Abstract：In recent years,temporal knowledge graphs have garnered significant attention from both academia and industry,emerging as a major research hotspot.Unlike the traditional knowledge graph,the temporal knowledge graph embed temporal information,enabling representation of temporal relationship and causal relationships,describe the laws of relationship changes and event evolution patterns,and can serve as a knowledge base that can perceiving temporal information and causal laws.This paper primarily reviews the construction technologies of temporal knowledge graph.Firstly,the article introduces the definition and construction process of temporal knowledge graph.Secondly,it sorts out the research progress of key technologies such as temporal knowledge extraction,temporal knowledge embedding,and temporal logic reasoning in the process of temporal knowledge graph construction,analyzes its development status and points out its advantages and disadvantages.Finally,presents the multilevel decision of aluminum electrolysis alumina concentration multi-granularity knowledge graph construction and application case,the application prospects of temporal knowledge graph in process industry are prospected.
