Ranking of VGI contributor reputation using an evaluation‐based weighted pagerank

The quality of volunteered geographic information (VGI) is questionable as it emerges through a diversity contributors. reputation contributor increasingly applied to VGI assessment and its assurance. Research on how measure validate reputation, however, still required. This study proposes an evaluation-based weighted PageRank (EWPR) algorithm provide ranking metric reputation. Ranking established the basis assumptions that: (a) there evaluation relationship between contributors; (b) movable within community; (c) highly active contributors are more likely have high By means case studies using OpenStreetMap, two existing methods compared with EWPR algorithm. results show that algorithms used for web pages social network participants applicable understand also applies credibility, based popular indicator quality. correlation credibility characteristics indicates useful dealing variability in VGI.
