The invention discloses a social event detection method, device and system and a computer readable storage medium. The social event detection device comprises an information construction unit, a model output unit and an event detection unit. The social event detection system comprises an event detection module and a data storage module. The storage medium stores computer readable program codes, and when the computer readable program codes are executed, the steps of the social event detection method are realized. A heterogeneous graph is constructed according to an information data flow, a detection neural network model comprising a preset node aggregation strategy model and a meta-path aggregation strategy model is used for performing aggregation output on the heterogeneous graph, and a preset clustering method is used for clustering output results to obtain social event detection results. According to the social event detection method, device and system and the computer readable storage medium, the mining su
