For the purpose of clarity, the description is divided into the following sections: technical scheme, advantages, and specific embodiments. The specific embodiments described herein are intended for purposes of illustration only and are not intended to limit the scope of the present application. The present application can be implemented in ways other than those specifically set forth herein without departing from the spirit and scope of the present application. The following description is presented to enable any person skilled in the art to make and use the present application.

[0061] It should be noted that the relational terms herein such as first and second and the like are used solely to distinguish one from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises...

[0062] To solve the problems in the prior art, embodiments of the present application provide an information pushing method, device, equipment, storage medium and program product. First, the information pushing method provided by the embodiments of the present application is introduced.

[0063] Figure 1 is a flowchart of an information pushing method 100 provided by an embodiment of the present application. As shown in Figure 1 , an information pushing method can include the following steps: S101-S103.

[0064] S101, obtaining identity information of a target user and current position information of a vehicle.

[0065] In some embodiments, the target user can be a driver of the current vehicle or a passenger of the current vehicle. In a specific implementation scenario, the information pushing method can be applied to a vehicle-mounted device of the vehicle, and information is pushed to the corresponding vehicle-mounted device according to the identity of the user and the seat position, so that the vehicle-mounted device can implement personalized information pushing service for the driver or passenger in the vehicle. Specifically, when the target user is the driver of the current vehicle, information can be pushed to the corresponding front-row vehicle-mounted device; when the target user is the passenger of the current vehicle, information can be pushed to the corresponding rear-row vehicle-mounted device; the present embodiment is not limited herein.

[0066] The identity information of the target user can be obtained through face recognition, voice recognition, iris recognition, etc. The current location information of the vehicle can be obtained through a global positioning system of the vehicle, a navigation system of a vehicle-mounted system, etc. In an implementation scenario, the image information of the target user can be collected through an image collection device such as a camera, and then the face features of the target user are captured in the image information to perform face recognition and identify the identity of the target user. In another implementation scenario, the voice of the target user can be recorded through a sound collection device such as a microphone to perform voice recognition and identify the identity of the target user.

[0067] S102, determining, according to the identity information of the target user and the current location information of the vehicle, a set of interested information of the target user at the current location from a plurality of sets of interested information, each set of interested information being determined based on a first historical communication log set of at least one mobile device associated with the target user and a second historical communication log set of at least one vehicle-mounted device.

[0068] In some embodiments, the plurality of sets of interested information can be sets of interested information of a plurality of users at a plurality of different locations, and each user can have different interests and preferences at different locations. Therefore, when performing information pushing for the target user, the corresponding set of interested information needs to be obtained according to the context of the target user at the specific location, and then the relevant information is pushed according to the location information of the user, which can enhance the user experience.

[0069] The mobile device can include a mobile phone, a tablet computer, a smart watch, etc. The plurality of sets of interested information can be determined through the historical communication logs of the mobile device and the vehicle-mounted device of the target user. These communication logs can include search records, browsing history, preference settings, favorite content, etc. of the user. By analyzing these communication logs, the interest field and preference of the user can be determined, and thus the plurality of sets of interested information of the target user can be constructed.

[0070] S103, pushing interested information in the set of interested information to the target user.

[0071] In some embodiments, the set of interested information of the target user can be stored in a cloud database, and the preferences and location information of the user are monitored in real time through a cloud service, and then the relevant information is pushed to the target user.

[0072] The embodiment of the present application can determine the set of information of interest of the target user at the current location by combining the identity information of the target user and the current location information of the vehicle, and can accurately understand the current demand and interest of the target user. In addition, the first historical communication log set records the communication behavior of the user on the mobile device, and the second historical communication log set records the communication behavior of the user on the vehicle-mounted device. The first historical communication log set and the second historical communication log set can comprehensively reflect the behavior track and interest preference of the user, thereby improving the accuracy and comprehensiveness of the set of information of interest. By pushing the set of information of interest to the user according to the real-time location information of the user, more personalized information pushing is realized. Such personalized information pushing can improve the accuracy and relevance of information pushing, thereby improving the experience and satisfaction of the user.

[0073] In order to more accurately understand the environment and demand of the target user at present, more comprehensive and accurate information pushing is provided. The present application also provides an optional implementation manner of S102. As shown in Figure 2 S102 can specifically include the following steps: S1021-S1030.

[0074] S1021, determining a target area according to the current location information of the vehicle.

[0075] In some embodiments, the target area can be determined in the following ways:

[0076] 1. Set a preset radius range, draw a circle with the current location as the center and the range as the radius, and the area within the circle is the target area;

[0077] 2. Determine the target area within a preset distance range, which is usually a range that the user can walk or drive to reach;

[0078] 3. Determine the target area according to the block division, and determine the current block and the adjacent block as the target area;

[0079] 4. Determine the target area according to landmark information such as business district, scenic spot, etc.

[0080] S1022, screening n reference sets of information of interest matching the identity information of the target user from a plurality of sets of information of interest, wherein n is a positive integer greater than or equal to 0, and the reference set of information of interest includes any one of the plurality of sets of information of interest;

[0081] In some embodiments, the identity information of the user in each set of information of interest is matched with the identity information of the target user currently identified by traversing the plurality of sets of information of interest. Only the set of information of interest matching the identity information of the target user is retained and determined as the reference set of information of interest.

[0082] In order to improve the accuracy and speed of the reference interest information set determination of the target user, when storing the interest information set, the identity information of the user can be associated with the corresponding interest information set for storage.

[0083] S1023, m = 0, m is an integer greater than or equal to 0.

[0084] S1024, m = m + 1.

[0085] S1025, determine whether m is greater than n.

[0086] S1026, when m is not greater than n, execute S1028.

[0087] S1027, when m is greater than n, end.

[0088] S1028, determine whether the position information associated with the mth reference interest set is within the target area.

[0089] In one implementation scenario, a geofence can be used for determination. A geofence is a virtual boundary based on geographic location, and a geofence is set based on the determined target area. After obtaining the current position information through the vehicle-mounted device, it is determined whether the current position is within the geofence. If the current position is within the geofence, it can be determined that the current position is in the target area. The geofence can be circular, polygonal or custom-shaped, which is not limited here.

[0090] In another implementation scenario, a map matching algorithm can be used for determination. Specifically, the current position information is matched with the map data to determine the specific position of the current position on the map. Then the current position is compared with the target area to determine whether it is within the target area.

[0091] S1029, in the case where the position information associated with the mth reference interest set is within the target area, the mth reference interest set is determined as the interest information set of the target user at the current position, and S1024 is returned.

[0092] S1030, in the case where the position information associated with the mth reference interest set is not within the target area, S1024 is returned.

[0093] In one implementation scenario, a vehicle equipped with an in-vehicle device is driving. The in-vehicle device acquires position information every a minutes. When the in-vehicle device receives the position information, a target range is determined according to preset data, and the target range contains the current position information. Then, the in-vehicle device performs position matching between the position information of all interest information sets of a target user and the position information in the target range, and if the matching is successful, the content of the interest information set that matches successfully is pushed to the target user.

[0094] The embodiments of the present application can better understand the environment and surrounding resources of the user by updating the target area according to the current position information of the vehicle and pushing information based on the interest sets in the target area, gradually expand and improve the interest information set of the current position information of the vehicle, and improve the comprehensiveness and coverage of the interest information push.

[0095] In order to consider the communication differences of the user on different devices and in different positions, accurately establish multiple interest information sets, and further increase the accuracy of information push, the present application also provides another optional implementation manner of the information push method. As shown in Figure 3 Before the foregoing S102, the foregoing method can include the following steps: S301-S304.

[0096] S301, acquire a first historical communication log set of at least one mobile device associated with a target user, and the first historical communication log set includes a plurality of first data pairs, each of which includes a first communication log and a generation time of the first communication log.

[0097] The first historical communication log set records the communication history of the mobile device of the user. The first communication log is usually recorded by the mobile device system or application, and can be acquired from the communication core network. Specifically, the first communication log can include the communication events of the user on the mobile device, such as communication content, accessed web content, application usage, operation records, etc. The generation time of the first communication log refers to the log timestamp, that is, the time point when the communication log is created or recorded, which is used to mark the occurrence time of the communication event.

[0098] S302, acquire a second historical communication log set of at least one in-vehicle device associated with the target user, and the second historical communication log set includes a plurality of second data pairs, each of which includes a second communication log, a generation time of the second communication log, and generation position information of the second communication log.

[0099] The second historical communication log set records the communication history of the user's vehicle-mounted device. The second communication log can be obtained at the Internet of Things core network. Specifically, the second communication log can include the user's communication events on the vehicle-mounted device, such as Bluetooth connection records, telephone communication records, music playing records, navigation operation records, vehicle-mounted application use records, and the like. The generation time of the second communication log refers to the time point when the communication log is created or recorded, which is used to mark the occurrence time of the communication event. The generation location information of the second communication log refers to the location information of the vehicle when the user performs a certain communication event.

[0100] S303, according to the same generation time, the first historical communication log set and the second historical communication log set are associated and matched to obtain a total communication log set based on location, and the total communication log set includes multiple location information and a communication log subset corresponding to each location information.

[0101] The second historical communication log set includes location information, and the first historical communication log set does not include location information. The associated matching of the first historical communication log set and the second historical communication log set according to the same generation time is to integrate the information in the two sets together to form a more complete total communication log set, effectively ensuring the accuracy and integrity of the user's historical data, and further ensuring the effect and accuracy of information pushing.

[0102] S304, according to the communication log subset, a set of information of interest corresponding to the location information is determined.

[0103] The communication log subset is analyzed to understand the user's behavior and preferences at a specific location. By analyzing the behavior and preferences of the target user at different locations, personalized information pushing can be achieved, and user experience can be improved.

[0104] In the embodiments of the present application, the user's set of information of interest is associated with the user's location information, so that the vehicle-mounted device can recommend relevant sets of information of interest at a specific location according to the user's historical behavior and preferences at the specific location.

[0105] It can be understood that the first historical communication log set and the second historical communication log set are both updated in real time. A timing task triggering mechanism can be set to trigger the update operation of the corresponding log set periodically, for example, every week in the case of user activity and communication behavior change. Based on user feedback and behavior data, the total communication log set for information pushing can be continuously optimized, and the information pushing effect and user satisfaction can be improved.

[0106] In one implementation scenario, the target user is a new user of the vehicle-mounted device, and there is no second historical communication log set, i.e., the second historical communication log set is empty, and thus the total communication log set only includes the first historical communication log set. Therefore, the information push can be performed according to the first historical communication log set. Specifically, a fixed number of interesting information can be randomly pushed, or the first historical communication log set can be analyzed to push information with a higher frequency in the first historical communication log set to the target user.

[0107] In order to better understand the interests and needs of the user, and thus push information that is more in line with the interests of the user, and increase the degree of personalization and accuracy of information push, the present application further provides another optional implementation manner of S304. As shown in Figure 4 S3041-S3043.

[0108] S3041, extracting keywords of each communication log in the communication log subset.

[0109] In some embodiments, the natural language processing technology or the keyword extraction algorithm can be used to extract the keywords in the communication log.

[0110] S3042, determining corresponding interesting information according to the keywords.

[0111] By extracting the keywords and determining the interesting information, the content of the communication log can be quickly understood, and important information can be accurately captured.

[0112] In some embodiments, in a case where there is a target label word matching the keyword in the preset interest database, the interesting information corresponding to the target label word is determined.

[0113] The target label word helps to more accurately locate the interest point of the user, so as to better understand the needs of the user, provide content in line with the expectations of the user, and thus improve the user experience. After the keywords are extracted, the keywords input by the user can be matched with the label words in the interest database by using an algorithm, and the label words related to the keywords can be found. According to the matched label words, the interesting information related to the label words can be obtained from the interest database, and the information can be articles, videos, products, etc.

[0114] In addition, in a case where there is no target label word matching the keyword in the preset interest database, it is determined that the keyword has no corresponding interesting information, i.e., the communication log has no corresponding interesting information. If it is determined that a keyword has no corresponding target label word in the preset interest database, unnecessary waste of resources can be avoided, for example, the keyword does not need to be further processed or analyzed, and the computing resources and time are saved.

[0115] S3043, sort all interested information in the communication log subset according to the total reference number of the keyword from high to low, to obtain an interested information set.

[0116] In some embodiments, the total reference number can be obtained by the following method:

[0117] Extract the keywords of all communication logs in the total communication log set to generate a corpus;

[0118] Determine the total reference number of each keyword according to the first total number of each keyword appearing in the total communication log set and the second total number of each keyword appearing in the second historical communication log set.

[0119] By counting the frequency of each keyword appearing in the total communication log set and the second historical communication log set, the importance and popularity of the keyword can be determined. After that, sorting the interested information according to the frequency of the keyword, i.e. the total reference number, can make the interested information ranked in the front more representative and important, which is beneficial to subsequent interested information pushing.

[0120] In order to improve the accuracy of information pushing of the vehicle-mounted device, as shown in Figure 5 The application also provides an optional implementation of determining the total reference number, which can include the following steps: S501-S503.

[0121] S501, the first total number is weighted calculated by using a preset first weight coefficient to obtain a first reference number.

[0122] S502, the second total number is weighted calculated by using a preset second weight coefficient to obtain a second reference number, and the second weight coefficient is greater than the first weight coefficient.

[0123] S503, the sum of the first reference number and the second reference number is determined as the total reference number of the keyword.

[0124] The calculation formula of the total reference number can be expressed as: total reference number = first total number * first weight coefficient + second total number * second weight coefficient.

[0125] By assigning different weight coefficients to the first total number and the second total number of the keyword, the higher importance of the second historical communication log set of the vehicle-mounted device in the information pushing process can be reflected, so that the interested set generated according to the total communication log set is more in line with the preferences and behavior habits of the target user on the vehicle-mounted device, thereby improving the accuracy of information pushing of the vehicle-mounted device.

[0126] Based on this, the interested information in the interested information set is pushed to the user, which includes:

[0127] push the top N ranked interesting information in the set of interesting information to the user, where N is a positive integer greater than or equal to 1.

[0128] By pushing the top ranked interesting information to the user, the time cost of browsing and searching can be reduced, a faster, more accurate and high-quality information service can be provided, the most relevant and interesting information can be pushed to the user, the user can obtain more valuable information, and the user experience and satisfaction can be effectively improved.

[0129] In one implementation scenario, the user drives a vehicle, and the vehicle-mounted device is equipped with a display screen and an Internet connection function. The system pushes the interesting information in the set of interesting information within the target area to the user according to the user's location information, such as road condition information, nearby scenic spot recommendations, music playlists, etc., to improve the driving experience and safety.

[0130] In another implementation scenario, before the user drives the vehicle, when the vehicle is in a stationary state but the vehicle-mounted device is in an open state, in addition to pushing the interesting information based on the location information, several interesting information in the set of interesting information matching the user's identity information can also be pushed to the vehicle-mounted device.

[0131] It can be understood that the information pushing method can push information to the user's vehicle-mounted device through the set of interesting information, or push information to the user's mobile device through the set of interesting information. In order to improve the accuracy of information pushing, the interesting information received by the user is more in line with the user's interests. The application also provides an optional implementation of constructing an interest database. As shown in Figure 6 If the target label word matching the keyword exists in the preset interest database, the foregoing method can further include the following steps S601-S606 before determining the interesting information corresponding to the target label word.

[0132] S601, collect interesting information of a plurality of users.

[0133] The interesting information can include various types of links, such as APP links, portal website links, shopping links, social media links, game links, food links, etc. By collecting these different types of links and information, the user's interests, lifestyle and consumption habits can be more comprehensively understood, and more personalized and accurate services and pushed information can be provided to the user.

[0134] S602, obtain a plurality of third historical communication logs generated by a plurality of users on a vehicle-mounted device and a mobile device.

[0135] The third historical communication log can provide rich user communication behavior information, and is helpful to understand the social activities, communication habits and behavior characteristics of the user.

[0136] In S603, keywords in the third historical communication log are extracted, and the occurrence frequency of each keyword is counted.

[0137] In S604, keywords with top M occurrence frequencies are determined as label words, where M is a positive integer greater than or equal to 1.

[0138] The keywords with higher occurrence frequencies generally represent the behavior preferences of most users, and some popular topics or themes. Determining these keywords as label words can effectively summarize the main content of the user's interests.

[0139] In S605, for each piece of information of interest, a label word associated with the information of interest is searched from the label words.

[0140] In some embodiments, the label words help to classify and summarize the multiple pieces of information of interest, so that each piece of information of interest in the interest database is more orderly and clear. By matching the information of interest of the user with the label words, the information of interest can be quickly searched and pushed by searching the label words.

[0141] In S606, the information of interest and the corresponding label words are stored in association to obtain an interest database.

[0142] In some embodiments, when the information of interest and the label words are stored in association, a key-value pair method or an association table can be used to record the correspondence between the label words and the information of interest.

[0143] The embodiments of the present application establish an interest database by storing the label words and the information of interest in association, so that the vehicle-mounted device can quickly and accurately locate the information of interest of the user by keyword and label word matching when pushing information to the user, effectively improving the timeliness of information pushing and improving the user experience.
