Zusammenfassung:The invention relates to a public opinion tracing method and device, electronic equipment and a storage medium, and relates to the technical field of public opinion tracing. The public opinion tracing method comprises the following steps: acquiring a local social network corresponding to a public opinion, and generating an infection sub-graph based on the local social network; establishing a search tree based on the infection subgraph; calculating a propagation center value corresponding to a node and a priori estimation value corresponding to the node by using the search tree; and tracing the public opinion according to the propagation center value and the priori estimation value, and determining a public opinion propagation source node. According to the embodiment of the invention, public opinion traceability can be realized. 本公开涉及一种舆情溯源的方法及装置、电子设备和存储介质,涉及舆情溯源技术领域。其中,所述舆情溯源的方法,包括:获取舆情对应的局域社交网络,并基于所述局域社交网络生成感染子图;基于所述感染子图建立搜索树;利用所述搜索树计算节点对应的传播中心值及所述节点对应的先验估计值;根据所述传播中心值及所述先验估计值对所述舆情进行溯源,确定所述舆情传播的源节点。本公开实施例可实现舆
