Embodiment 1

[0049] Such as figure 2 As shown, it is a flow chart of the POI data association method proposed in Embodiment 1 of the present invention, and its specific processing process is as follows:

[0050] Step 21, perform word segmentation processing on the name of the POI data to be associated, and obtain the word segmentation that forms the name.

[0051] The POI data stored in the POI database contains multiple attribute information, namely: name, type, address, geographic coordinates, administrative division code, etc., where the name and address are text information, and geographic coordinates are latitude and longitude information, type and administrative division code for encoding information.

[0052] If it is necessary to perform data fusion between the POI database to be associated and the target POI database, preprocess the POI data to be associated in the POI database to be associated in advance, and then search for the associated POI data in the target POI database fo...

Embodiment 2

[0081] In the prior art, after the target POI data is preliminarily screened out using search keywords, the geographical distance between the POI data to be associated and each target POI data is calculated, and then the type of the POI data to be associated is matched with the type of each target POI data , and match the address of the POI data to be associated with the address of each target POI data, among the target POI data whose types and addresses are successfully matched, the target POI data with the smallest geographical distance between the POI data to be associated , confirmed as the POI data associated with the POI data to be associated. However, if there is an error in the type or address of the POI data to be associated, when the type and address of the POI data are matched, the matching result may be wrong, resulting in the final confirmation of the target POI data and the target POI data to be associated Not for the description of the same POI, so the associati...

Embodiment 3

[0119] The following example illustrates the POI data association method proposed by the embodiment of the present invention.

[0120] The name of the POI data to be associated is "Qingdao Futai Automobile Sales Co., Ltd.", and the address is "No. 25, Yinchuan West Road". First, use the pre-established POI name core word segmentation thesaurus to perform word segmentation processing on the name of the POI data to be associated , get the following 5 word segmentations: "Qingdao", "Futai", "Automobile", "Sales", "Co., Ltd.", and then use the pre-established word segmentation database corresponding to each role type to perform role analysis for each word segmentation Marking, where the role type of the participle "Qingdao" is an administrative division, the role type of the participle "Futai" is the main name, the role type of the participle "automobile" is an industry word, the role type of the participle "sales" is a modifier, and the participle The role type of "Limited Compan...

Abstract

The invention discloses a method and a device for POI (Point Of Interest) data association. The method comprises the following steps: carrying out word segmentation processing on the data of a POI to be associated to obtain segmented words forming a name; carrying out role labeling on the segmented words to obtain the role types of the segmented words; selecting segmented words with the same role types as preset role types and the maximum priority from the segmented words as search keywords according to the priority sequence of the preset role types; obtaining target POI data containing the search keywords in the name from a target POI database; determining the target POI data associated with the data of the POI to be associated from the obtained target POI data. Through the adoption of the technical scheme, the problem that the POI data association is extremely low in processing efficiency in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method and device for associating interest point data. Background technique [0002] In a geographic information system (Geographic Information System, GIS), a point of interest (Point Of Interest, POI) usually refers to a location that can be paid attention to by people. Every manufacturer that produces POI data will establish its own POI database, and the POI database stores There are massive POI data, and each POI data contains all aspects of POI information, such as name, type, address, geographic coordinates, administrative division code, etc. [0003] With the development of POI data business, manufacturers that produce POI data may cooperate with each other. The cooperation methods include: integrating POI data in POI databases of multiple different manufacturers to provide users with better POI data. Since there are associated POI data in the POI databas...
