Call for Participation AAAI 2005 Spring Symposium on "Reasoning with Mental and External Diagrams: Computational Modeling and Spatial Assistance" Stanford University, California March 21-23, 2005 Symposium Description The role of diagrammatic representations in reasoning processes has been investigated from three different interdisciplinary perspectives: from computa­tional modeling, from spatial assist­ance, and with respect to the interplay of cognitive processes and external diagrams. All three fields have different foci of interest; however, the fields are closely related to each other. The primary goal of this symposium is to bring to­gether researchers to explore the role of dia­grams in sup­porting in­telligent reasoning processes in humans and technical systems, as well as in human-ma­chine interaction. Participants are asked to provide thoughts on the in­tegra­tion of the three perspectives rather than just presenting specific results from one of the fields. Sample questions of interest are: - how do mental representations and external diagrams influence each other while solving spatial problems? - how can computational cognitive models be used to better assess a user's cognitive needs in performing a spatial task? - how does knowledge about human imagery inform the process of de­signing and understanding external depictions? - what is the role of pictorial space as a representational medium for dealing with prob­lems on various scales? - How does inspection of diagrammatic representations assist mental model building by novices and by experts? - How are dynamic aspects of spatial information conveyed in diagrams and how are they processed in mental images? Besides examining the fundamental issues outlined above, we also aim to discuss practical scenarios and fields of application, such as in urban planning or architectural design, with re­spect to location-based services, or in instruction and education. The symposium will be scheduled to provide extensive discussion time and group inter­actions. There will be a series of presentations with significant question-and-answer time, as well as topic-oriented group discussion sessions.
