Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
The application provides the following technical concept for solving the problem that the delivery position recommended to the user is not suitable for service providers to deliver the service in the prior art: the method comprises the steps of obtaining accurate positioning of a user terminal, determining a recommended delivery position according to an actual delivery position of a history order of the accurate positioning, and pushing the recommended delivery position to the user terminal so as to enable the recommended delivery position to be a position suitable for service providers to deliver services to users.
Those skilled in the art will appreciate that the information recommendation method of the present invention is applicable to situations including, but not limited to, a net car order driver taking a guest, a takeaway, etc. requiring a service provider to make a service delivery to a user requesting the service at a delivery location. The execution subject of the embodiment of the present invention may be a server.
Referring to fig. 3, a flowchart illustrating steps of an information recommendation method according to an embodiment of the present invention is shown, and as shown in fig. 3, the information recommendation method may specifically include the following steps:
step S301: and acquiring the current two-dimensional position coordinate of the user terminal requesting the service.
The two-dimensional position coordinate of the user terminal at present refers to the projection of the three-dimensional space position of the user terminal on the two-dimensional map. For example, if the three-dimensional spatial position of the user is 32 th building, the projection of the three-dimensional spatial position on the two-dimensional map is the 32 th building.
Therefore, the two-dimensional position coordinates where the user terminals in the same building are located can be regarded as the same.
Optionally, the two-dimensional position coordinate where the user terminal is currently located may also be a two-dimensional position coordinate corresponding to a geographic position input by the user.
Step S302: and determining a recommended delivery position according to the delivery positions of the plurality of historical orders of the two-dimensional position coordinate.
The delivery location of the historical order refers to the location in the historical order where the service provider actually made the service delivery to the user, i.e., the location suitable for the service provider to make the service delivery, rather than the order placement location originally selected by the user in the historical order. For example, if the place of ordering initially selected by the user in one historical order is "building 1 unit 101 of building 2 of the sea lake region of beijing city, the place where the service provider actually delivers the service to the user is" west gate of sea lake region of beijing city, the west gate of sea lake region of beijing city, and the place of delivery of the historical order is "west gate of sea lake region, the west gate of sea lake region of beijing city, the west gate of sea lake region, the north gate, the west gate of sea region, the north gate, and the like". Because the delivery location of the historical order is the location where the service provider actually made the service delivery to the user, the delivery location is certified as being a suitable location for making the service delivery. Therefore, the recommended delivery position determined based on the delivery positions of the plurality of historical orders can be ensured to be a position suitable for the service provider to make the service delivery.
Determining a recommended delivery position according to the delivery positions of a plurality of historical orders of a two-dimensional position coordinate where a user terminal is currently located, wherein the specific method comprises the following steps: the method comprises the steps that a user terminal obtains a current two-dimensional position coordinate and then sends the current two-dimensional position coordinate to a server, the server inquires a plurality of historical orders with the same historical position coordinate of historical positioning and the current two-dimensional position coordinate of the user terminal in historical orders, then a plurality of delivery positions of the plurality of historical orders with the same two-dimensional position coordinate are obtained, an optimal delivery position is determined according to the plurality of delivery positions, and the optimal delivery position is a recommended delivery position of the current user terminal.
For example, the two-dimensional position coordinate of the current location of the user terminal is "building 2 of the north jing sea lake region perpetual tai garden", the two-dimensional coordinate located in the historical query order by the server is also 10 orders of "building 2 of the north jing sea lake region perpetual tai garden", the actual delivery position of 7 orders among the 10 orders is "western gate of the north jing sea lake region perpetual tai garden", the actual delivery position of 2 orders is "north gate of the north jing sea lake region perpetual tai garden", the actual delivery position of 1 order is "north gate of the north sea lake region perpetual tai garden", an optimal delivery position (for example, north sea lake region perpetual tai garden west gate) is determined according to the actual delivery positions of the 10 historical orders, and the optimal delivery position is the recommended delivery position of the current user terminal. Different optimal delivery positions can be determined by different methods.
Optionally, the method for determining the recommended delivery position according to the delivery positions of the multiple historical orders of the two-dimensional position coordinate where the user terminal is currently located may be implemented by mining a corresponding relationship list between the two-dimensional position coordinate and the optimal delivery position in the historical orders in an off-line manner in advance, so that when the two-dimensional position coordinate where the user terminal is currently located is obtained, the corresponding relationship list may be directly queried, and the corresponding optimal delivery position may be determined as the recommended delivery position.
Step S303: and pushing the recommended delivery position to the user terminal.
After the recommended delivery position of the user terminal is determined, the recommended delivery position is pushed to the user terminal, so that the user can select the recommended delivery position as an order placement position.
By adopting the technical scheme of the embodiment of the application, the two-dimensional position coordinate where the user terminal requesting service is currently located can be obtained; determining a recommended delivery position according to the delivery positions of the plurality of historical orders of the two-dimensional position coordinate; and pushing the recommended delivery position to the user terminal. Therefore, the recommended delivery position pushed to the user terminal can be a position suitable for service providers to deliver the service, and therefore, when too many close candidate delivery positions of the user terminal or in a special scene, the recommended delivery position can also be pushed to the user terminal and is suitable for the service providers to deliver the service, the situation that the user does not know which delivery position should be selected or the selected delivery position is inside a building and is invisible when too many close candidate delivery positions of the user terminal are avoided, the situation that the delivery position pushed to the user is a position where the service providers cannot enter is also avoided, the user experience is improved, and the service loss of a service providing platform is reduced.
In another embodiment of the present application, determining a recommended delivery location according to the delivery location of each of the plurality of historical orders with the two-dimensional location coordinate includes: clustering delivery positions of a plurality of historical orders of the two-dimensional position coordinate; and determining the recommended delivery position according to the clustering result.
The method comprises the steps that a large amount of data are accumulated in a historical order, wherein the data comprise delivery positions, the delivery positions are associated with the order-placing two-dimensional position coordinates of a user, the optimal delivery position corresponding to the order-placing two-dimensional position coordinates of the user is found through big data clustering and association, the optimal delivery position is used as a recommended delivery position, and therefore the corresponding relation of the large amount of data, namely the order-placing two-dimensional position coordinates and the recommended delivery position, is collected according to the large amount of data in the historical order.
Referring to fig. 4, a schematic flowchart of an embodiment of a process for mining an optimal delivery location of a historical order is shown, and in this embodiment, as shown in fig. 4, the process may specifically include the following steps:
step S401: and (5) the user gives a single position for structured analysis.
The user ordering position structured analysis means that the position of ordering of the user is identified as the position of a fixed structure. For example, "building 1 unit 2 of the beijing city hai lake district yongtai garden [ district ]1 unit [ unit ]101[ room ]" is recognized as "building [ unit ]2 of the beijing city [ city ] hai lake district [ district ] yongtai garden [ district ]1 unit [ unit ]101[ room ]" by the position structured analysis ner model.
The structured position is then projected on a two-dimensional map. For example, "building No. 2 [ building ]1 unit [ unit ]101[ room ] in" beijing city [ city ] hai lake region [ district county ] immortal [ district ] and projection on the two-dimensional map is "building No. 2 in" beijing city hai lake region immortal [ building ] on the two-dimensional map. Thus, the two-dimensional position coordinates of the users who are in different units and rooms of the Yongtaiyuan No. 2 building in the Haizu district of Beijing City are all 'the Yongtaiyuan No. 2 building in the Haizu district of Beijing City'.
Optionally, the structured addresses may be subdivided into different granularities when projected on the two-dimensional map according to the amount of data and the actual demand. For example, "building [ unit ] No. 2 building [ unit ] No. 101[ room ] in" beijing city [ city ] hai lake region [ district ] No. 2 building [ building ] No. 1 "projection on two-dimensional map can be subdivided into unit level, which is" building 1 unit in "hai lake region No. 2 building" in "beijing city.
In this embodiment, the order placing position is structurally analyzed, which may be applied to a delivery position for mining a historical order to obtain a two-dimensional position coordinate corresponding to the order placing position in the historical order, or may be applied to obtain a current two-dimensional position coordinate of the user terminal. Mining the delivery position of the historical order, specifically: and acquiring a two-dimensional position coordinate of each ordering position in the historical order, and acquiring a plurality of delivery positions corresponding to the two-dimensional position coordinate. Step S402: and (5) delivering position coordinate clustering.
After obtaining a plurality of delivery positions corresponding to the two-dimensional position coordinates in the historical order, clustering the coordinates of the plurality of delivery positions corresponding to each two-dimensional position coordinate to obtain the optimal delivery position corresponding to the two-dimensional position coordinate. The optimal delivery location is the recommended delivery location. The clustering method can be used for clustering the central point, or selecting the delivery position which is closest to the average distance of all the delivery positions as a clustering result, or other general algorithms.
Therefore, the corresponding relation between the coordinates of the multiple groups of lower single two-dimensional positions and the optimal delivery positions obtained by clustering the delivery positions can be obtained through historical data.
Step S403: the delivery location is associated.
And if the coordinates of the plurality of delivery positions corresponding to each two-dimensional position coordinate are clustered, and the obtained clustering result is a specific delivery position, storing the corresponding relation between the two-dimensional position coordinate and the delivery position, wherein the corresponding relation represents that the delivery position is a recommended delivery position corresponding to the two-dimensional position coordinate.
If the coordinates of the delivery positions corresponding to each two-dimensional position coordinate are clustered, the obtained clustering result is not a specific delivery position but a coordinate. And if the coordinate is not directly used for recommending the delivery position, associating the coordinate to the delivery position, taking the associated delivery position as the recommended delivery position corresponding to the two-dimensional position coordinate, and storing the corresponding relation between the two-dimensional position coordinate and the delivery position.
In general, the unit under the user is a position such as an entrance, a door, and the like, and the room entrance and the building entrance are relatively close to each other in the vertical direction, so that the address can be refined to the unit or building granularity in the address structured analysis. If the customer order placement location is in an area that does not allow the dealer to enter, the delivery location is typically at the entrance or exit location of the area. Therefore, when the coordinates obtained by clustering are associated with the delivery position, the addresses with different granularities corresponding to the addresses can be associated with the gateway, and the closest gateway delivery position can be selected from the fine granularity to the coarse granularity.
Still taking the address "building 1 unit 2 of the yongtai garden No. 2 in hai lake district, beijing as an example, the addresses available for association include: "the unit of building No. 2 Yongtaiyuan of Haizhiguan district of Beijing City", "south door of Yongtaiyuan of Haizhiguan district of Beijing City", "north door of Yongtaiyuan of Haizhiguan district of Beijing city", etc.
By adopting the technical scheme of the embodiment of the application, the corresponding relation between a large number of ordering two-dimensional position coordinates and the recommended delivery position can be mined off-line through the distribution data accumulated in the historical orders, so that the pressure of on-line processing of the server is reduced. The order placing position of the user is structurally analyzed, and the order placing position which is not standard enough and is disordered can be converted into two-dimensional position coordinates with different granularities according to actual requirements. Then, multiple delivery positions corresponding to the same two-dimensional position coordinate can be obtained, and the multiple delivery positions are clustered to obtain a recommended delivery position. Thus, the corresponding relation between the ordering two-dimensional position coordinate and the recommended delivery position is obtained. Therefore, when the two-dimensional position coordinate where the user terminal is located currently is obtained, the corresponding relation between the single two-dimensional position coordinate and the recommended delivery position in history can be directly inquired, and the recommended delivery position pushed to the user terminal is determined.
In another embodiment of the present application, the obtaining of the two-dimensional position coordinate of the current location of the user terminal requesting the service may specifically include the following steps:
step S501: and determining the current three-dimensional space position of the user terminal according to the signal intensity of each WIFI detected by the user terminal.
The signal strength of the WIFI signal may decrease with increasing propagation distance during the spatial propagation process. According to the intensity of the WIFI signal detected by the user terminal, the distance between the user terminal and the WIFI signal emission source can be calculated. By calculating the distance between the user terminal and the plurality of WIFI signal emission sources, the three-dimensional space position of the user terminal can be calculated, and therefore accurate positioning of the user terminal is achieved. Meanwhile, the three-dimensional space position of the user terminal is calculated according to the intensity of the plurality of WIFI signals detected by the user terminal.
Step S502: and inquiring a spatial membership map according to the current three-dimensional spatial position of the user terminal so as to obtain the two-dimensional position coordinate of the user terminal.
The spatial membership map represents a parent-child relationship between each two-dimensional position coordinate and each three-dimensional spatial position, that is, a parent-child relationship representing each spatial position and an affiliated spatial position.
After the three-dimensional spatial position of the user terminal is obtained, the spatial membership map is inquired, so that the two-dimensional position coordinate where the user terminal is located can be obtained, and meanwhile, the area where the two-dimensional position coordinate where the user terminal is located is obtained.
Through the spatial membership map, the fact that the xx company is affiliated to the Yongtai garden No. 2 building can be known, and the Yongtai garden No. 2 building is affiliated to the Yongtai garden, so that the area where the user terminal is located is identified.
In another embodiment of the present application, the obtaining of the two-dimensional position coordinate of the current location of the user terminal requesting the service may specifically include the following steps:
step S601: and determining the current two-dimensional position coordinate of the user terminal according to the GPS information of the user terminal or the information of the connected base station.
If the user terminal does not start the WIFI detection permission or no WIFI signal emission source is nearby, the three-dimensional space position of the user terminal cannot be calculated according to the intensity of a plurality of WIFI signals detected by the user terminal. In this case, the two-dimensional position coordinate where the user terminal is currently located can be directly located through the user terminal GPS information or the information of the connected base station.
Even if the three-dimensional space position of the user terminal can be calculated according to the multiple WIFI signal strengths detected by the user terminal, the three-dimensional space position calculated according to the multiple WIFI signal strengths detected by the user terminal can be verified through the GPS information of the user terminal or the information of the connected base station.
Step S602: and inquiring a building outline database according to the two-dimensional position coordinate of the current position of the user terminal so as to obtain the relationship between the two-dimensional position coordinate of the current position of the user terminal and the building.
Wherein the building profile database includes profile data characterizing a planar map covered by a building. The contour data of the plane map covered by the building can be obtained through satellite photos or manually collected, which is not limited in the embodiment of the present invention.
The relationship between the two-dimensional position coordinate where the user terminal is currently located and the building may include that the two-dimensional position coordinate is inside the building, that the two-dimensional position coordinate is outside the building, that the two-dimensional position coordinate is in the middle of two buildings, and the like.
The relation between the two-dimensional position coordinate where the user terminal is located and the building is obtained, and accurate building identification can be achieved. After identifying a building, for some special scenarios, such as a hospital, it may be determined that the service provider cannot enter the area where the hospital is located.
In another embodiment of the present application, the technical means described in the above steps S501, S502, S601 and S602 may be combined as desired, for example, referring to fig. 5, a schematic flow chart for identifying accurate positioning of a building is shown, and in this embodiment, as shown in fig. 5, the following steps may be specifically included:
step S701: and (5) WIFI positioning.
And determining the current three-dimensional space position of the user terminal according to the signal intensity of each WIFI detected by the user terminal.
The method for implementing this step may be as in step S501.
Step S702: GPS information location or information location of base stations.
And determining the two-dimensional position coordinate of the user terminal according to the GPS information of the user terminal or the information of the connected base station.
The method for implementing this step may be as in step S601.
Step S703: and (6) positioning and sensing.
This step integrates the three-dimensional spatial position where the user terminal is currently located, which is obtained in step S701, and the two-dimensional position coordinate where the user terminal is currently located, which is obtained in step S702, to accurately sense the spatial position where the user terminal is currently located.
Step S704: a spatial membership map.
And inquiring the spatial membership map according to the accurately perceived spatial position of the current user terminal to acquire the two-dimensional position coordinate of the user terminal.
The method for implementing this step may be as in step S502.
Step S705: a building profile database.
And inquiring a building outline database according to the accurately perceived space position of the current user terminal to acquire the relationship between the two-dimensional position coordinate of the current user terminal and the building.
The method for implementing this step may be as in step S602.
Step S706: and identifying the buildings.
This step integrates the spatial position where the user terminal is currently located obtained in step S703, the two-dimensional position coordinate where the user terminal is located obtained in step S704, and the relationship between the two-dimensional position coordinate where the user terminal is currently located and the building obtained in step S705, so as to accurately identify the building or area where the user terminal is currently located.
By adopting the technical scheme of the embodiment of the application, the three-dimensional space position where the user terminal is located at present is determined by utilizing the signal intensity of each WIFI detected by the user terminal, and the accurate positioning of the user position can still be achieved in a place with a high-rise building. Meanwhile, WIFI signal intensity, GPS information and base station positioning are adopted, mutual verification can be achieved, and positioning accuracy is improved. Through the spatial membership map and the building profile database, buildings and areas where users are located can be accurately identified, and identification of accurate scenes is greatly improved. Therefore, on the basis of common positioning, building blocks and areas can be further determined, the coverage is larger than that of positioning perception based on wifi fingerprints, and the recognition rate of an accurate building scene is greatly improved.
And after the precise positioning of the two-dimensional position coordinate of the user is realized and the recommended delivery position corresponding to the two-dimensional position coordinate is mined through a mass of historical orders, the recommended delivery position is pushed to the user terminal.
Referring to fig. 6, a flowchart illustrating a step of pushing the recommended delivery position to the user terminal in the embodiment of the present invention is shown, and as shown in fig. 6, the step of pushing the recommended delivery position to the user terminal may specifically include the following steps:
step S801: and adding a first preset label for the recommended delivery position, and adding a second preset label for the two-dimensional position coordinate where the user terminal is located currently.
A first preset tag is added to the recommended delivery location, which may be "best delivery" or "majority choice" to help the user understand the recommended delivery location.
A second preset tag is added to the two-dimensional position coordinate where the user terminal is currently located, where the second preset tag may be a "current position," and this is not limited in the embodiment of the present invention.
Step S802: and inserting the recommended delivery position with the first preset label and the two-dimensional position coordinate with the second preset label into the top of the candidate delivery position list.
And inserting the recommended delivery position with the first preset label and the two-dimensional position coordinate with the second preset label into the first two digits of the existing candidate delivery position list so as to realize fault tolerance on the excavation of the optimal delivery position to a certain extent.
Step S803: and pushing the candidate delivery position list to the user terminal.
And pushing the candidate delivery position list inserted with the recommended delivery position and the current two-dimensional position coordinate to a user terminal so as to ensure that the user can preferentially select the recommended delivery position as an order placement position.
The pushing method of the embodiment is suitable for the initial stage. The initial stage user behavior is not sufficient, and the historical order data is not enough, so that the recommended delivery position mined according to the historical order data may not be accurate enough. In the early stage, the pushing method inserted into the top of the candidate delivery position list is adopted to carry out cold start, so that the method is very direct and efficient.
In another embodiment of the application, pushing the recommended delivery position to the user terminal may specifically include the following steps:
step S901: and inputting the recommended delivery positions and the confidence degrees thereof, and the delivery positions and the confidence degrees thereof of the plurality of historical orders into a sequencing model to obtain a sequencing result.
Wherein the confidence of one delivery location characterizes: a ratio of a number of delivery locations within a preset distance of the delivery location to a number of delivery locations of the plurality of historical orders.
For the confidence representation of one delivery position of the two-dimensional position coordinate of the user terminal, the ratio of the number of historical delivery positions corresponding to the two-dimensional position coordinate of the user terminal in the historical order to the number of all historical delivery positions corresponding to the two-dimensional position coordinate of the user terminal in the historical order is determined by taking the delivery position as the center of a circle and taking the preset distance as the radius.
For example, the current two-dimensional position coordinate of the user terminal is the Yongtai garden No. 2 building, all historical delivery positions corresponding to the Yongtai garden No. 2 building in the historical order are the Yongtai garden Western door, the Yongtai garden North door, the Yongtai garden south door, the No. 2 building 1 unit and the No. 2 building 2 unit, the preset distance is 20 meters, and the distance between the No. 2 building 1 unit and the No. 2 building 2 unit is less than 20 meters from the Yongtai garden Western door; the confidence of the west door of the eternal garden is 3/5.
The confidence of the delivery location is a floating point number smaller than 1, and may also be related to other features, such as relevance, examples, heat, type, and the like, and may also be obtained by using other calculation methods, which is not limited in this embodiment of the present invention.
And inputting the recommended delivery position and the confidence coefficient thereof as well as the delivery positions and the confidence coefficients of the plurality of historical orders into a sequencing model to obtain a sequencing result. The delivery positions and the confidence degrees of the plurality of historical orders can also be input into the sorting model to obtain a sorting result, and then the recommended delivery position is inserted into the first position of the sorting result. The sorting result is a candidate delivery position list, and the candidate delivery position list comprises the recommended delivery position and the delivery positions of a plurality of historical orders. The candidate delivery position list may further include a close range delivery position searched by using a related technology.
Step S902: and pushing the sequencing result to the user terminal.
And pushing the sequencing result to a user terminal, wherein the sequencing result comprises a plurality of delivery positions so that the user can flexibly select the order placing position.
The pushing method of the embodiment is suitable for a stage with more historical orders, a period of time samples are accumulated in the stage, and the user feeds back areas with rich accumulation. By adopting the pushing method of the embodiment, the recommended delivery position and the delivery positions of a plurality of historical orders are merged into the ranking model according to different confidence characteristics, generalization is better, and compared with the method that only the recommended delivery position is inserted into the candidate delivery position list, the plurality of delivery positions are merged into the candidate delivery position list, the method is more comprehensive.
In an embodiment of the application, the recommended delivery position can be pushed to other user terminals, where the two-dimensional position coordinate of the user terminal is located at a preset distance. For a plurality of user terminals with a preset distance, under the condition that the preset distance is smaller, the delivery positions of the user terminals are often overlapped more. Therefore, the recommended delivery position of the two-dimensional position coordinate where the user terminal is currently located can be directly pushed to other user terminals, which are away from the two-dimensional position coordinate where the user terminal is currently located by the preset distance.
By adopting the method of the embodiment, the recommended delivery position is pushed to other user terminals away from the preset distance, and the method has the following advantages: and when the two-dimensional position coordinate excavated according to the historical order and the recommended delivery position do not exist in the corresponding relation list of the two-dimensional position coordinate and the recommended delivery position where the user terminal is located currently, the recommended delivery positions of other user terminals which are away from the user terminal by a preset distance can be pushed to the user terminal. Another advantage is that the recommended delivery positions of other user terminals are directly pushed to the user terminal, so that the pressure of the server can be relieved, and the computing resources are saved.
