Integración de información geográfica mediante el uso de técnicas de alineamiento de ontologías

Abstract

Inrecentyearstheintegrationofgeographic information has had special relevance, the idea of spatial data efficient, non- redundant and interoperable, has been assumed as a way to expand the potential of data seen as a capital of organizations. Something that shows this concern is the increasing development of initiatives such as the spatial data infrastructures SDI, the creation of the Semantic Web, the generation of standards in the process of handling or information management (ISO, OGC), among others initiatives. The problem of this integration is that geographic information sources have a high level of syntactic, semantic and structural heterogeneity. Currently the use of ontologies understood as the explicit specification of a conceptualization has become a powerful tool that attempts to unify the expression of a domain in a given context. Usually when you run the integration process of ontologies is possible to find differences in the elements that prevent the creation of relationships between ontologies. To find equivalences between elements of an ontology, have been defined ontology alignment techniques that aim to define a similarity metric between objects in order to establish parity between the concepts. The investigation has focused on identifying the various techniques of ontology alignment with particular emphasis on its use in the geographical domain, and how these techniques can contribute to the integration of information at the instance and concept in geographic information systems (GIS) orin spatial databases.
