Problems solved by technology

[0004] The main disadvantage of the existing schemes is that the coverage of POI name characteristics is insufficient, that is, the artificial normative evaluation rules can only cover part of the POI naming norms, and the iterative cost of the scheme is high when the normative evaluation is performed based on the artificial rules. For example, it is necessary to When changing the existing rules, it needs to invest a lot of labor and time costs, and it is not easy to maintain

Abstract

The embodiment of the invention discloses a POI name normalization evaluation method, device and equipment and a storage medium. The method comprises the steps that feature analysis is conducted on ato-be-evaluated POI name, description features of the to-be-evaluated POI name are obtained, and the description features comprise basic features of the POI name, word features of words in the POI name and part-of-speech features of the words in the POI name; a pre-trained POI name evaluation model is utilized to determine the feature type to which the description feature of the POI name to be evaluated belongs, and normalization of the POI name to be evaluated is determined based on the feature type, the feature type comprising a standard feature type and a non-standard feature type. According to the embodiment of the invention, the normalization of various POI names in the map intelligence information can be automatically evaluated, the evaluation efficiency is improved, and the maintenance cost of POI name normalization evaluation is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of map data processing, and in particular to a POI name normative evaluation method, device, device and storage medium. Background technique [0002] For different map products, there are different requirements for the normativeness of Point of Interest (POI) names, and only POI names that meet the normative requirements are applicable in current map products. [0003] At present, to determine whether a POI name meets the name normative requirements of a specific map product, the technicians of the product line and production line summarize a series of POI naming rules and cases based on experience, and then combine the production specifications of map data to determine the man-made Standardize the evaluation rules to judge whether the collected POI names meet the normative requirements of the current map. [0004] The main disadvantage of the existing schemes is that the coverage ...
