Detailed Description
In the prior art, the user behavior log generated in the terminal device is the single isolated behavior information of the user uploaded by a single application respectively. That is to say, in the prior art, a user behavior log is generated by a user corresponding to any operation applied to any one of the terminal devices, the existing user behavior log records single isolated behavior information, and there is no association between the behavior information, so that the user behavior log received by a background server of the terminal device is relatively messy and redundant, and when the user behavior is subsequently analyzed and summarized according to the existing user behavior log, the data calculation amount is relatively large, the process is relatively complicated, and the efficiency is relatively low. In order to solve the problem, the invention provides a method and a device for generating a user behavior log.
The following describes a method and an apparatus for generating a user behavior log according to the present invention in detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for generating a user behavior log according to an embodiment of the present invention. As can be seen from fig. 1, the generation method includes:
The behavior information of the user is information of the user operating various applications in the terminal device, for example, taking the case that the user watches a certain movie (subsequently, the movie is defined as a target movie), the user firstly clicks an icon of certain video software (subsequently, the video software is defined as the target video software) on a home page of the smart television, clicks a movie classification icon on a first page in the target video software, enters a movie classification page, clicks an icon of the target movie on the movie classification page, and then the user can watch the target movie subsequently. And in order to obtain a better viewing effect, after clicking the icon of the target movie, the user clicks the setting icon simultaneously in the viewing process of the target movie, and in the setting classification page, the image mode, the brightness and the contrast of the target movie are adjusted by adjusting the functional items such as the image mode, the brightness, the contrast and the like. In this process, the following behavior information is generated: the user clicks the icon of the target video software, the user clicks the movie classification icon, the user clicks the icon of the target movie, the user clicks the setting icon, and the user adjusts the image mode, the brightness, the contrast and the like.
The scene information corresponding to the behavior information of the user comprises: the generation time of the behavior information of the user, the device information of the terminal device when the user behavior occurs, and the like. The device information of the terminal device includes attribute information of the terminal device and parameter information of the terminal device, for example: when a user behavior occurs, information of application software currently running at the frontmost end in the terminal device, content currently displayed on a display screen of the terminal device, current parameter values of various functional items in the terminal device, and the like.
And 102, generating a behavior information chain according to the behavior information and scene information corresponding to the behavior information.
After the behavior information of the user and the scene information corresponding to each piece of behavior information are acquired, the generation time of the behavior information can be extracted from the scene information corresponding to each piece of behavior information, that is, the generation time of the behavior information can be determined according to the scene information corresponding to the behavior information.
After the terminal equipment is started, a user behavior log reporting service (service) is automatically started, and after the terminal equipment is started, the behavior information of the user and scene information corresponding to the behavior information are acquired in real time. For example: after the first piece of behavior information and the scene information corresponding to the piece of behavior information are obtained, the generation time of the first piece of behavior information is determined according to the scene information. The second piece of behavior information and the scene information corresponding to the behavior information are obtained, and the generation time of the second piece of behavior information is determined according to the scene information; then, calculating the interval duration of the generation time of the second piece of behavior information and the generation time of the first piece of behavior information, and comparing the size relation between the interval duration and a first preset duration; and if the interval duration is less than or equal to a first preset duration, the second piece of behavior information and the first piece of behavior information are considered to have correlation, and the second piece of behavior information and the first piece of behavior information are connected in series according to the sequence of the generation time. Then, after acquiring a piece of behavior information and scene information corresponding to the piece of behavior information and determining the generation time of the piece of behavior information according to the scene information, calculating the interval duration between the generation time of the piece of behavior information and the generation time of the previous piece of behavior information; comparing the interval duration with a first preset duration; and if the interval duration is less than or equal to a first preset duration, serially connecting the behavior information and the previous behavior information according to the sequence of the corresponding generation time, and stopping serially connecting the behavior information and the previous behavior information until the interval duration of the generation time of the behavior information and the generation time of the previous behavior information is greater than the first preset duration after acquiring a certain behavior information. Then, all behavior information before the behavior information is connected in series to form a first behavior information chain according to the sequence of the corresponding generation time, then the behavior information is used as the initial behavior information of a second behavior information chain, and the step of comparing the size relation between the interval duration between the generation time of the behavior information with the later generation time and the generation time of the behavior information before the generation time and the first preset duration and the subsequent steps are repeatedly executed until the user behavior log reporting service is stopped after the terminal device is powered off.
Based on this, the process of generating the behavior information chain according to the behavior information and the scene information corresponding to the behavior information specifically includes: acquiring the generation time of the behavior information from the scene information corresponding to the behavior information; if the interval duration of the generation time of the behavior information with the later generation time and the generation time of the previous behavior information is less than or equal to a first preset duration, serially connecting the behavior information with the later generation time and the previous behavior information in the same behavior information chain according to the sequence of the corresponding generation time; or, if the interval duration between the behavior information with the later generation time and the generation time of the previous behavior information is longer than the first preset duration, respectively connecting the behavior information with the later generation time and the previous behavior information in series in different behavior information chains.
It should be noted that, in practical applications, a series of behaviors generated by a user through continuous operation in a short time indicate that the behaviors are correlated; and in a longer interval time, two behaviors generated by the user operation indicate that the two behaviors are unrelated. For example: when a user watches TV, the user continuously operates the volume + key of the remote controller three times within one minute to adjust the volume of the TV, which means that the user continuously clicks the volume + key three times with relevance; twenty minutes after the user clicks the volume + key, the user clicks the home page key to enter the television home page, and the two unrelated behaviors are represented when the user clicks the volume + key and the user clicks the home page key. Therefore, in the embodiment of the present application, the relevance between two behaviors is determined according to the generation time of the front and back behavior information.
And 103, determining effective behavior information contained in the behavior information chain, and deleting ineffective behavior information contained in the behavior information chain.
Some behavior information is invalid behavior information in behavior information generated after a user operates an application of a terminal device, and if a user behavior log is generated by the invalid behavior information, the user behavior log has no referential property for subsequent user behavior analysis, but influences the analysis speed and reduces the efficiency. Therefore, after the behavior information chain is generated, it is necessary to determine valid behavior information included in the behavior information chain, and delete invalid behavior information included in the behavior information chain, so that when a user behavior log generated later is used for subsequent user behavior analysis, the calculated data amount can be reduced, the analysis speed is increased, and the analysis efficiency is further increased, where the invalid behavior information is all behavior information except the valid behavior information in the behavior information chain.
In specific implementation, the effective behavior information contained in the behavior information chain is determined, and the determination can be realized by the following method: determining a child behavior information chain contained in the behavior information chain, wherein the child behavior information chain contains at least two pieces of behavior information, the interval duration between the generation time of the first piece of behavior information and the generation time of the last piece of behavior information is less than or equal to a second preset duration, and all the behavior information contained in the child behavior information chain is the same; determining the last behavior information in the child behavior information chain as effective behavior information, namely if the same repeated operation is performed on the same application of the terminal equipment by a user for multiple times within a time period less than or equal to a second preset time length, so that multiple pieces of same behavior information are generated within the time period less than or equal to the second preset time length, determining one piece of behavior information with the latest time among the multiple pieces of behavior information as the effective behavior information; and for each piece of behavior information which does not belong to any one of the sub-behavior information chains in the behavior information chain, if the interval duration between the generation time of the piece of behavior information and the generation time of the next piece of behavior information is greater than or equal to a third preset duration, determining the piece of behavior information as valid behavior information.
And 104, generating scene behavior information according to the behavior information chain and scene information corresponding to the behavior information in the behavior information chain.
And after effective behavior information contained in each behavior information chain is determined, deleting invalid behavior information contained in the behavior information chain, and determining all effective behavior information contained in the behavior information chain and scene information corresponding to each effective behavior information as a piece of scene behavior information.
And 105, extracting keywords from the scene behavior information to generate a user behavior log.
In specific implementation, an open source project HanLP (han Language processing) toolkit can be adopted to extract keywords from the scenario behavior information, each piece of scenario behavior information is input into a keyword processing interface of the open source project HanLP toolkit, a series of keywords corresponding to the scenario behavior information are obtained after the scenario behavior information is subjected to keyword extraction processing, and all the keywords corresponding to the scenario behavior information are determined to be a user behavior log.
For example, taking the example that the user watches the target movie, the behavior information of the user includes: the user clicks the icon of the target video software, the user clicks the movie classification icon, the user clicks the icon of the target movie, the user clicks the setting icon, and the user adjusts the image mode, the brightness, the contrast and the like. The behavior information is connected in series to form a behavior information chain, and the behavior information is effective behavior information. The scene information corresponding to the behavior information includes: the time for the user to click the icon of the target movie is 23 points 55 minutes at night, the brightness value of the brightness item after adjustment is 40, and the contrast value of the contrast item after adjustment is 35. Then, the scenario behavior information generated by the behavior information and the scenario information corresponding to the behavior information is input to a keyword processing interface of the open source project HanLP toolkit, and after keyword extraction processing is performed, the following keywords can be obtained: the keywords can be determined as a log of user behavior by user ID, name of target movie, movie image mode, brightness of 40, contrast of 35, and time of 23 pm and 55 pm.
In addition, after each user behavior log is generated, the data persistence of the user behavior log is carried out and the user behavior log is uploaded to a background server of the terminal device, so that the behavior of the user can be analyzed and summarized according to the user behavior log stored in the background server in the following process, and each user behavior log is generated by a series of effective behavior information which is correlated with each other, so that when the user behavior log is adopted to analyze the behavior of the user, the calculated data amount can be greatly reduced, the analysis rate is improved, and the analysis efficiency is further improved.
According to the method for generating the user behavior log, the behavior information of the user and the scene information corresponding to the behavior information are obtained in real time, the behavior information which is correlated with each other is connected in series to form a behavior information chain, invalid behavior information contained in the behavior information chain is eliminated, all valid behavior information contained in the behavior information chain and the scene information corresponding to the valid behavior information are determined to be the scene behavior information, and finally the generated keywords are determined to be the user behavior log after the keyword extraction processing is carried out on the scene behavior information. Therefore, according to the method for generating the user behavior log provided by the embodiment of the invention, the generated user behavior log associates the behavior information with the association relationship together, so that the behavior information is not isolated any more, the invalid behavior information is removed, and the effectiveness of the user behavior log is improved. Therefore, on one hand, after the user behavior log is uploaded to the background server, the data redundancy of the user behavior log is reduced, and the load of the background server is reduced; on the other hand, according to the user behavior log, when the user behavior is analyzed, the processing process is simple, the data calculation amount is greatly reduced, the analysis rate is improved, and the analysis efficiency is further improved.
