Razonamiento espacial para determinar el dominio de un conjunto de etiquetas que representan objetos geográficosKeywords: computational and artificial intelligence, intelligent systems, knowledge acquisition, knowledge representation. Abstract: nowadays, there is much geospatial information from different sources such as satellite images, aerial photographs, maps, databases, and so on. it provides a comprehensive description of geographic objects. however, the task to identify the geographic domain to which it belongs is not simple, because this task involves semantic processing based on a conceptualization of a domain. it allows us to understand information in a way similar to how humans recognize the geographic entities and avoid vagueness. we propose a method for qualitative spatial reasoning in geospatial representations. the method is based on a priori knowledge, which is explicitly formalized through an ontology. the knowledge described in the ontology is assessed according to a set of tags that belong to any geographical domain for semantic analysis, to map those tags to concepts defined in the ontology. as a result, a set of geographic domains in order of relevance is obtained, for providing a general concept directly related to the input tags, simulating the way in which humans cognitively perceive a geographic domain in the real world.
