Modelling with stakeholders - Next generation
Alexey Voinov,Nagesh Kolagani,Michael K. McCall,Pierre D. Glynn,Marit E. Kragt,Frank O. Ostermann,Suzanne A. Pierce,Palaniappan Ramu +7 more
TL;DR: Modelling with Stakeholders is updated and builds on Voinov and Bousquet, 2010, and structured mechanisms to examine and account for human biases and beliefs in participatory modelling are suggested.

Automatic identification of eyewitness messages on twitter during disasters
TL;DR: This work investigates different types of sources on tweets related to eyewitnesses and classifies them into three types, observing that words related to perceptual senses tend to be present in direct eyewitness messages, whereas emotions, thoughts, and prayers are more common in indirect witnesses.
Journal ArticleDOI
Digital Earth from vision to practice: making sense of citizen-generated content
TL;DR: The results of a two-year research project exploring the extent to which it is possible to extract information useful for policy and science from the large volumes of messages and photos being posted daily through social networks indicate that six of eight major fires in France in the summer of 2011 were detected accurately.

A conceptual workflow for automatically assessing the quality of volunteered geographic information for crisis management
TL;DR: This paper aims to present a complete conceptual work flow for the assessment of user generated geographic content, or volunteered geographic information (VGI), for the use in a crisis management context.
Journal ArticleDOI
Citizen-based sensing of crisis events: sensor web enablement for volunteered geographic information
Sven Schade,Laura Díaz,Frank O. Ostermann,Laura Spinsanti,Gianluca Luraschi,Simon Cox,Manoli Nuñez,Bertrand De Longueville +7 more
TL;DR: This paper extends previous efforts describing a workflow for VGI integration into SDI and further advance an initial set of VGI Sensing and event detection techniques, serving central building blocks for a Digital Earth's nervous system, which is required to develop the next generation of (geospatial) information infrastructures.
