Abstract

The invention relates to a method and a device for address location. The method comprises: according to a first text address input by a user, performing geocoding in a geocoding database to obtain longitude and latitude information of the first text address; according to the latitude information of the first text address, from a point of interest (POI) database, matching to obtain at least a reference POI, the distance between the reference POI and the first text address being in a first threshold, wherein the POI data base comprises reference POIs and longitude and latitude information of the reference POIs; using the at least a reference POI to generate a verification question and displaying the question; according to a verification question feedback result of the user, verifying whether the longitude and latitude information of the first text address is correct, and performing address location according to the verification result. The method and the device for address location can improve accuracy of address location.

Description

technical field [0001] The present application relates to the technical field of location search, in particular to an address location method and device. Background technique [0002] In Internet business, it is increasingly necessary for individual users, collectives, and business users to input their own text addresses, and then use the Geocoding algorithm to resolve the actual geographic location corresponding to the text addresses from the geocoding database ( latitude and longitude). However, due to the limitations of the existing Geocoding technology, the number of PointOfInterest (POI) in the geocoding database is limited, and it is impossible to cover all the text addresses entered by the user. Moreover, the text addresses entered by the user may also be irregular. It is common to encounter text addresses that do not appear in the geocoding database. For text addresses that do not appear in the geocoding database, generally, the nearby relevant POIs are first found...
