The present application discloses a feature matching rule construction and feature matching method and apparatus, a device and a medium, which are used for improving the feature matching efficiency. In the present application, for any first element contained in each sub-rule text string, it is determined that only when the first element is different from any element contained in a current feature matching rule tree, a first node corresponding to the first element and a second node corresponding to a first logical relation word associated with the first element are established in the current feature matching rule tree, and the first node and the second node are connected. Since the feature matching rule tree of the present application does not contain repeated nodes (node groups), the rule identification information of the sub-rule text strings can share the same node (node group). During feature matching, the matching information of the same node (node group) can share the matching information between a node (node group) and account feature data, thereby avoiding repetitive calculation (matching) and improving the feature matching efficiency.
