AGORA-IQA: Information Quality Assurance

Research Project: An approach for quality assessment and communication of volunteered geographic information in citizen observatories for the purpose of flood management

Abstract: Volunteered Geographic Information (VGI) has emerged as a potential source of geographic information for different domains. Despite the many advantages associated with it, such information lacks of quality assurance, since it is provided by individuals with different motivations and backgrounds. In response to this, several methods have been proposed to assess the quality of volunteered geographic information of different platforms. However, there has been little investigation aimed at explaining how cross-platform data could be used for quality assessment in the context of flood management. Moreover, it is not clear how the volunteer could be inserted in the quality assessment process in order to improve the overall quality. In this work, we propose an approach to assess the quality of volunteered geographic information in flood management domain that combines cross-platform data, i.e. OpenStreetMap and social media data, and authoritative data.
