Abstract

The invention discloses a place name retrieval device which comprises: an input unit used to receive names of place names; a place name information configuration unit used to store the related information of place names into a navigation electronic map database; a word division unit used to carry out the division treatments to the names of place names in the input unit to obtain a plurality of terms; a matching unit used to find fields matched with the terms in the navigation electronic map database; a display unit used to display the related information of the fields found by the matching unit. The place name information configuration unit is adopted to store the information of place names into the navigation electronic map database, thereby being capable of retrieving according to the place names and ensuring that the retrieved information is much richer.

Description

Technical field [0001] The invention relates to the information retrieval field of a car navigation system, in particular to a place name retrieval device. Background technique [0002] Existing vehicle satellite navigation systems generally provide information retrieval and query functions. With this function, users can conveniently enter the information they want to query on the query interface, and the system will automatically query and output query results to meet user needs . Some existing retrieval devices mainly perform a single location based on indications such as the name of the point of interest, the address of the point of interest, etc. The point of interest (POI) refers to the place that the user wants to know or is about to reach, or Called the destination name. [0003] For geographical names in the usual sense, they refer to geographical names with administrative regions such as countries, provinces, cities, districts, counties, towns, villages, streets, etc., a...
