A method, apparatus, device, and readable storage medium for address fuzzy matching

ActiveCN119127966Bcope well
This application discloses a method, apparatus, device, and readable storage medium for fuzzy address matching. By extracting address elements from the target address text and constructing an address graph, it utilizes a graph attention network model to extract address feature vectors that integrate address semantic and structural information, thus better handling non-standard addresses. Simultaneously, it applies a vector database to perform nearest neighbor address vector matching search, eliminating the need to consider time consumption issues. Finally, it filters the desired fuzzy matching address based on a preset threshold. This solves the technical problems of existing address matching methods, which rely on standardized address databases and manual exhaustive enumeration of address structures, making it difficult to handle non-standard addresses and resulting in limited matching accuracy. Furthermore, it addresses the technical problems of long pairwise computation time when dealing with large-scale data processing, making it difficult to adapt to all scenarios.
