Semantic Reference Systems for Geospatial Information (Semantische Referenzsysteme für raumbezogene Information)
Zusammenfassung der Projektergebnisse
In this project, we developed a theory and method for grounding reference systems of geospatial data, based on human attention as well as perceptual and constructive operations. The theory serves as a methodological basis for reconstructing concepts underlying geospatial data as well as for precise semantic comparisons of those concepts. In a nutshell, the approach exploits constructive definitions of geospatial concepts, e.g. road junctions, in terms of repeatable standard procedures, such as navigation manoeuvres. In this way, it supports data providers in annotating their datasets with very precise descriptions of concept provenance and data users to compare these descriptions with the concepts needed. It thus gives rise to a novel notion of semantic interoperability, based on concept reconstruction and conversation among data users and providers. It also shows how technical sensors, measurements and observations can be described in a unified human-centric framework which discloses their observation context. Furthermore and foremost, it illustrates how geospatial object concepts such as road network categories and place types can be grounded in terms of potential activities, and how these definitions can be used in order to identify and localize corresponding objects. The approach not only has the potential to improve search and annotation technology, but also inspires new applications to automatically add data, to check expectations towards and consistency of data. Application areas include semantic referencing of volunteered geographic information (VGI), geographic information retrieval (GIR), place-based information systems, as well as the Semantic Sensor Web.
