Problems solved by technology

The core part of this method extraction depends on the accuracy of the core lexicon and the non-core lexicon; and the POI dictionary includes a large number of entries (about 6000W entries), and the cost of constructing the core lexicon and the non-core lexicon is relatively high. Big

Embodiment Construction

[0037] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] One of the core ideas of the embodiment of the present invention is to extract the core segment in the POI name by removing the administrative region segment and the POI type segment from the POI name; then the core part can be accurately extracted from the POI name without manually constructing the core Dictionaries and non-core dictionaries, which can reduce the cost of extracting core parts from POI names.

[0039] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a data processing method of the present invention, which may specifically include the following steps:

[0040] Step 102, acquiring the POI name.

[0041] Step 104, removing the target segment in the POI name to obtain a core segme...

Abstract

The embodiment of the invention provides a data processing method and device, a vehicle and a server, and the method comprises the steps: obtaining a POI name, removing a target fragment in the POI name to obtain a core fragment in the POI name, wherein the target segment comprises an administrative region segment and / or a POI type segment so that the core part of the POI name can be accurately extracted. A core dictionary and a non-core dictionary do not need to be constructed manually, so that the cost for extracting the POI name core part is reduced.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method, device, vehicle and server. Background technique [0002] POI is the abbreviation of "Point of Interest", which can be translated as "Point of Interest" in Chinese. In GIS, a POI can be a house, a store, a mailbox, a bus stop, etc. [0003] Most navigation applications usually collect POI data to construct a POI dictionary, and then use the POI dictionary to realize POI query. Among them, when the navigation application performs POI query, it usually divides the query words input by the user, and then matches each word segmentation with the POI dictionary to obtain multiple query results; and then displays the multiple query results with the highest frequency to the user. ;The user needs to select one of the query results from multiple query results; and the multiple query results with the highest frequency may not be the results that t...
