Semantifying OpenStreetMap
نویسندگان
چکیده
OpenStreetMap is one of the best examples of Volunteered Geographic Information. Its success relies on the ease of use and the freedom it provides. Users are supposed to geolocate their Points Of Interest and annotate them with a tag. There is no certain vocabulary or ontology of the tags that users have to commit to. The whole tagging process is done in a bottom-up manner in which the community on a wiki basis discusses this issue. Allowing users to use tags freely increases the usability of OpenStreetMap but at the same time causes semantic interoperability problems. What is needed, is a way to structure the tags while satisfying the freedom criterion. As a solution, we suggest the alignment of the tags to well structured top level ontologies. A middle layer approach for bridging the gap between the bottom-up tags of the users and the top level Descriptive Ontology for Linguistic and Cognitive Engineering (DOLCE) is proposed. The idea of “games with a purpose” is utilized to assists non-expert users in aligning their tags to DOLCE.

With an increasing number of applications building on OpenStreetMap, data quality is becoming a pressing issue. Data provenance gives useful hints that facilitate data quality assessments based on the features’ persistence. However, this requires a detailed analysis of the editing history and the corresponding contributors. In order to make this provenance information explicit, we introduce a p...
