基于事件本体的地震知识库构建研究

Research on the Earthquake Event Knowledge Base Construction Based on Event Ontology

[目的/意义]构建地震事件本体模型与地震事件知识库,揭示地震事件动态演变过程,为地震事件知识组织提供新的思路,为地震应急管理提供支持与辅助。[方法/过程]利用自然语言处理方法对采集的地震事件数据进行处理;依据本体建模方法,基于事件本体模型与灾害事件链式演变关系构建地震事件本体模型;运用Protégé和Neo4j开发地震事件本体和知识库。[结果/结论]实验结果表明,所构建的本体模型能够用于对地震事件的表示与描述,实现地震知识库的知识推理、知识检索与可视化分析功能,为地震事件知识获取与地震应急管理提供支持。

[Purpose/Significance]In response to the inadequacy of existing seismic ontologies in providing a comprehensive description of the dynamic evolution,it develops a seismic event ontology model and knowledge base based on event ontology and domain knowledge ontology in order to provide new ideas for earthquake event knowledge organization,and offer support for the emergency management.[Method/Process]First,it utilized natural language processing methods to collect and process data related to earthquake events.Second,it constructed the earthquake event ontology model and knowledge base based on event ontology and chain-typed evolution relationship of disaster events.Finally,it employed Protégé and Neo4j for knowledge retrieval and visualized analysis.[Result/Conclusion]The research findings indicate that the constructed ontology model is suitable for the representation and description of earthquake events.It can realize the knowledge reasoning,retrieval,and visualization of the earthquake knowledge base and provide the assistance and support for earthquake knowledge acquisition and earthquake emergency management.
