CALL FOR PAPERS
WORKSHOP ON TEMPORAL AND SPATIAL INFORMATION PROCESSING
ACL'2001 Conference
Toulouse, France
July 7, 2001
Temporal and spatial information is ubiquitous in natural language, yet
many challenging computational issues are relatively unexplored. This
workshop will bring together researchers working on a variety of tasks
that depend on representing spatial and temporal information in natural
language.
We invite papers on any topic dealing with automatic processing of
spatial or temporal information in natural language. As a special theme
of this workshop, we would also like to encourage the discussion of
common issues across spatial and temporal domains. For example, systems
that process temporal or spatial information need to deal with
'absolute' references ("November 18, 1999", "Toulouse"), as well as
relative references ("now", "here", two weeks ago", "thirty miles north
of Paris"), and vague references ("some time in June", "a town in
Provence", "nearly a year ago", "near Dusseldorf", "Tuesday morning",
"southern England"). There are also many parallels between the way
events are characterized in time and objects are characterized in space.
For example, events can be described relative to some point or interval
in time (e.g., "I met John yesterday", "he was crossing the street.")
while objects in space can be described in relation to some place,
object, or in terms of movement (e.g, "the cup was on top of that", "it
fell off").
The topics covered will include corpus-based, knowledge-based, and
hybrid approaches to: =
=B7 resolution of temporal and spatial references, especially
discourse-dependent ones =
=B7 standards for encoding the values of temporal and spatial expressions=
in natural language
=B7 temporal and spatial characterization of events
=B7 establishing coreference, ordering and inclusion relations in spatial=
or temporal information
=B7 computational analysis of tense and aspect
=B7 semantics of indeterminate or vague temporal and spatial references =
=B7 semantics and pragmatics of spatial and temporal prepositions
=B7 leveraging of ontologies for spatial and temporal information
=B7 reasoning about modals, i.e., possible events, necessary events,
counterfactual events, etc. =
=B7 application of logics for spatial and temporal reasoning
=B7 analysis of temporal and spatial aspects of narrative structure
=B7 generation of temporal and spatial references
=B7 linguistic and graphical representations
Application areas include:
=B7 machine translation (e.g., translating temporal and spatial
references)
=B7 question answering (e.g, answering "when" or "where" questions)
=B7 information extraction (e.g., normalizing time values for entry into
databases, disambiguating place names using a gazetteer)
=B7 summarization (e.g., producing temporally coherent summaries of
multiple documents, or generating route plans)
=B7 information retrieval (e.g., indexing broadcast news by event time)
=B7 information visualization (e.g., constructing event chronologies,
geospatial visualization)
=B7 multimodal interfaces (e.g., interfaces to simulations, gesture and
speech input graphical applications, navigation systems)
=B7 interfaces to spatial and temporal databases (e.g., normalizing
temporal and spatial references)
=B7 planning and problem solving
=B7 multimedia presentations (e.g., generating textual descriptions or
captions, scene and route descriptions, generation of spatio-temporal
maps)

Workshop FROM SENTENCE PROCESSING TO DISCOURSE INTERPRETATION: CROSSING THE BORDERS Utrecht University, Utrecht institute of Linguistics OTS Utrecht (The Netherlands), 2-3 July 2001 CALL FOR PAPERS The aim of this workshop is to foster the interaction of two areas in psycholinguistics that have traditionally been pursued quite independently of one another: sentence and discourse processing. Discourse processing research has dealt primarily with issues like relational and y"eferential coherence - i.e. conceptual issues, whereas sentence processing has traditionally focused on the analysis of sentence structure. Recently, however, signs are noticed of a movement towards convergence. In y"entence processing, issues pertaining to interpretation are gradually assuming � more prominent position on the research agenda. In the field of �iscourse processing, the conviction is gaining strength that detailed analyses y"f linguistic factors, including grammatical properties of sentences as "processing instructors", are necessary for the development of adequate models. It would seem then, that the traditional border between the discourse level and the sentence level is being crossed increasingly y"ften from both sides. Researchers from the two traditions are beginning to recognize each other's contribu-tions to the field at large, as well as their interdependence. The workshop aims at and intends to stimulate and inspire researchers from both fields to share and discuss their ideas and empirical results. Particularly, the focus will be on issues that are at the interface of sentence and discourse processing. A few examples of the kinds of topics that would fit in the workshop are: � Are processing operations at the level of discourse and sentence processing principally different, or does the same computation system subserve the two domains? � Is Logical Form (the interface between syntax and the conceptual system in the generative framework) a psycholinguistically viable concept? � Does discourse context always interfere with sentence parsing, or are there examples of genuinely autonomous sentence-level processes? � How can linguistic characteristics of discourse (grammatical structure, connectives, anaphora) be further specified as processing instructions for discourse processing? Invited Speakers Jos van Berkum, University of Amsterdam Lyn Frazier, University of Massachusetts, Amherst Alan Garnham, University of Sussex Ted Gibson, MIT Leo Noordman, Tilburg University Tony Sanford, University of Glasgow Wietske Vonk, Max Planck Institute for Psycholinguistics Submission of Papers The programme of the workshop comprises 10 - 20 slots for oral (25 minutes, including discussion time) and poster presentations, which will be y"elected on the basis of abstracts submit-ted to the organizing committee. Your abstract should clearly summarize the aim of your study, its theoretical motivation and the principal results. Abstracts should not exceed one page (A4 or Letter) in length. Set linespacing to 1.5 (minimally), and use a 12-point font. Add your name, address, affiliation, e-mail address, and telephone number on a separate page. Send a soft �opy of your abstract by electronic mail to: mailto:processingMail to author|Respond to list|Read more issues|LINGUIST home page|Top of issuelet.uu.nl, and y"tate "submission workshop" in the subject header.
