the textitVague instances to improve the recognition for specific temporal relations.

  This paper presents a new annotation scheme that clearly defines the criteria based on which temporal relations should be annotated.

The result is a new dataset, the TIMELINE corpus, in which improved inter-annotator agreement was obtained.

It is capable of identifying the majority of discourse relations with existing explicit discourse connectives, but the implicit discourse relation remains a formidable challenge.
