基于形式概念分析的灾害应急知识模型研究——以灾害应急专题图组为例

Research on Knowledge Model of Disaster Emergency Response Based on Formal Concept Analysis: A Case Study of Disaster Emergency Thematic Map Groups

灾害应急知识模型是开展灾害应急工作的知识载体和行动依据,现有模型无法从复杂数据中快速发现灾害应急知识之间的概念关联关系。形式概念分析(Formal Concept Analysis,FCA)是进行数据分析和知识表达的有力工具,基于FCA的灾害应急知识模型旨在为灾害应急知识理论和关键技术研究提供知识模型的支撑。该文以FCA理论为基础,从灾害应急知识的形式背景、概念格和蕴含关系集三方面建立了灾害应急知识模型,并通过格上作业发现模型内概念的关联关系;以部分灾害应急专题图组作为输入,基于Concept Explorer平台实现了该模型在正向形式和对偶形式下灾害应急知识的探究实验,验证了模型的可行性及有效性。

Disaster emergency response knowledge model is the knowledge carrier and action basis for disaster emergency response.The existing models can not quickly discover the conceptual correlation between disaster knowledge from complex data.Formal concept analysis (FCA) is a powerful tool for data analysis and knowledge representation.The FCA-based disaster emergency response knowledge model can provide support for disaster emergency response knowledge theories and key technologies.Based on the FCA theory,this paper established a disaster emergency response knowledge model considering the formal context,the concept lattice and the implication relation set,and discovered the association relationship of concepts through lattice operations.Taking some disaster emergency thematic map groups as input,based on the Concept Explorer platform,the experimental exploration of the proposed model under the positive form and the dual form was realized,and the feasibility and effectiveness of the model were verified.
