Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a user screening method based on an intention label, which roughly comprises the following steps as shown in figure 1:
and step S11, receiving the user positioning request and acquiring the address parameter from the user positioning request.
And step S12, calling the Goodpastel API and the local standardized ES library to acquire a preset number of address nodes with higher similarity to the address parameters.
And step S13, calculating the distance deviation value of the longitude and latitude corresponding to each address node and the address parameter.
And step S14, selecting the address node corresponding to the minimum value in the distance deviation values as a real address and returning the real address to the user.
Fig. 2 is a schematic flow chart illustrating address matching by using a gold API and an ES library according to an embodiment of the present invention. As shown in fig. 2, when fuzzy matching is performed in step S12, the following steps may be performed:
and step S21, calling a Gaode open platform address code API, and acquiring the administrative division code, the longitude and latitude and the address grade to which the address parameter belongs.
In specific real time, a high-resolution open platform address coding API is usually called first to convert the address parameters into mars coordinates.
After receiving a plaintext address input by a user, calling a high open platform address coding API, converting the address into a Mars coordinate, such as a following 'location' field, and determining longitude and latitude information of the Mars coordinate.
“adcode”:“110108”
“street”：[]
“number”：[]
“location”：“116.308264，39.995304”
"level": "Point of interest"
Then, the mars coordinates are analyzed to obtain the administrative division code (as shown in the "opcode" field) and the address level (as shown in the "level" field) to which the address parameters belong.
And step S22, judging whether the address level corresponding field is province, city, district or unknown.
Step S23, if the address level corresponding field is not any of province, city, county or unknown, searching a preset number of address nodes with high matching degree with the address parameters in the ES address library by using the administrative division code.
For example, if the address level "field obtained by API call is not" province "," city "," district "or" unknown ", then we consider that the high resolution is successful, obtain longitude and latitude and administrative district codes, and then search for several address nodes with the highest similarity in the ES address library by using the longitude and latitude parameters in the administrative district where the node is located. When the address grade is 'province', 'city', 'district' and 'unknown', the longitude and latitude conversion matching is considered to be failed, and the result of searching the ES address base by using the address parameters is taken as the standard.
Fig. 3 is a schematic flow chart illustrating address matching by using chinese word segmentation according to another embodiment of the present invention. When fuzzy matching is performed in step S12, chinese participle matching may be used, which specifically includes the following steps:
step S31, analyzing the address parameter to obtain an administrative division corresponding to the address parameter, where the administrative division includes at least one of province, direct prefecture city, district and detail address parts.
And step S32, searching corresponding address nodes in the province and city area according to the administrative division, matching the detailed addresses with data in an ES address library through Chinese word segmentation, and calculating text similarity.
And step S33, selecting address nodes with higher text similarity and preset number.
For example, after receiving a plaintext address input by a user, firstly extracting provinces, cities, counties and the like in the input address parameters, dividing the address into province/direct administration cities, districts/counties, detailed addresses and the like, searching corresponding address node data in province/city according to administrative division names, matching the detailed addresses with data in an ES address library through Chinese word segmentation, calculating text similarity, and matching the text similarity to a plurality of address node data with the highest similarity.
The preset number may be selected to be 5, or may be set to be other values, and the embodiment of the present invention is not limited.
In one embodiment, when the determination result of step S22 in fig. 2 is yes, that is, when the address level corresponding field is any one of province, city, county and unknown, the step shown in fig. 3 may be utilized to search the ES address library for a preset number of address nodes.
After the preset number of address nodes are obtained, comparing the longitude and latitude corresponding to the address nodes with the longitude and latitude obtained by calling the Goods API, calculating a distance deviation value, and selecting the address node with the minimum distance deviation value to return to the user.
The process of the present invention is further illustrated by the following specific example:
for example, the user enters the address parameter "Yanshan Tianchi travel center, Beijing City" converted to coordinates "116.184712, 40.654428" using the God Address code API. The following information is obtained by analyzing Chinese word segmentation: beijing City and detailed Address: the Yanshan Tianchi tourist center is matched with 5 addresses with the highest similarity in the sample table, deviation values are calculated according to the obtained longitude and latitude, the address corresponding to the minimum deviation value is 'Yanshan Tianchi tourist company in Beijing city', the corresponding text similarity is 0.9, and then a standardized address is output: the similarity score of the southern 50 m Yanshan Tianchi conference center of the intersection of Changchong road and Luan Chi road in Yanqing district of Beijing: 90.
in an embodiment, the method for obtaining an address node shown in fig. 2 and the method for obtaining an address node shown in fig. 3 can be applied in combination, and the specific flow is shown in fig. 4. The detailed process refers to the processes shown in fig. 2 and fig. 3, and will not be described herein again.
