In the above operating environment, the present application provides a method of generating a geofence as shown in fig. 2. Fig. 2 is a flowchart of a method for generating a geo-fence according to a first embodiment of the present invention.

Step S201, target text information is obtained, where the target text information is used to describe a boundary of a target area.

Specifically, target text information describing the boundary of the target area is obtained, for example, xx adjusts the following areas into a sealed control area: the Dong Feng is in the area of the two routes of the fluid preparation from the north and the east of the fluid preparation from the south and the east of the New Tian and the West and the Keyuan.

For example, the name of the target geographic entity and the azimuth information corresponding to the target geographic entity shown in fig. 3, the east Feng great road-the north, the east Feng two roads-the south, the east Feng new heaven and earth-the west, and the science source four roads-the east.

Specifically, the geo-fence corresponding to the target text information is obtained according to the latitude and longitude information and the azimuth information. For example, fig. 4 is a schematic diagram of a geo-fence corresponding to the target text information.

Through the steps S201 to S204, the name of the target geographic entity and the azimuth information corresponding to the target geographic entity are obtained by using the target text information, then the longitude and latitude information of the target geographic entity is obtained according to the name of the target geographic entity, and finally the geo-fence corresponding to the target text information can be accurately obtained according to the longitude and latitude information and the azimuth information of the target geographic entity, so that the geo-fence is prevented from being determined in a manual mode, and the efficiency of obtaining the geo-fence is improved.

Optionally, in the method for generating a geo-fence provided in the first embodiment of the present invention, the processing the target text information, and determining the name of the target geographic entity and the azimuth information corresponding to the target geographic entity on the boundary includes: extracting information of the target text information through a preset algorithm to obtain the name of the target geographic entity; and obtaining the azimuth information corresponding to the name of the target geographic entity from the target text information through a second preset algorithm according to the regular expression of the azimuth information.

Specifically, information extraction is performed on the target text information through a preset algorithm to obtain the name of the target geographic entity. And then, acquiring a regular expression of the orientation information, and obtaining the orientation information corresponding to the name of the target geographic entity from the target text information through a second preset algorithm according to the regular expression. It should be noted that the first preset algorithm and the second preset algorithm may be the same algorithm or different algorithms. The first preset algorithm may be the BilSTM-CRF algorithm. The BilSTM-CRF algorithm: a Bidirectional Long-Short-Term Network with a Conditional Random Field Layer, a Bidirectional Long-Short-Term Memory Network with a CRF Layer, and one of deep learning models is labeled with a sequence. Through the steps, the name of the target geographic entity and the azimuth information corresponding to the name of the target geographic entity can be accurately obtained from the target text information, and therefore the accuracy of obtaining the geo-fence is improved.

Optionally, in the method for generating a geo-fence provided in an embodiment of the present invention, determining latitude and longitude information of the target geo-entity according to the name of the target geo-entity includes: obtaining a POI database, wherein the POI database comprises: the name of the entity point, the address information of the entity point and the longitude and latitude information of the entity point; obtaining a road network library, wherein the road network library comprises: the method comprises the following steps of (1) obtaining a road name, address information of a road, longitude and latitude of a road starting point and longitude and latitude of a road finishing point; and determining the longitude and latitude information of the target geographic entity according to the POI database, the road network database and the name of the target geographic entity.

Specifically, a POI database and a road network database are obtained. The POI database contains longitude and latitude information of geographic entity points, and the road network database contains longitude and latitude information of roads, namely the longitude and latitude of a road starting point and the longitude and latitude of a road finishing point. And then, acquiring the longitude and latitude information of the target geographic entity through the POI database, the road network database and the name of the target geographic entity. The longitude and latitude information of the target geographic entity can be accurately obtained through the POI database and the road network database, and the geographic fence corresponding to the target text information can be accurately obtained through the longitude and latitude information.

Optionally, in the method for generating a geo-fence according to the first embodiment of the present invention, determining longitude and latitude information of the target geographic entity according to the POI database, the road network database, and the name of the target geographic entity includes: determining a type of the target geographic entity, wherein the type is one of: solid points and roads; if the type of the target geographic entity is an entity point, acquiring longitude and latitude information of the target geographic entity in the POI database through a third preset algorithm; and if the type of the target geographic entity is a road, acquiring the longitude and latitude information of the target geographic entity in a road network library through a preset algorithm IV.

Specifically, when determining longitude and latitude information of a target geographic entity, first, a type of the target geographic entity is determined, where the type of the target geographic entity is an entity point and a road. For example, the new Fengdong is the point of the entity and the branch of the country is the road. The longitude and latitude information contained in the POI database and the road network database is specific to different types of target geographic entities, so that the target geographic entities are classified, and when the types are entity points, the longitude and latitude information of the target geographic entities is obtained from the POI database; and when the type is a road, acquiring the longitude and latitude information of the target geographic entity from the road network library. Through classifying the target geographic entities, the efficiency of acquiring longitude and latitude information is improved, and the efficiency of acquiring the geographic fence is further improved.

Optionally, in the method for generating a geo-fence provided in the first embodiment of the present invention, if the type of the target geographic entity is an entity point, obtaining latitude and longitude information of the target geographic entity in the POI database through a third preset algorithm includes: acquiring a geographic entity list from a POI database based on a fuzzy search algorithm according to the name of a target geographic entity, wherein the geographic entity list is composed of the name of an initial geographic entity and longitude and latitude information corresponding to the initial geographic entity; and obtaining the longitude and latitude information of the target geographic entity through a third preset algorithm according to the name of the target geographic entity and the name of the initial geographic entity.

Specifically, obtaining longitude and latitude information of the target geographic entity from the POI database includes first obtaining a geographic entity list from the POI database through a fuzzy algorithm, for example, as shown in fig. 5, a schematic diagram of the geographic entity list. And then, obtaining the longitude and latitude information of the target geographic entity from the geographic entity list through a third preset algorithm. The matching accuracy of the longitude and latitude information of the target geographic entity is ensured through the steps. It should be noted that the preset algorithm three may be an ESIM algorithm, which is: an Enhanced Sequential Inference Model, a commonly used short text matching deep learning Model algorithm.

Optionally, in the method for generating a geo-fence provided in the first embodiment of the present invention, obtaining latitude and longitude information of the target geographic entity through a third preset algorithm according to the name of the target geographic entity and the name of the initial geographic entity includes: acquiring context information of target text information; according to the context information, performing cross calculation on the name of the target geographic entity and the name of the initial geographic entity through a third preset algorithm to obtain a plurality of similarity values, wherein the similarity values represent the similarity between the name of the target geographic entity and the name of the initial geographic entity; and taking the longitude and latitude value of the initial geographic entity with the highest similarity as the longitude and latitude information of the target geographic entity.

Specifically, when longitude and latitude information of a target geographic entity is obtained through a third preset algorithm, context information of target text information is obtained first, where the context information is context information of the target text information, and for example, xx city adjusts the following areas to be sealed and controlled areas: the east Feng Dazhu is in the north, the east of the Feng is in the south, the east of the Feng is in the west, and the east of the Feng is in the four ways of the West and the Keyuan. Through the context information, when the longitude and latitude information of the target geographic entity is determined, only the target geographic entity in xx city needs to be considered, so that some invalid longitude and latitude information can be avoided. Then, the names of the target geographic entities and the name of the initial geographic entity are cross-calculated by a third preset algorithm, so as to obtain similarity values of the names of the target geographic entities and the name of the initial theoretic entity, for example, the data of 0.99, 0.90, 0.42, etc. in fig. 5 are the similarity values. And finally, selecting the longitude and latitude value of the initial geographic entity with the highest similarity value as the longitude and latitude information of the target geographic entity. The specific steps for obtaining the longitude and latitude information of the target geographic entity from the road network library are consistent with the above steps, and are not repeated here.

Through the steps, the longitude and latitude information of the target geographic entity can be quickly and accurately obtained, and the efficiency of obtaining the geographic fence is improved.

Optionally, in the method for generating a geo-fence provided in the first embodiment of the present invention, determining, according to the latitude and longitude information and the azimuth information of the target geographic entity, the geo-fence corresponding to the target text information includes: obtaining a target connection strategy through a fifth preset algorithm according to the longitude and latitude information and the azimuth information of the target geographic entity; connecting the longitude and latitude information of the target geographic entity according to a target connection strategy to obtain a longitude and latitude polygon; and taking the longitude and latitude polygon as the geo-fence corresponding to the target text information.

Specifically, the obtained longitude and latitude information and the azimuth information are input into a fifth preset algorithm, the fifth preset algorithm obtains a connection strategy (namely the target connection strategy) according to the information, and then the longitude and latitude information is connected according to the connection strategy to obtain a longitude and latitude polygon, wherein the longitude and latitude polygon is the geo-fence corresponding to the target text information. By means of this geo-fence it is possible to quickly and accurately determine whether a point (person/POI) is within the area. It should be noted that the preset algorithm v may be a Jarvis algorithm (also called a volume wrapping algorithm), as shown in fig. 6, which is a schematic diagram of obtaining a longitude and latitude polygon through the Jarvis algorithm. In fig. 6, P is the starting point of the longitude and latitude polygon, l represents the next point to be connected, and the longitude and latitude polygons can be obtained by connecting in sequence according to the sequence shown in fig. 6.

The name of the target geographic entity and the azimuth information corresponding to the target geographic entity are obtained through the target text information, then the longitude and latitude information of the target geographic entity is obtained according to the name of the target geographic entity, and finally the geographic fence corresponding to the target text information can be accurately obtained according to the longitude and latitude information and the azimuth information of the target geographic entity, so that the geographic fence is prevented from being determined in a manual mode, and the effect of improving the efficiency of obtaining the geographic fence is achieved.

Fig. 7 is a flowchart illustrating an alternative geo-fence generation method according to an embodiment of the present disclosure. The description text information of the geo-fence is subjected to three steps of slot filling, entity linking and convex hull calculation to obtain the geo-fence. The slot filling refers to obtaining the name of the target geographic entity and the azimuth information corresponding to the target geographic entity through the description text information. Entity linking refers to obtaining latitude and longitude information of a target geographic entity. And the convex hull calculation means that a longitude and latitude polygon is obtained through the longitude and latitude information and the azimuth information, namely, the geo-fence corresponding to the description text information is described.
