Uncertain Geoinformation Representation and Reasoning: A Use Case in LBS Integration

Abstract

Due to the fact that mobile devices are in widespread use, many applications including Location Based Services (LBS) had been involved to deliver relevant information to customers anywhere at any time and thus based on their profile and geographical position. However, with the increasing number of heterogeneous databases, many problems may arise related to (1) the interoperability of geographical databases, (2) the integration of geospatial data / metadata of the same location service, provided differently by many operators and (3) the uncertain positioning results due to GPS/Radio coverage technologies, geo coding conversion functions and mobile devices'limitations. In this paper, the `uncertainty' issues on geographic, place names and semantic details for homologous objects towards a complete map conflation were solved by our MPLoM framework (Location Integration) and our Visual Domain Ontology application (Cartographic Integration) with an extension of Web Ontology Language named CartOWL.
