【摘要】 提出了一种基于本体的应急测绘案例检索方法,通过分析传统的案例检索方法在语义处理方面的不足,引入本体和自然语言处理技术,实现基于语义层面的案例检索。本文构建了基于本体的应急测绘案例检索框架,构建了相应的本体库,提出了自然语言查询转换的方法和自然语言检索及排序的方案,利用案例中空间信息服务模型分析突发事件辅助决策,并通过突发事件实例分析验证了方法的可行性。更多还原

【Abstract】 This paper proposes an ontology-based emergency mapping case retrieval method. By analyzing the shortcomings of traditional case retrieval methods in semantic processing,it introduces ontology and natural language processing technology to realize case retrieval based on semantic level. In this paper,the ontology-based emergency mapping project retrieval framework is constructed,and the corresponding ontology library is constructed. The natural language query transformation method and natural language retrieval and sorting scheme are proposed. Using the spatial information service model in the case to analyze emergency decision-making. The feasibility of the method is verified by the case analysis of emergencies.更多还原
