Identifying Objects, Processes and Events (IOPE) PDF Print E-mail

Organizers: Antony Galton, Mike Worboys, Matt Duckham, Jake Emerson

With the development of new sensor and communication technologies, there is an ever more pressing need for reliable and properly codified methods for deriving high-level information from masses of dynamic spatio-temporally distributed data. Data sources of relevance here include wireless sensor networks, CCTV, GPS, crowd-sourcing, and many others. The data may in some cases be understood as sample points from a continuous dynamic field, in other cases they may represent discrete objects forming crowds, swarms, or other collective entities. The desired high-level information can include the identification of objects or object-like aggregations, and the processes and events that they participate in, e.g., motion, expansion, contraction, splitting, or merging. Although much work is now being done on investigating such phenomena, there is still a need for a unified theoretical framework and common vocabulary to support the development of tools and techniques for handling them. This workshop is intended to provide a forum for researchers who are working in this area, with particular reference to representation techniques, algorithms, and applications.

Ontology of Spatial Thinking and Reasoning: Multi-Disciplinary Reconciliation PDF Print E-mail

Organizers: K. Grossner, D. Montello and D. Janelle (University of California, Santa Barbara)

This workshop will discuss the ontology of spatial thinking and reasoning, that is, what concepts do people with different backgrounds, disciplines, training, etc., use to think and reason about spatial aspects of problems. This topic has been discussed by at least three research communities during the past two decades: those conducting basic research in behavioral and cognitive science, those developing and evaluating software and information systems, and those designing and evaluating education programs in physical science, geography, or other fields. Our hope is to bring representatives from these three communities together in an effort to make progress on both domain-specific and shared goals. Among the questions we plan to address: Are there spatial concepts, principles, and reasoning tasks that are general across all fields, and if so, what are useful or appropriate ways to organize them? More broadly, is a unified ontology of spatial thinking and reasoning a feasible and worthwhile goal, and if so, for what purposes?

Cognitive Engineering for Mobile GIS PDF Print E-mail

Organizers: Krzysztof Janowicz, The Pennsylvania State University, USA; Martin Raubal, ETH Zurich, Switzerland; Antonio Krüger, Saarland University, Germany; Carsten Keßler, University of Muenster, Germany

While mobile computing and Location-Based Services have been around for more than a decade, it is just now that the availability of open source APIs and GPS-enabled smartphones make them accessible to a broader public. Citizens as sensors, location-based social networks, and lifelogs offer highly heterogeneous and timely sources of data that require processing and integration to develop mobile recommender and decision support systems. Mobile services are highly affected by contextual information, they have reduced user interfaces, and require additional inference to extract user profiles and tasks from implicit information such as time and location. The combination of these factors makes cognitive engineering methods a promising approach. Such methods integrate cognitive and computer science approaches to the design and construction of machines. More specifically, when applying cognitive engineering to Mobile GIS, principles of human spatial cognition regarding the representation and processing of spatial and temporal aspects of phenomena, and aspects of mobile decision-making must be considered.

An Interdisciplinary Approach to Understanding and Processing Sketch Maps PDF Print E-mail

Organizers: Jia Wang, Klaus Broelemann , Malumbo Chipofya, Angela Schwering (University of Münster, Germany), Jan Oliver Wallgrün (University of Bremen, Germany)

Sketch maps have been studied for decades by various disciplines such as Cognitive Psychology, Geographical Information Science, Artificial Intelligence, Computer Vision and Human Computer Interaction. Compared with traditional maps from authorized mapping agencies, sketch maps are easy to produce by ordinary citizens, firmly related to human spatial thinking, and well represent human environmental knowledge. In a world where spatial information is available for everyone, there is still a gap between qualitative human perception and quantitative digital representations of spatial information. Processing of sketch maps can be a way to fill this gap and thereby advance spatial information systems towards a more natural human-computer interaction. Although researchers have been investigating sketch maps for over 50 years, there exist many unsolved problems that require contributions from several disciplines to come up with comprehensive solutions. This workshop will bring together researchers from multiple disciplines and foster mutual understanding and cooperation between them.
