Assessing the credibility of VGI contributors based on metadata and reverse viewshed analysis : an experiment with geotagged Flickr images
Hansi Senaratne, Arne Bröring, Tobias Schreck · KOPS (University of Konstanz) · 2013
We present an approach to determine the credibility of content provided within a visual VGI source such as Flickr. We propose analysing the variability of selected user and photo metadata of geotagged Flickr photos with the location correctness of these images, which is our reference quality measure. These observed user and photo metadata can help to infer the credibility of contributors.
