Research on the Event Knowledge Graph of Public Security Event Driven by Multimodal Data
[Purpose/Significance]This paper aims to explore the construction method of public security event graph based on multimodal data,excavate the evolutionary law and internal logic of multimodal public security events,achieve a deep analysis and understanding of public safety events and enhance the ability of event pre-vention and control.[Method/Process]This paper obtained multimodal public safety event data including official bulletins,news reports and journal articles.By constructing public security ontology,event extraction and event relationship extraction,the multimodal public security event graph was constructed,and the temporal evolution and causal logic analysis of public security events were carried out based on the event graph.[Result/Conclusion]The research shows that the public security event graph based on multimodal data can reveal the event logic of public security events and provide scientific basis for the prevention and response of public security events.
