Example two
The embodiment of the invention provides a method for sending display information, wherein an execution main body of the method is a server. The terminal in the method can be a mobile terminal such as a mobile phone and a tablet personal computer, and an application program for information query can be installed on the terminal, so that information such as news, road condition information and discount information can be queried. The server may be a backend server for the application.
The process flow shown in fig. 1 will be described in detail below with reference to specific embodiments, and the contents may be as follows:
The information obtaining request may be a request message that the terminal requests the server for the presentation information related to the location.
In implementation, the terminal may be installed with an application program for information query, such as a life service application program, an instant messaging application program with a group purchase function, and the like. When a user wants to perform information query, the application program can be started, a key of a query function is clicked in a main page of the application program, the application program is triggered to load a query page, the terminal acquires current position information (which can be latitude and longitude coordinates) of the terminal, an information acquisition request is generated, the acquired current position information is carried in the information acquisition request, an account identifier of an account logged in by the user in the application program can also be carried in the information acquisition request, and then the information acquisition request is sent to a server. Correspondingly, the server receives the information acquisition request sent by the terminal, and can further analyze the information acquisition request, acquire the current position information of the terminal carried in the information acquisition request, and also acquire the account identifier in the information acquisition request.
And 102, acquiring historical position information corresponding to the account currently logged in by the terminal.
In implementation, the server may establish a location information base in which information on the location where the terminal registered for each account is located at some historical time is stored. The server can collect the location information through the application program, and the location information and the account identifier in the information acquisition request can be acquired and correspondingly recorded in the location information base each time the information acquisition request sent by the terminal is received, or the location information and the account identifier of the corresponding terminal can be automatically reported to the server by the application program when the user starts the application program and recorded in the location information base by the server, or the location information and the account identifier of the corresponding terminal can be reported by the application program according to a preset reporting period and recorded in the location information base by the server. For the case that a plurality of application programs have account association, the server can also acquire the position information of the account history time from background servers of other application programs and record the position information into the position information base.
After receiving the information acquisition request sent by the terminal, the server can acquire the account identifier carried in the information acquisition request, search corresponding position information in a position information base according to the account identifier, and perform subsequent processing by taking the searched position information as historical position information. The location information reported by the terminal is generally a longitude and latitude coordinate, and after the longitude and latitude coordinate corresponding to the account identifier is found, a geohash (an algorithm for coding the longitude and latitude coordinate in the positioning process) code of a specified digit can be performed on the longitude and latitude coordinate (the specific process is described in detail in the subsequent content), that is, the geohash code of the longitude and latitude coordinate corresponding to the account identifier is obtained. A geohash code of a given number of bits may correspond to a rectangular area on the map.
Optionally, a certain mechanism may be further configured to filter location information queried in the location information base to determine historical location information to be used, and correspondingly, the processing in step 102 may be as follows: the method comprises the steps of acquiring position information uploaded by an account currently logged in by a terminal in a preset historical time period, and determining preset number of position information with the maximum repetition times in the acquired position information as historical position information corresponding to the account.
In implementation, when the server acquires the location information corresponding to the account and establishes the location information base, the server may repeatedly record the acquired location information that appears repeatedly in a certain account, or record the number of times that the location information is repeated. When the server uses the account identifier in the information acquisition request to search the corresponding location information in the location information base, the server may acquire the number of repetitions corresponding to each found location information, and determine M (e.g., 3) location information with the highest number of repetitions as the finally selected historical location information corresponding to the account. As shown in fig. 2, i1 to i10 represent longitude and latitude coordinates corresponding to an account identifier in a location information base, A, B, C, D is a geohash code, each box represents an area corresponding to a geohash code, and the geohash codes of the longitude and latitude coordinates in the same area are the same.
And 103, determining display information corresponding to the current position information and the historical position information according to the corresponding relationship between the pre-stored position information and the display information.
The display information may be news, road condition information, discount information, and the like.
In implementation, the server may pre-establish a display information base, collect massive display information and position information corresponding to each display information, and store a corresponding relationship between the position information and the display information in the display information base. For example, in the case where the presentation information is discount information, each store may upload discount information in its store to the server and upload position information of the store at the same time. The position information acquired by the server can be longitude and latitude coordinates, and the server can correspondingly store the longitude and latitude coordinates and the display information in the display information base. After the server obtains the current position information and the historical position information, the server can inquire the display information corresponding to the position information in a display information base.
Optionally, the server may further perform a geohash code on the obtained longitude and latitude coordinates, and correspondingly store the geohash code and the display information in the display information base, where the processing procedure in step 103 may be as follows: determining a geohash code of the current location information and a geohash code of the historical location information; and determining display information corresponding to the geohash code of the current position information and the geohash code of the historical position information according to the corresponding relation between the stored geohash code of the position information and the display information.
In implementation, after the server obtains the current location information and the historical location information, the server may perform a geohash coding on the current location information and the historical location information, and then search for the display information corresponding to each geohash code in a correspondence between the geohash codes of the location information stored in the display information base and the display information, using the geohash codes corresponding to the current location information and the historical location information, respectively.
And 104, sending the determined display information to the terminal.
In implementation, after the server finds the display information, the server may send part or all of the display information to the terminal. After receiving the display information, the terminal may display the received display information in the query page of the application program. Furthermore, the user can browse the display information through the query page and select the information required by the user. The process from the server receiving the information acquisition request sent by the terminal to the server sending the presentation information to the terminal may be as shown in fig. 3.
Optionally, the server may further set an arrangement order of the display information when displayed on the terminal, and correspondingly, the processing procedure in step 104 may be as follows:
step one, obtaining the sorting weight of each piece of display information corresponding to the pre-stored current position information and historical position information.
In implementation, the server may set a ranking weight for each presentation information in the presentation information base in advance, and the ranking weight may be stored in the presentation information base and corresponds to the presentation information. For different types of display information, different setting methods can be adopted for the sorting weight, and the sorting weight can be set randomly according to requirements. For example, when the display information is discount information, the ranking weight corresponding to the discount information may be determined according to the discount rate and the present price of the product corresponding to the discount information and the purchase amount (denoted as Δ purchase amount) in a preset time period, and the calculation formula may be: the ranking weight is discount rate log (present price) Δ purchase amount. As shown in fig. 4, i1 to i12 represent longitude and latitude coordinates corresponding to a plurality of display information, each box represents an area corresponding to a geohash code, the geohash codes of the longitude and latitude coordinates in the same area are the same, and w1 to w12 represent sorting weights corresponding to each display information.
Optionally, after the first step is executed and before the second step is executed, the ranking weights of some display information may be adjusted according to a certain mechanism, and the corresponding processing procedure may be as follows: acquiring display information corresponding to a plurality of pieces of position information in the current position information and the historical position information at the same time from the display information corresponding to the current position information and the historical position information; and increasing the sorting weight of the display information according to the number of the plurality of position information corresponding to the acquired display information.
In an implementation, the same display information may be provided in different geographic locations, for example, in a case where the display information is discount information, a store to which a certain discount information belongs may be a chain store, and the location of each chain store is different, but the discount information is the same. Thus, a plurality of items of the display information are set in the display information base, and the display information corresponds to different position information in different items respectively. When the server searches for the presentation information using the current position information and the historical position information, if the same presentation information is found using a plurality of different position information, the number of the plurality of position information corresponding to the presentation information may be recorded. Then, the ranking weight of the display information is increased and adjusted according to the number, and the specific increasing manner may be set arbitrarily according to actual requirements, for example, the ranking weight may be multiplied by the number to obtain an adjusted ranking weight, or a weight adjustment coefficient may also be determined according to the number, for example, the weight adjustment coefficient is 1.5 when the number is 2, the weight adjustment coefficient is 1.8 when the number is 3, and the adjusted ranking weight is obtained by multiplying the ranking weight by the weight adjustment coefficient.
And step two, determining the display sequence information of each piece of display information according to the sequencing weight of each piece of display information.
In implementation, the presentation information may be sorted in order of descending sorting weight to determine the presentation order information corresponding to each presentation information, where the presentation order information may be a sequence number after sorting, and the like.
Optionally, the ranking weight of the display information corresponding to the current location information and the ranking weight of the display information corresponding to the historical location information may be adjusted to different degrees, and then ranking is performed, and correspondingly, the processing procedure in the second step may be as follows: and determining the display sequence information of each piece of display information according to the sequencing weight of each piece of display information, and the weight adjustment coefficient of the display information corresponding to the pre-stored current position information and the weight adjustment coefficient of the display information corresponding to the historical position information.
In implementation, a higher weight adjustment coefficient (referred to as a first weight adjustment coefficient) such as 1.2 may be set corresponding to the current location information, and a lower weight adjustment coefficient (referred to as a first weight adjustment coefficient) such as 1 may be set corresponding to the historical location information. After the ranking weight of each piece of display information is determined, the ranking weight of the display information corresponding to the current position information can be multiplied by a first weight adjustment coefficient to obtain an adjusted new ranking weight, the ranking weight of the display information corresponding to the historical position information can be multiplied by a second weight adjustment coefficient to obtain an adjusted new ranking weight, and then the display information is ranked according to the ranking weight from large to small to determine the display sequence information corresponding to each piece of display information. Therefore, the display information corresponding to the current position information can be sorted in advance. In addition, different weight adjustment coefficients can be set for the display information corresponding to different historical position information according to different generation time of the historical position information, and the weight adjustment coefficient is smaller as the generation time is earlier. Different weight adjustment coefficients can be set for the display information corresponding to different historical position information according to the distance between the historical position and the current position, and the weight adjustment coefficient is smaller when the distance is larger.
And step three, sending the determined display information and the corresponding display sequence information to the terminal.
In implementation, the server may send, according to the display sequence information, some of the determined display information and the display sequence information that is ranked in the top order to the terminal, or may send all of the determined display information and the display sequence information that is determined to the terminal. The terminal receives the display information and the corresponding display sequence information, can sort the display information according to the display sequence information, and then displays the sorted display information in the query page of the application program.
The processing procedure of the above-mentioned geohash encoding is explained in detail as follows:
the geohash code is an address code, and can encode two-dimensional longitude and latitude into a one-dimensional character string (for example, the latitude of the technical center of Shenzhen nan mountain region Feiyada (hereinafter referred to as Feiyada) is 22.538, the longitude is 113.955, and the geohash code is ws101 n). And the geohash code corresponds to a rectangular area on the map.
The following encoding process is described below as a specific example.
The latitude interval of the earth is [ -90,90], the latitude of the femto is 22.538, and the latitude 22.538 can be approximately encoded by the following algorithm (the encoding process is shown in table 1):
in step one, the interval [ -90,90] is divided into [ -90, 0], [0,90], called left and right interval, and it can be determined 22.538 that belongs to the right interval [0,90], and the label is 1.
And step two, dividing the interval [0,90] into [0,45 ], and [45,90], wherein 22.538 can be determined to belong to the left interval [0,45), and the mark is 0.
Step three, recursion above process 22.538 always belongs to a certain interval [ a, b ]. The interval a, b is always shrinking with each iteration and is approaching 22.538 more and more.
Step four, if the given latitude x (22.538) belongs to the left interval, then 0 is recorded, if it belongs to the right interval, then 1 is recorded, thus a sequence 1010000000001101 is generated as the algorithm proceeds, and the length of the sequence is related to the number of divisions given.

| (22.5330,22.5385) | (22.5330,22.5357) | (22.5357,22.5385) | 1 |
Similarly, the longitude interval of the earth is [ -180,180], the longitude of femto is 113.955, and the longitude 113.955 can be similarly approximation coded (coding process is shown in table 2), which is 1101000100001001:
TABLE 2
By the above calculation, the latitude-generated code is 1010000000001101, and the longitude-generated code is 1101000100001001. Longitude is set at even number, and latitude is set at odd number, then new string can be synthesized: 11100110000000100000000011010011.
the character string is subjected to base32 (a 32-bit encoding method) (i, l, o are removed by using numbers 0 to 9 and subtitles b to z for encoding), and 111001100000001000000000110100 is converted into decimal. The corresponding numbers are: 28, 24,1,0,1, 20. Then, the coding and decoding table (table 3) is looked up, and the corresponding base32 is coded as ws101n, and the coding is the geohash coding.

| Base 32 | h | j | k | m | n | p | q | r | s | t | u | v | w | x | y | z |
The precision of the geohash coding length can be controlled, see a comparison table of the coding length and the precision shown in table 4, when the coding length is 8, the precision is about 19 meters, when the coding length is 9, the precision is about 2 meters, and the coding length can be selected according to actual needs.
