Workshop on "Annotation Standards for Temporal Information in Natural Language" LREC 2002 27th May 2002, Las Palmas, Canary Islands - Spain Workshop scope and aims: ------------------------ The ability to identify and analyse temporal information is important for a variety of natural language applications, such as information extraction, question answering, and multi-document summarisation. Nevertheless, this area of research has been relatively unexplored. It became evident during an ACL 2001 workshop on temporal and spatial information processing that that some research institutions have started to work on different aspects of temporal information, but no consensus has been achieved yet on what and how temporal information should be identified in text. This workshop aims to provide a forum for researchers to present their work in this field and to discuss future developments such as building shared resources, e.g. temporally annotated corpora. It is timely to coordinate the effort being undertaken in the community at this stage of research into temporal information in text. Topics of interest include: --------------------------- The workshop organisers invite papers focussing on: - How are times referred to in text? - How are events temporally positioned? - How are events related to each other? - What is the relative role of tense/aspect vs. explicit time references? - What is the chronological structure of different types of text? (for example scientific reports vs. fiction vs. newswire texts) - resolution of deictic/partial/vague/relative time expressions - graphical representations of the temporal order of events - ontologies for temporal information, e.g. times and events - reasoning with/about temporal information - proposals for annotating temporal information and identifying appropriate corpora - evaluation of metrics for temporal annotation and evaluation of temporal annotation schemes - tools for annotation application areas include: - information extraction - question answering - planning - multi-document summarisation Authors whose work is directed at annotation schemes are encouraged to address (in their full paper) the example texts provided at http://www.dcs.shef.ac.uk/%7Ea ndrea/lrec2002/ - this is not obligatory. Workshop agenda: ---------------- The half-day workshop will consist of paper presentations, a panel session, and an open discussion session. We hope to arrange a follow-up meeting outside the workshop format to discuss future development and plans for possible collaborations. Organisers: ----------- Bill Black, UMIST, UK Rob Gaizauskas, University of Sheffield, UK Graham Katz, University of Osnabrueck, Germany Andrea Setzer, University of Sheffield, UK George Wilson, the MITRE Corporation, USA Program committee (provisional): -------------------------------- Bill Black, UMIST, UK Rob Gaizauskas, University of Sheffield, UK Graham Katz, University of Osnabrueck, Germany Inderjeet Mani, the MITRE Corporation, USA Allan Ramsay, UMIST, UK Andrea Setzer, University of Sheffield, UK Beth Sundheim, SPAWAR Systems Center, USA Janyce Wiebe, University of Pittsburgh, UK George Wilson, the MITRE Corporation, USA Important dates: ---------------- Deadline for submission of abstracts: 18/02/2002 Notification of acceptance: 11/03/2002 Camera-ready final copy for proceedings: 15/04/2002 Workshop: 27/05/2002 Submission: ----------- Abstracts for workshop contributions should not exceed two A4 pages (excluding references).
