Description

Geographic position determining method and device and information pushing method and device

Technical Field

The present invention relates to the field of network technologies, and in particular, to a method and an apparatus for determining a geographic location, and a method and an apparatus for pushing information.

Background

Under the high-speed development of the current mobile internet, in order to more accurately place advertisements or push marketing information, the current position of a user needs to be sensed in real time. Therefore, to realize accurate pushing of advertisement or marketing information, it is necessary to acquire geographical location information of a user in real time, and in the related art, the acquisition means of the geographical location information of the user mainly includes installing an Application (APP) on a mobile terminal of the user and reporting the geographical location information of the user regularly through the APP.

At present, in the related art, a solution for pushing information to a user based on geographical location information of the user is implemented as follows:

firstly, periodically reporting the geographical location information of a user to an application Server (APP Server) through an APP on a mobile terminal of the user;

then, the application server caches the geographical position information of the user through a distributed message queue;

thirdly, a Location Based Service (LBS) engine in the information push system pulls the geographical position information of the user from the distributed message queue in real time, and a geographical position index is constructed in a memory;

fourthly, when a user browses a webpage on a computer or a mobile terminal or opens an APP, sending an information push request is triggered, and a browser or the APP sends the information push request;

fifthly, after a positioning engine in the information pushing system receives the information pushing request, querying a preset rule set which is in accordance with the user geographical position information through an LBS engine;

sixthly, a positioning engine in the information pushing system pushes information (such as advertisements, promotion information and the like) to a browser of the first user computer or an APP on the mobile terminal according to a pushing strategy corresponding to the preset rule set, and a webpage on the browser or the APP on the mobile terminal displays the information to the first user.

The above solutions of the related art have the following drawbacks:

1) the LBS engine strictly depends on the acquisition of the geographical position information of the mobile terminal side, and if the mobile terminal side shields the function of reporting the geographical position information, the LBS engine can directly cause that the LBS engine can not acquire the geographical position information of the user, thereby influencing the pushing of the information;

2) in a scene that a user browses a webpage by using a PC (personal computer), because a corresponding geographic position information reporting mechanism is not available, the geographic position information of the user cannot be acquired, so that information cannot be pushed according to the geographic position information of the user in the scene;

3) the geographic position information of the user has certain timeliness, and if the geographic position information reported by the mobile terminal side is overdue, the reliability of the geographic position is poor, and the accuracy of information push and the user experience are influenced through verification;

in summary, in the related art, the current geographic position of the user is determined completely by depending on the geographic position information reported by the mobile terminal side in real time, the application scenario is limited, the obtained result is poor in reliability, low in accuracy and low in coverage rate, and the information is pushed to the user based on the geographic position information reported by the mobile terminal in real time, so that the application scenario of information pushing is limited, the accuracy is low, and the user experience is also low.

The technical solution of the present application will be described below by specific examples.

Example one

A method for determining a geographic location, as shown in fig. 1, includes the steps of:

step 101, generating a geographical position index based on at least one user historical data associated with a user identifier, wherein the geographical position index comprises first information used for determining a geographical position and a mapping relation between the first information and the user identifier;

102, receiving a positioning request carrying a user identifier;

103, inquiring the geographic position index corresponding to the user identifier in the positioning request;

and 104, providing the first information to the requester of the positioning request according to the inquired geographic position index.

In the embodiment, the geographic position index is formed by combining historical data (such as transaction data, browsing data, application data and the like) of the user, when the positioning data of the user cannot be acquired or the timeliness of the positioning data of the user is insufficient, the geographic position index is inquired based on the user identification, the current geographic position of the user is determined through the first information in the geographic position index, the coverage rate, the accuracy and the reliability are higher, the limitation of a use scene is avoided, and the method is convenient and fast.

In this embodiment, the first information may be one of the following: receiving address information, Global Positioning System (GPS) information and position information corresponding to the IP address; the at least one user history data may be one of the following or any combination thereof: transaction data, application data, browsing data.

In practical applications, the transaction data may be obtained from a transaction server or an application server, or by parsing a user browsing log or an application log, and the transaction data may include user identification (such as user ID, phone number, etc. registered on an e-commerce website or an application providing a transaction service) registered by a user, personal information (such as receiving address information) provided by the user, and information (such as category, quantity, etc.) related to an article object.

In practical applications, the application data mainly refers to data generated by a user using an application program on the mobile terminal, the application data may be obtained from a server providing the corresponding application program or obtained by parsing an application program log of the user, and the application data may include user identification (such as a user ID registered by the user on the application program, a filled-in phone number, and the like) registered by the user on the application program, global satellite positioning (GPS) information, and information generated when the user uses a function (such as a map, navigation, instant messaging, shopping, and the like) provided by the application program.

In practical application, browsing data mainly refers to data generated when a user browses a webpage through a device such as a mobile terminal or a PC, the browsing data can be acquired by analyzing a user browsing log and can also be acquired from a corresponding application server, and the browsing data includes user identification (such as user ID registered by the user, Cookie ID, IP address, Mac ID and the like), access time information (such as access duration, access time period and the like), webpage related information (such as website, webpage classification and webpage content) and the like generated when the user identifies and browses the webpage.

In some implementations, the geographic location index can be generated by: acquiring the first information based on at least one user historical data associated with user identification; and generating the geographic position index by using the first information and the corresponding user identification.

In this embodiment, the user history data associated with the user identifier refers to user history data corresponding to a plurality of user identifiers representing the same user. In practical applications, the association between the user identifiers can be identified by statistically analyzing the user history data (i.e., one of the browsing data, the transaction data, or the application data) carrying the user identifiers, so as to determine which user identifiers represent the same user. For example, the browsing data of the user may be statistically analyzed, and it is determined that the same user ID corresponds to a plurality of Cookie IDs, a plurality of IP addresses, and a plurality of Mac IDs, which indicates that there is a correlation between the user ID, the plurality of Cookie IDs, the plurality of IP addresses, and the plurality of Mac IDs, and actually represents the same user.

In practical application, the user history data has certain timeliness, and the first information with poor timeliness and low use frequency is poor in reliability. Therefore, the first information may be obtained based on the user history data which is closest to the current time and has a higher usage frequency, in this embodiment, after the first information is obtained, the obtained first information may be further filtered, and the geographic position index is generated by using the filtered first information and the user identifier corresponding to the filtered first information. In this way, part of the first information with poor timeliness and low use frequency can be filtered, and the first information with high timeliness and high use frequency is selected to generate the geographic position index, so that the reliability of the geographic position index is enhanced.

In this embodiment, in the process of generating the geographic position index, the priority of the first information may also be configured. The first information may be extracted from the queried geographical location index and provided to the requester of the positioning request according to a priority of the first information in the queried geographical location index. The accuracy of the first information is indicated through the priority, and the higher the priority value of the first information is, the higher the accuracy of the first information is, so that the first information with high accuracy can be accurately locked based on the priority value to improve the accuracy of the user geographic position.

In some implementations, the configuring the priority of the first information includes one or a combination of two of: 1) when the geographic position index contains a plurality of pieces of first information, sequencing the plurality of pieces of first information in the geographic position index according to a preset rule, and configuring the priority of the first information according to the sequencing result; 2) and when the geographical position index contains one piece of first information, configuring the priority of the first information as a preset value.

In practical applications, different predetermined values may be configured for different types of first information, for example, the first information may be configured as a second predetermined value when the first information is location information corresponding to an IP address, may be configured as a third predetermined value when the first information is GPS information, and may be configured as a first predetermined value when the first information is shipping address information.

In practical application, when the plurality of pieces of first information in the geographic position index are sorted according to a predetermined rule, different predetermined rules may be adopted for sorting different types of first information. For example, the receiving address information may be sorted according to the characteristics of the receiving address information, such as the frequency of use, timeliness, and regional attributes; for GPS information, the GPS information can be sorted according to timeliness, use frequency, use duration and the like; the location information corresponding to the IP address can be sorted according to characteristics such as timeliness, use frequency, access duration, and access duration. Different priority ranges can be configured for different types of first information based on the accuracy of the different types of first information, and then specific priority values are configured based on the sorting result of the first information.

In some implementations, when the first information is shipping address information, the geographic location index may be generated by: and extracting receiving address information from the transaction data corresponding to the same user identifier, and forming the geographic position index by taking the first identifier corresponding to the user identifier as a key and the filtered receiving address information as a value.

When the receiving address information is multiple, the priority of the receiving address information can be configured according to one or more of the updating time, the geographic area attribute and the using times of the receiving address information; when the receiving address information is one, the priority of the receiving address information can be configured according to a first preset value.

In some implementations, when the first information is location information of a corresponding IP address, the geographic location index may be generated by: before generating a geographical position index, establishing an IP address information base, wherein the IP address information base comprises an IP address, position information and a mapping relation of the position information; and inquiring the position information corresponding to the IP address from the IP address information base based on the IP addresses in the browsing data corresponding to the same user identification and the access time information of each IP address, and forming the geographic position index by taking the first identification corresponding to the user identification, the access time information and the IP address as keys and the position information corresponding to the at least one IP address as values.

When the geographic position index contains two or more pieces of position information corresponding to the IP addresses, the position information can be sequenced according to the access duration of each IP address, and the priority of the position information is configured according to the sequencing result; when the geographic position index contains a piece of position information corresponding to the IP address, the priority of the position information corresponding to the IP address can be configured by a second preset value.

In some implementations, when the first information is GPS information, the geographic location index may be generated by: and forming the geographic position index by taking the first identifier corresponding to the user identifier, the access time information as a key and the GPS information as a value based on the GPS information and the access time information in the application data corresponding to the same user identifier.

When the geographic position index contains two or more pieces of GPS information, the GPS information can be sorted according to the access duration corresponding to the GPS information, and the priority of the GPS information is configured according to the sorting result; when a piece of the GPS information is included in the geographical position index, the priority of the GPS information may be further configured by a third predetermined value.

In this embodiment, the generating the geographic position index may further include: identifying associations between the user identifications in the browsing data, transaction data or application data; generating the first identifier based on the associated user identifier, the first identifier comprising a first portion and a second portion, the first portion being indicative of the user identifier type, the second portion being derived with a predefined mapping algorithm based on the content of the associated user identifier.

In some implementations, the deduplication processing may be further performed based on the associated first identifiers generated by the user identifiers of the same type. In this embodiment, the associated user identifiers of the same type refer to user identifiers from historical data of users of the same type and having relevance. For example, by statistically analyzing the browsing data of the user and determining that the same user ID corresponds to a plurality of Cookie IDs, a plurality of IP addresses, and a plurality of Mac IDs, it is described that there is a correlation between the user ID, the plurality of Cookie IDs, the plurality of IP addresses, and the plurality of Mac IDs, and that the user ID, the plurality of Cookie IDs, the plurality of IP addresses, and the plurality of Mac IDs actually represent the same user.

In this embodiment, after the geographic location index is generated, the geographic location index may be stored as offline data, for example, the offline data may be stored in a database or a memory, so as to facilitate query at any time. In practical applications, the storage of the geographic position index may be separately stored according to different forms, or may be stored together. For example, a first geographic location index may be stored in the IP address information base, a second geographic location index may be stored via a designated first database, a third geographic location index may be stored via a designated second database, and so on. The specific storage manner of the geographic location index is not limited herein.

The following describes in detail the generation process of the first identifier in this embodiment by way of example:

and generating a first identifier according to an agreed format, and mapping all user identifiers for identifying the same user to one first identifier. That is, the first identifier corresponds to a class of user identifiers of a user, which may include but is not limited to: a user ID (user ID) registered by the user, a Mobile phone number, an International Mobile Equipment Identity (IMEI), a Mac ID, a Cookie ID, and the like.

In practical application, the first identifier may be generated as follows: the first identification comprises two parts, one part is configured as an identity category identification code, and the content of the other part of the user identification is obtained by a predefined mapping algorithm. In this way, a plurality of user identifications of the same type of the same user can be mapped to one first identification. The identification code of the identity category identifies the type of the user identifier, for example, when the same user ID in the transaction data corresponds to a plurality of mobile phone numbers, the plurality of mobile phone numbers belong to a plurality of user identifiers of the same type, the plurality of mobile phone numbers are mapped to the same first identifier, a first part of the first identifier is an identification code of the identity category such as 002 indicating that the user identifier is a mobile phone number, a second part of the first identifier comprises a plurality of identifiers, each identifier corresponds to one mobile phone number, and the identifiers are obtained by a predefined mapping algorithm based on the content of the mobile phone numbers.

For example, the first identifier may be generated in the following format: a first identifier is expressed by 64-bit data, and is named as NID (normalization id), and the NID is divided into two parts: one part is the first 8 bits and is configured into an identity class identification code; the other part is the last 56 bits, and the last 56 bits are incremented from 0x 0000000001, and can be obtained by the content of the user identifier in a predefined mapping algorithm. Thus, the same kind of user identifiers of the same user can be mapped into a first identifier.

In this embodiment, after the first identifier is generated, in order to ensure that the first identifier accurately corresponds to one user, deduplication processing may be performed on the first identifier. For example, when different first identifiers are generated for a user ID and a Cookie ID of the same user, and it can be determined that the user ID and the Cookie ID have a corresponding relationship, the first identifier corresponding to the user ID is covered by the first identifier corresponding to the Cookie ID. For example, if it is found that the Cookie ID is AAA and the user ID is BBB in the account that the user S has logged in historically, it may be determined that AAA and BBB both represent the same type of user identifier of the same user S, then the first identifier NID1 whose Cookie ID is AAA may be covered by the first identifier NID2 whose user ID is BBB, and after the covering, the second part of the first identifier NID2 is mapped based on "Cookie ID is AAA" and "user ID is BBB".

In practical application, if a first identifier corresponding to a certain type of user identifier of a user already exists and the type of user identifier of the user is updated, the mapping between the user identifier and the first identifier may be updated synchronously. For example, the second part of the first identifier may be modified according to the updated user identifier, so that a mapping is established between the first identifier and the updated user identifier.

The following describes in detail the generation process of the geographic position index in this embodiment by way of example:

in practical applications, the geographic location index may exist in three forms:

1) taking the IP address as a key and the position information corresponding to the IP address as a value;

2) taking a first identifier corresponding to the user identifier as a key and taking the receiving address information as a value;

3) and taking the first identifier, the IP address and the access time as keys and taking the GPS information or the position information of the corresponding IP address as values.

The geographical position index can be generated and stored in the following way:

1) generating a first geographic location index based on the browsing data of the user:

when the user identification is a user ID, a Cookie ID or a media access control identification (Mac ID) registered on a webpage by a user, the user ID, the Cookie ID or the Mac ID has a binding relationship with an IP address; in this case, a first geographical position index may be generated using the IP address as a Key (Key) and using the position information corresponding to the IP address as a Value (Value) with the position information corresponding to the IP address as the first information. Here, the IP address may be an IPv4 address, an IPv6 address, or the like, and a specific form of the IP address is not limited herein.

In some implementations, the location information corresponding to the IP address can be obtained from the outside. For example, the location information corresponding to the IP address may be periodically obtained from a database or a server (e.g., a server of an operator) for managing the information related to the IP address.

In some implementations, the first geographic location index described above may be stored in a dedicated information repository. For example, an IP address information base may be established in which the first geographical location index is stored.

In addition, the priority assigned to the geographical location information default configuration of the corresponding IP address in the first geographical location index may also be set, for example, when the priority is 100 at most, the priority may be set to a second predetermined value by default for each first information in the first geographical location index, and the second predetermined value is 10.

Wherein, the IP address can be an IPv4 address, an IPv6 address and the like.

2) Generating a second geographic location index based on the transaction data of the user:

receiving address information corresponding to the same user identification is extracted from transaction data, and the receiving address information corresponding to the same user identification is used as first information corresponding to the user identification; inquiring a first identifier corresponding to the user identifier; and generating a second geographic position index which takes the first identifier as a key and the receiving address information as a value.

The receiving address information may include, but is not limited to, receiving address, common address, etc. provided by the user to the transaction server or the application server.

In practical application, the receiving address information is sorted according to the using times and the degree that the using time is close to the current time, part of the receiving address information is reserved according to the sorting result, and the reserved part of the receiving address information is used as first information of a user. For example, when the receiving address information exceeds a certain number, the receiving address information of the previous certain number is retained, other receiving address information is removed, and the retained receiving address information can be directly used as the first information.

The long-term unused zombie addresses may exist in the delivery address information of the user, and in order to improve the processing efficiency, after the delivery address information is extracted and before the delivery address information is sorted, the delivery address information may be coarsely filtered according to the use frequency of the delivery address information, for example, the delivery address information that has not been used within 3 months from the current time may be directly filtered. In practical application, the receiving address information can be filtered in other modes. No limitation is placed on the particular filtration conditions or filtration mode.

In practical application, the priority can be configured for each receiving address information according to the sorting. Specifically, the highest priority may be configured for the first-ranked shipping address information, the second-ranked shipping address information, the third-ranked shipping address information, and the last-ranked shipping address information. In some implementations, configuring the priority may employ setting the specific priority values in a descending order. Specifically, the second highest priority differs from the highest priority by a predetermined difference, and the third highest priority differs from the second highest priority by the predetermined difference, so that the priority is assigned to each piece of the shipping address information in such a manner that the priority in order decreases. Of course, in practical applications, the receiving address information may be configured with priority in other manners, which is not limited herein.

For example, the delivery address information which is used most recently and has the most number of uses may be ranked first, and after ranking in this manner, if the delivery address information exceeds 10, only the delivery address information ranked first 10 is retained as the first information, the delivery address information ranked first is assigned with the priority of 10, the delivery address information ranked second is assigned with the priority of 9, and the delivery address information ranked tenth is assigned with the priority of 1.

In practical application, the type of the receiving address information can be set, and the priority of the receiving address information is dynamically adjusted according to the type of the receiving address information and the attribute of the current time. For example, when the current time is holiday, the priority of the receiving address information with the type of family property is increased by a fixed value, and the priority of the receiving address information with the type of unit property is decreased by a fixed value, wherein the specific value of the fixed value can be flexibly configured according to actual needs, different values can be configured for different situations, or an empirical value can be determined based on empirical data. For example, if the current time is holiday, the receiving address information priority of the family property is increased by 1, and the corresponding receiving address information priority of the unit property is decreased by 1. If the current time is the working day, the receiving address information priority of the family property is reduced by 1, and the corresponding receiving address information priority of the unit property is increased by 1.

Here, after the delivery address information is extracted, the type of the delivery address information may be determined according to other information of the user or the area attribute of the delivery address information, for example, the area attribute of the delivery address information is default to a home property when the area attribute is a cell, and the area attribute of the delivery address information is default to a unit property when the area attribute is an office building. As another example, if the user marks the type of the shipping address information (e.g., home address, unit address) when providing the shipping address information, the type marked by the user is used as the criterion.

In practical application, when the receiving address information is taken as the first information, the second geographic position index can be generated in the following way: and forming a second geographic position index by taking the first identifier of the user as a Key and the receiving address information as Value, wherein each Value is configured with a priority, and the mapping between the Key and the Value can be one-to-one, one-to-many and the like, that is, one Key can correspond to one Value or a group of values, and each Value is receiving address information with a priority. For a group of values, the values in the group may be sorted from high to low according to priority.

3) Generating a third geographic location index based on the application data or browsing data of the user:

extracting user identification (such as user ID registered on a webpage by a user, Cookie ID on the webpage, Mac ID and the like), an IP address and access time from browsing data; inquiring a first identifier corresponding to the user identifier; inquiring the position information corresponding to the IP address; and a third geographic position index taking the first identifier + the IP address + the access time as Key and the geographic position information as Value.

In the third geographic location index with the first identifier + IP address + access time as Key and the location information corresponding to the IP address as Value, the part of the IP address in the Key may be a full-segment IP address or a partial IP address (e.g., the first two segments of the IP address). In the data with the first identifier + IP address + access time as Key and the location information corresponding to the IP address as Value, the access time in the Key may be time period information (e.g., 8:00-10:00 am), duration information (e.g., 3 hours), and the like. For example, an example of Key may be: the first identification + the first two segments of the IP address +3 hours.

When the user uses the application program of the mobile terminal, the mobile terminal collects the GPS information of the user, and the GPS information is contained in the application data of the user. Extracting user identification (such as user ID registered on an application program by a user) and access time and GPS information from the application data; if the first identifier corresponding to the user identifier already exists, the first identifier corresponding to the user identifier can be inquired; and generating a third geographic position index with the first identifier + access time as Key and the GPS information as Value.

In the third geographic location index, Key and Value may be in a one-to-one or one-to-many mapping relationship. For the case that one Key corresponds to multiple values, that is, when the values are multivalued, the values may be sorted according to the access duration, and part of the values may be reserved according to the order obtained by the sorting and the priority of the reserved values may be indicated. For example, the values are sorted according to the access duration, the first 10 values are reserved, and the priorities are configured respectively, the first Value configuration priority is 10, the second Value configuration priority is 9, the third Value configuration priority is 8, and the tenth Value configuration priority is 1.

In practical application, the browsing data of the user can be obtained by collecting the browsing logs of the same user. Application logs of a user for approximately 1 month may be collected to obtain application data for the user. And reserving a part of data with higher occurrence probability after statistics and comparison of a large amount of data, and caching the part of data. In practical application, the geographical position index can be updated by periodically re-collecting the browsing log and the application program log according to business needs, so that the geographical position index has high timeliness and accuracy.
