Combining VGI with Viewsheds for Photo Tag Suggestion [PDF]
, 2012 In this research we attempt to develop an improved method for tagging of digital photos, making the tagging process simpler and more accurate for users, and thus ultimately increasing the quality of the VGI data as a whole. Our method combines Volunteered Geographic Information (VGI) in the form of tags on photo sharing websites (such as Flickr and ...

Study Three: Assessing the Impact of VGI
2014Study Two demonstrated that in a realistic use scenario, consumers are more likely to use VGI and PGI alongside each other (where available) in order to converge on a truth than to use individual VGI or PGI data sets. However, as highlighted by Rieh (2002) the way in which information is perceived by a consumer during an information search is based on ...
