The embodiment of the invention provides a case analysis data processing method, apparatus and device and a readable storage medium, and the method comprises the steps: obtaining the original data ofeach case in a to-be-analyzed case set; determining feature information of each case according to the original data of each case; determining graph data of the to-be-analyzed case set according to thefeature information of each case and a preset feature information edge connection rule; obtaining metric values of the frequent sub-graphs; and determining frequent sub-graph data in the graph data of the to-be-analyzed case set according to the metric value and a predetermined frequent sub-graph mining algorithm. Based on the data of the frequent sub-graphs, the law and trend of the case can beanalyzed from multiple dimensions at the same time, so that the analysis result is more comprehensive.
