Provenance and Trust in Volunteered Geographic Information: The Case of OpenStreetMap

Keßler Carsten, Trame Johannes, Kauppinen Tomi

Zusammenfassung

We propose to use the trustworthiness of features in Open- StreetMap as a proxy function for data quality, where a feature's trust value is computed solely from its history. The trustworthiness is based on the di erent contribution patterns that can be found in a feature's history, such as rollbacks or deletions. We argue that these patterns in- uence the trustworthiness of a feature and its contributors' reputation. We discuss di erent potential implications of the patterns on trust and reputation.
