World Geographical Ontology Model

چکیده
Recent days have witnessed an explosive growth in generating data in geographic domain which leads to increasing the applications of geographical information system (GIS). Due to this increasing of GIS, GIS faced the problem of effective management of the spatial information from different resources and in different forms. So, Geographical ontologies have been introduced to the geographical domain not only as a concept model which can represent objects on semantic and knowledge level, but also to integrate geographical data from different sources and in different forms for reasoning and to facilitate knowledge sharing, in addition to assist in recognizing spatial terms. In this research, the World geographical ontology model has been developed to meet the needs of the recognition of the terminologies and the semantic relationships between geographical terms related to any location in the world. It will enable search engine to perform a spatially aware search. The design of World ontology model has been developed based on the analysis and finding relations between different parts of World locations to adopt ontology concepts. Logical formulation has been used to describe the ontology to be able to infer more intelligent relations. Then the model has been implemented using protégé tool, a sample of related data has been collected and finally the system has been tested. Query answers integrate data from different sources.

Inferring Geographical Ontologies from Multiple Resources for Geographical Information Retrieval
Many documents that can be found in the World Wide Web include some kind of geographical information, often in an implicit way. The use of resources like gazetteers and geographical ontologies can improve the results in Geographical Information Retrieval. Unfortunately, the construction of such ontologies is a long and laborious process; therefore, building an ontology in a semi-automatical way...

متن کاملA Framework for Geographic Object-based Image Analysis (geobia) Based on Geographic Ontology
GEOBIA (Geographic Object-Based Image Analysis) is not only a hot topic of current remote sensing and geographical research. It is believed to be a paradigm in remote sensing and GIScience. The lack of a systematic approach designed to conceptualize and formalize the class definitions makes GEOBIA a highly subjective and difficult method to reproduce. This paper aims to put forward a framework ...
