Anchoring Temporal Expressions in Scheduling-related Emails
نویسندگان
چکیده
In this paper we adopt a constraint-based representation of time, Time Calculus (TC), for anchoring temporal expressions in a novel genre, emails. Email is sufficiently different from most studied genres newswire texts, and its highly under-specified nature fits well with our representation. The evaluation of our anchoring system shows that it performs significantly better than the baseline, and the result compares favorably with some of the closest related work.

Understanding Temporal Expressions in Emails
Recent years have seen increasing research on extracting and using temporal information in natural language applications. However most of the works found in the literature have focused on identifying and understanding temporal expressions in newswire texts. In this paper we report our work on anchoring temporal expressions in a novel genre, emails. The highly under-specified nature of these exp...
متن کاملSemEval-2010 Task 13: Evaluating Events, Time Expressions, and Temporal Relations (TempEval-2)
We describe the TempEval-2 task which is currently in preparation for the SemEval-2010 evaluation exercise. This task involves identifying the temporal relations between events and temporal expressions in text. Six distinct subtasks are defined, ranging from identifying temporal and event expressions, to anchoring events to temporal expressions, and ordering events relative to each other.
متن کاملEvent-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces
Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...
متن کاملHandling Temporal Relations in Scheduling Dialogues for an MT System
Handling temporal information has been a main concern of areas such as natural language processing planning and knowledge repre sentation In scheduling dialogues temporal reference is central and the relations between temporal expressions contain much of the ellip sis and anaphora to be resolved As a consequence lling in missing information contributes to the understanding of the text In this p...
متن کاملBCCWJ-TimeBank: Temporal and Event Information Annotation on Japanese Text
Temporal information extraction can be divided into the following tasks: temporal expression extraction, time normalisation, and temporal ordering relation resolution. The first task is a subtask of a named entity and numeral expression extraction. The second task is often performed by rewriting systems. The third task consists of event anchoring. This paper proposes a Japanese temporal orderin...
