Mine production includes geological survey and excavation, and is the fundamental activity for mine enterprise. Data related to mine production are typically geospatial, showing high space, temporal complexity and multi-scale. Geo-ontology can be applied to clearly describe and formalize geo-concepts, integrate heterogeneous geo-information and share geo-knowledge. However, several problems currently exist in the constructing process of using this new technique: efficiency resulting from extensive human involvement in the building process of geo-ontology, and the low accuracy from less attention for poor data quality and semantic contexts during data integration and knowledge reasoning. Moreover, the multiple relationships of the concepts are unclear as the multidimensional attributes and association patterns of geo-concepts are not sufficiently analyzed and expressed. The geological model and semantic descriptions are problematic without dynamic trajectories for moving objects and geological events. In this study, a new semi-automatic construction method of geo-ontology was proposed, regarding to geo-contexts based on a multi-dimensional and many-valued concept lattice (MDVCL). A formal concept hierarchy was automatically generated for higher efficiency using the multidimensional and many-valued concept lattice after data pre-processing and formal context creation of geodatabase. A semantic model of the geo-context-mediated ontologies (GMO) considering both global and local conditions was then constructed by adding four indexes of geo-contexts and dynamic events with OWL (Web Ontology Language) for more accurate formalizing description. The mapping rules were discussed between the concept lattices and the ontologies, and building mappings, in order to achieve straight forward semantic information from the concept lattices. In the end, a construction process was established through three steps, including knowledge pre-processing, multidimensional and many-valued concept lattices and semantic models. A metal mine containing geographic and geological data was selected to build a vein mining ontology for model verification. The results proved that this method could focus on multiple dimensions and complex backgrounds of the data, in order to reduce the risks of semantic errors, increase accuracy and efficiency of mine production, and provide important reference for other geo-ontology domains.
