Fogliaroni, Paolo; D'Antonio, Fausto; Clementini, Eliseo Data trustworthiness and user reputation as indicators of VGI quality Journal Article In: Geo-spatial Information Science, vol. 21, no. 3, pp. 213–233, 2018. Abstract | Links | BibTeX | Tags: Data quality, reputation, trustworthiness, Volunteered Geographic Information @article{fogliaroni18:213[TUW-274779],Volunteered geographic information (VGI) has entered a phase where there are both a substantial amount of crowdsourced information available and a big interest in using it by organizations. But the issue of deciding the quality of VGI without resorting to a comparison with authoritative data remains an open challenge. This article first formulates the problem of quality assessment of VGI data. Then presents a model to measure trustworthiness of information and reputation of contributors by analyzing geometric, qualitative, and semantic aspects of edits over time. An implementation of the model is running on a small data-set for a preliminary empirical validation. The results indicate that the computed trustworthiness provides a valid approximation of VGI quality. |
