Data matching method and device, equipment, storage medium and program product

The invention discloses a data matching method and device, equipment, a storage medium and a program product. The method comprises the following steps: acquiring a target data structure corresponding to a target data set and to-be-matched data structures corresponding to at least two to-be-matched data sets; performing node matching on the target data structure and the to-be-matched data structure to obtain a matching cost between the target node and the to-be-matched node; according to the matching cost, determining at least two prediction structure editing distances between the target data structure and the to-be-matched data structure; on the basis of the predicted structure editing distance, determining an operand required for modifying the target data structure into the to-be-matched data structure; and according to the operand, determining at least two real structure editing distances between the target data structure and the to-be-matched data structure, and according to the at least two real structure
