Modeling land-use changes using cellular automata: Challenges and perspectives

Abstract: In the first part of the presentation, conceptual aspects regarding land-use change modeling and cellular automata (CA) will be presented. Requirements for land-use change modeling will be identified and CA will be described as part of a new generation of models designed to study complex systems and gain insights about their spatial dynamics. Second, two major methodological issues associated to the implementation of a land-use CA model will be discussed namely the problem of scale and the challenge of model calibration. Research recently conducted by our team to address these issues will be presented, including a) the development of an object-based CA model that incorporates a flexible neighborhood definition, b) the implementation of an interactive method to dynamically create transition rules, and c) the application of a data mining technique to guide the selection of the driving factors and transition rules required for the model calibration. Finally, current limitations and research perspectives regarding land-use change modeling with CA will be highlighted.

 Processing Geographic Language.

Abstract: Information extraction systems have been developed to ground geographical references in text in terms of geo-coordinates, for use by geographical search engines and mapping tools. However, without a standard for how different types of geographical entities should be tagged, such systems are impossible to reliably evaluate. I will describe an annotation scheme called SpatialML, that has been used to automatically tag places, their geo-coordinates, and spatial relationships in a variety of text corpora. SpatialML represents spatial relationships among geographical regions in terms of the Region Connection Calculus, and it has also been mapped to the Generalized Upper Model ontology, is part of the emerging ISO-Space standard activity, and is currently being integrated with the TimeML time markup standard.

Spatial, Temporal and Social: Learning From and About Humans with 
Social Media

Abstract: Social media -- online services that encourage content sharing through  individual participation -- have encouraged and enabled people to share various types of information in social and public settings. Many of the social media services allow their users to annotate any piece of content with location (and time) metadata. Taken in aggregate, this content can get a spatio-temporal representation of the world's interests, and even attitudes and intentions.  In my talk, I will show how these spatio-tempo-social media resources can, for example, allow extraction of place and event semantics and other information that is not easily attainable otherwise; and help us understand and explore the world. Beyond learning about the world, this type of spatio-tempo-social data may also provide opportunities to learn about humans -- and humanity.
