Addresses matching fuzzy index and corresponding matching method and chain-type supplement means

Abstract

The present invention relates to addresses matching fuzzy index and a corresponding matching method and a chain-type supplement means. The addresses matching fuzzy index herein establishes a set of fuzzy rules based on Chinese phonetic alphabets as well as the characteristics of the Chinese language like lots of phonetically similar words and lots of near homograph words, and a fuzzy processing is conducted on Chinese character strings by changing the same into phonetic character strings, and the fuzzy index is established. The addresses matching fuzzy index adopted in the present invention can strengthen fault tolerance of wrong words occurred in the address and obtain a fuzzy match, whereby a success rate of matching can be markedly increased. The chain-type supplement means herein can replace functions of a standard address database under certain circumstance and provide basis for connections among address factors, therefore increasing matching efficiency. The addresses matching fuzzy index and the corresponding matching method and the chain-type supplement means of the present invention overcome the problems of insufficient application of address characteristics, reduce the problem of low calculation efficiency caused by frequent traversing to the address database, and increase the success rate of matching under the premise of a guaranteed matching rate.

Description

technical field [0001] The invention belongs to the technical field of geographic information, and in particular relates to an address matching fuzzy index, a corresponding matching method and a chain supplementary mechanism. Background technique [0002] Address matching is the process of establishing a correspondence between a literal description address and its geographic location coordinates. The address matching service follows specific steps to find a match for an address. First, the address is standardized; then the server searches address matching reference data to find potential locations; assigns a score to each candidate location based on its proximity to the address, and finally The highest value matches this address. There is also a fuzzy matching method in the address matching technology, but the fuzzy matching method in the prior art is relatively simple. Some fuzzy matching technologies do not consider the use of pinyin for fuzzy matching, and the use of add...

Problems solved by technology

There is also a fuzzy matching method in the address matching technology, but the fuzzy matching method in the prior art is relatively simple. Some fuzzy matching technologies do not consider the use of pinyin for fuzzy matching, and the use of address features is not complete enough, which affects the matching success rate.

Moreover, there is no chain supplementary mechanism in the fuzzy matching method in the prior art. The fuzzy matching method in the prior art frequently traverses the address database, resulting in low operation efficiency, which makes the address matching efficiency low.
