Address retrieval method and device

Abstract

The invention discloses an address retrieval method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: according to a query address, retrieving to obtain an address set corresponding to the query address; analyzing the addresses in the address set, where analysis comprises text similarity analysis and further comprises at least one of spatial similarity analysis and semantic comprehension analysis; and according to an analysis result of the addresses in the address set, selecting an address serving as an optimal retrieval result from the address set, and outputting the selected address. According to the embodiment, the influence of factors such as the spatial relationship between the addresses and possible incoherence of address levels can be considered, the retrieval result is analyzed by integrating the aspects of space, text and semantic understanding, the reliability of the retrieved addresses is evaluated more comprehensively, interference of special information in the addresses is avoided, and the address with higher credibility can be obtained from the retrieval result, so that the accuracy of address retrieval is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an address retrieval method and device. Background technique [0002] In the process of address retrieval, given an address, a record that is most similar to the query is obtained by searching all records in the database, so as to obtain the coordinates, category and other information of the query address. Due to retrieval strategy issues, multiple data sources, or errors in the data itself, the above retrieval process may lead to incorrect matching. This problem is difficult to completely avoid. In order to solve the above problems, the existing solutions for address information retrieval often stay in the text At the processing level, the accuracy of address retrieval is evaluated only at the text level. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Due to the interfere...

AI Technical Summary

Problems solved by technology

[0004] Due to the interference of some numbers in the address or the very rare POI (point of interest) and other special information, the final address returned by the search and the query address have a large deviation; because the spatial relationship is not considered, it is difficult to fully evaluate the reliability of the search; because In the actual situation, the hierarchical relationship of the query address may be incoherent, and only processing at the text level has a serious impact on the understanding of semantics
