Collaborative Forest Fire Fighting Decision-Making experts may come from different organizations or different fields,having different knowledge structure and preferences,which gravely hinders the effective communication in the decision-making group.In this paper,ontology was introduced in Collaborative Forest Fire Fighting Decision-Making to solve semanteme compatibility during collaborative decision-making procedure.The prevalent construction methods of domain ontology were analyzed.According to the accomplished methods and in light of engineering method and life cycle approach in software development,the construction method of forest fire ontology was presented,which includes three phases of specification,conceptualization and formalization.Taking forest fire fighting decision-making application as an orientation,according to the analysis of decision-making content and the discussion among domain experts,based on the classification system and combined structure of conception,modeling primitives including concepts,relations,functions,rules,etc were abstracted from relative fields such as forestry,meteorology,fire fighting,and geography,and shareable,comprehensible,reusable,and conception models were built.Forest fire fighting domain ontology was built with ontology modeling tools. Parsing and visualization tool of ontology was designed and developed,Semantic Network Graphic and tree diagram visualization approaches were applied to the tool,with which users can display the relationship of conceptions(such as the inheritance relationship,the relationship of classes and instance and the relationship of classes and property et al.) by realistic visualization fashion and query connotation of them.The result of research serves as a basis for the communication between different disciplines or domains for effective cooperation.That would provide a reference for study on forestry and fire fighting informatization,would provide an important way in semantic level for forest fire management and the emergency demand decision-making.
