LINKing and analyzing Volunteered Geographic Information (VGI) across different platforms
Pre Conference Workshop at 19th AGILE International Conference on Geographic Information Science 2016. Helsinki, June 14th 2016
Deadline for Call for Short Paper (AGILE short paper format): April 25th 2016
The number of Volunteered Geographic Information (VGI) and social media platforms is continuously growing, providing massive datasets of georeferenced content that is either actively contributed (e.g. adding data to OSM, Mapillary, or Flickr) or collected through more passive modes (e.g. enabling geolocation in Twitter feeds). Whereas contribution behavior for individual crowdsourcing applications has already been extensively analyzed in the literature, it is less understood if and how users participate in several crowd sourcing activities. Hence several research questions relevant to a better understanding of community involvement in data contributions have evolved. These include for example, whether activity spaces in different sources are spatially co-located or spatially distinct for individual contributors, or whether contributor communities evolve across platforms. As an example, users started to cross-link data from different platforms, e.g. by mapping OSM point of interests (POIs) and street features (e.g. street lamps, sidewalk information) based on Mapillary photographs, or by tagging Flickr pictures with OSM tags.
This workshop provides an opportunity for interested researchers to share ideas and findings on cross-platform data contributions. One portion in the workshop is dedicated to a hands-on session. In this session, basics of spatial data access through selected APIs and the extraction of summary statistics of the results will be illustrated.
The workshop shall focus, but is not limited to, the following topics and areas of research:
- User contribution patterns and data sharing across multiple VGI and social media platforms
- Accessing and visualization of VGI data from various platforms
- Understand differences in spatial/temporal coverage of contributions to different platforms
- Understanding how data are linked across different VGI/social media platforms
- What types of communities are evolving and emerging from VGI/social media platforms
- Investigating how cross-linked data are used in real-world applications
- Describing the effects of the growing number of VGI and social media on data quality and user behavior
- Assess the quality of cross-linked VGI
- Identifying current research questions and an emerging research agenda
