Problems solved by technology

However, due to the difference between the data set and domain experience in this method, most of the search terms in the LBS field correspond to less data in the Internet data, which is not statistically significant, and the recall of proper name recognition is not high enough; moreover, it is easy Due to the interference of relevant data in other fields, the accuracy rate of specific place name recognition is not high

Embodiment 1

[0051] figure 1 It is the flow chart of the identification method of the proper place name provided by this embodiment, such as figure 1 As shown, the method includes:

[0052] Step S101. Obtain the search word input by the user and the characteristic information of the user.

[0053] When map search service providers provide services such as map search and LBS positioning, they usually provide several search modes or map area operation modes, etc., so that users can choose an appropriate search mode according to the actual situation.

[0054] Search modes usually include: public transportation search, search box search or nearby search, etc. When the user performs the LBS positioning service, he inputs a search term (query) in the selected search mode. In the bus search mode, most of the search words entered by the user are bus station names, and in the nearby search and search box search modes, most of the search words entered by the user are the names of points of intere...

Embodiment 2

[0068] figure 2 It is the flow chart of the identification method of the proper place name provided by this embodiment, such as figure 2 As shown, the method includes:

[0069] Step S201. Obtain the search word input by the user and the feature information of the user.

[0070] The process of this step is the same as step S101 in the first embodiment, and will not be repeated here. Finally, the user's search term, the selected search mode, the selected map area operation mode, and the user's geographic location are obtained.

[0071] Step S202, for the search mode, determine whether the search mode is a predefined search mode, if yes, then enter step S204, determine whether the result matching the search word can be found, if yes, then enter step S206, add The credibility of the search term in question.

[0072] If a result matching the search term can be found in the search mode, and the search mode is a predefined search mode, it is considered that the search term is m...

Embodiment 3

[0086] image 3 is a schematic diagram of a device for identifying a proper place name provided in this embodiment, such as image 3 As shown, the device includes: an acquisition module 301 , a query processing module 302 and a comprehensive judgment module 303 .

[0087] The obtaining module 301 is used to obtain the search words input by the user and the characteristic information of the user.

[0088] When map search service providers provide services such as map search and LBS positioning, they usually provide several search modes or map area operation modes, etc., so that users can choose an appropriate search mode according to the actual situation.

[0089] Search modes usually include: public transportation search, search box search or nearby search, etc. When the user performs the LBS positioning service, he inputs a search term (query) in the selected search mode. In the bus search mode, most of the search words entered by the user are bus station names, and in the...

Abstract

The invention provides a method and a device for recognizing proprietary place names. The method includes acquiring a search word input by a user and feature information of the user; utilizing the search word for inquiry, and determining reliability of the search word according to inquiry results and the feature information; judging whether the reliability is larger than a preset threshold value and the search word accords with predefined name rules or not, and if yes, recognizing the search word as a proprietary place name. Compared with the prior art, the method and the device have the advantages that proprietary place name recognition in the field of LBS (location based service) is effectively performed by utilizing geographic locations and operating behavior features of users, and recall rate and accuracy rate of proprietary place name recognition of map retrieval service can be increased, so that recall rate and accuracy rate of map retrieval are increased, and processing speed of map retrieval is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of map information processing, in particular to a method and device for identifying a unique place name. 【Background technique】 [0002] With the development of social informatization, the demand for location-based services (Location Based Service, LBS) based on geographical name information is increasing. People are increasingly relying on geographic information retrieval through LBS services to quickly and accurately find the information they need. . Geographic information retrieval is based on traditional information retrieval, making full use of geographic-related information, combined with the characteristics and processing methods of geographic information, to help users complete information retrieval more effectively. [0003] Geographic information retrieval technology is mainly used to return information such as place names or geographic spatial locations of entity objects through place name retr...
