Call for Participation

Workshop on Spatial and Temporal Reasoning

Pasadena, California, USA

Sunday, 12 July 2009

New Submission Deadline: 3 April 2009


This workshop is intended as a forum for discussion, exchange of points of view, assessment of results and methods, and as a source of dissemination and promotion of the newest advances in the area of spatial and temporal reasoning. Recent years have witnessed remarkable advances in some of the longstanding problems of the field (for instance, new results about tractability for spatial calculi, explicit construction of models, characterization of important subclasses of relations), as well as in the development of new areas (the appearance of new integrated spatio-temporal calculi is one example, as well as the development of multi-dimensional spatial calculi). Likewise, proposals have been made to remedy some of the weak points of the symbolic approach, by introducing fuzzy versions of classical calculi, or importing non-monotonic techniques for dealing with incomplete information. Furthermore, reasoning about space also typically involves reasoning about changing spatial configurations, and in more realistic scenarios, integrated reasoning about space, actions and change. Recent work supporting this paradigm has also explicitly addressed the interactions between the spatial reasoning domain and the field of reasoning about actions and change. At the same time, leaders in AI have sounded the need for solving real problems and making the work on representation and reasoning relevant to the real world.

Paper Presentations and Demos

The format of the workshop has been designed in accordance with the general goal of offering a structure for exchange. The program will include a number of presentations by the invitees representing several different aspects of spatial and temporal reasoning, followed by discussions.

In addition to the regular paper presentations, the workshop also includes a functional session where prototypical and complete systems will be demonstrated. It is expected that the proposed systems, or parts thereof, in this category will involve spatial and/or temporal reasoning in some form. Of special interest to the aims of the demo session are systems where the application of formal qualitative spatial calculi is highlighted. In addition to the thematic requirements, selections will be made on the basis of how closely the illustrated techniques utilize existing formalizations developed in the area of qualitative spatial representation and reasoning.


The workshop is open to all members of the AI community. Up to 75 participants will be selected to attend the workshop, contributing and participating in discussions. Accepted papers will be included in the workshop working notes to be distributed at IJCAI. Screening will be based on reviews and relevance to the workshop goals.

Submission Requirements

Electronic submissions are solicited in PostScript or PDF format. The papers, starting with title, authors' names, affiliations, postal and email addresses, followed by keywords, and concluding with relevant bibliographic references, should fit on 4 to 10 single-spaced typewritten A4 or 8.5 x 11 inch pages, in the form of an extended abstract or complete research, survey, or position paper.

Interested authors should submit their paper in PDF or PostScript format by email to Hans Guesgen. It is highly recommended to use the AAAI style for formatting the paper. Papers should not exceed 10 pages and should be in the form of an extended abstract or complete research, survey, or position paper. Selection of participants will be based on relevance to the indicated focus of the workshop, clarity of the work submitted, and the strength of the research.

Authors of selected workshop papers will be invited to submit extended versions of their papers after the workshop, taking into account any feedback that they received during the workshop. These papers will be peer-reviewed and considered for publication in a special issue of the Journal of Universal Computer Science.
