| Popis: | In order to solve problems of management confusion and linkage lack of coal mine accident knowledge, a coal mine accident ontology based on formal concept analysis was constructed. Firstly, formal contexts are separately constructed based on thesaurus and text set of coal mine, and formal context of heterogeneous resources is obtained through apposition-overlap operation. Then the formal context is converted to concept lattice by use of concept lattice construction tool. Finally, concept, attribute and instance are extracted from the concept lattice to form coal mine accident ontology. The coal mine accident ontology can organize and formally express coal mine accident knowledge, and realize sharing and reuse of coal mine accident knowledge, so as to provide help for coal mine safety warning. |
