Abstract

The invention provides an address search method and apparatus. The method comprises the steps of: acquiring address search request information and determining to-be-searched-for target address information contained in the address search request information; splitting the target address information into at least one piece of sub-address information, wherein the target address information is composed of a plurality of different pieces of sub-address information which are corresponding to different address types; matching the at least one sub-address information or the at least one sub-address information and the target address information with different pieces of address information is an address database , wherein each piece of address information stored in the address database contains different pieces of sub-address information forming the address information; outputting the address information with the matching rate higher that a set threshold, which is obtained through matching, as the found target address information. Thus, the accuracy for extracting target address information is improved and the address matching accuracy and address search precision are effectively improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an address search method and device. Background technique [0002] With the development of communication technology and terminal technology, more and more applications rely on mobile terminals. Especially navigation apps. For example, the user can initiate a navigation request to the mobile terminal through voice or text input, and the navigation application selects a navigation route according to the received navigation request, and pushes the selected navigation route to the user. [0003] Specifically, the ways in which a navigation application selects a navigation route according to a received navigation request include but are not limited to: [0004] When the navigation request is input in text form, the CRF (English: ConditionRandomField; Chinese: Conditional Random Field) algorithm is used to extract the address name, building name / unit name from the received na...
