The inventor of the present invention finds in the research process that when recommending a corresponding media file for a user, the media file recommending apparatus can recommend the media file for the user according to the media file of the user play history information. However, the user play history information cannot reflect the current state and the current scene of the user. For example, when a user gets up in the morning and watches a news video, and starts the video playing application before sleeping at night, if the news video is played according to the history, the news video is recommended to the user. However, according to the scene before the user falls asleep at night, a relaxing video, such as a natural scene video, needs to be recommended to the user.
When recommending the corresponding media file for the user, the media file recommending apparatus may also recommend the media file for the user based on the media file playing amounts of all the users. However, the pushed media file is content that is of interest to most users, but perhaps the user is not interested in the media file.

FIG. 2 is an exemplary flowchart of a media file recommendation method according to an embodiment of the present invention. The method may be applied to a media file recommendation device in an implementation environment as shown in FIG. 1, and as shown in FIG. 2, the method may include the steps of:
step 201: receiving a media file recommendation request from an application client, wherein the media file recommendation request comprises a user identification.
In one embodiment, when a user operates an application client on a terminal device (for example, the application client is started and a media file list displayed by the application client is refreshed), a media file recommendation operation is triggered, and the application client sends a media file recommendation request to a media file recommendation device.
In one embodiment, the media file recommendation device may receive the media information recommendation request through a media file recommendation interface 131 as shown in fig. 1, and the media file recommendation interface 131 is located at an access layer for accessing the media file recommendation request. The media file recommendation interface 131 validates the recommendation request. Specifically, the media file recommendation interface 131 parses the media file recommendation request to obtain a user identifier, where the user identifier includes an application identifier (APP ID), an identity authentication code (UIN code), and a password. The media file recommendation interface 131 sends the parsed user identification to the authentication server. The authentication server performs authentication based on the user identification and returns the authentication result to the media file recommendation interface 131. If the verification result is that the identity is valid, the media file recommendation interface 131 forwards the media file recommendation request to the media file recommendation module 133.
Step 202: and responding to the media file recommendation request, and acquiring user state information corresponding to the user identification.
In one embodiment, the media file recommendation module 133 obtains the media file recommendation request, parses the included user identifier, and obtains the user status information corresponding to the user identifier from the user status information server. The user state information is determined based on current user state parameters reported by the wearable device, and the current user state parameters reported by the wearable device include user physiological parameters, such as exercise data of the user, such as step frequency and pace, health indexes of pulse and heart rate, and information of sleep state. User state information, such as a strenuous exercise end state, an emotional asymptotic state, a calm state, a fatigue state, etc., may be determined by the user state parameters.
Step 203: and selecting a corresponding media file according to the user state information.
In one embodiment, each user state corresponds to at least one media file tag, e.g., a fatigue state corresponds to tag relaxation, light music, and a strenuous exercise state corresponds to tag rock, gunfight. Correspondingly, each media file has at least one tag. And the media file recommending device determines the media file labels corresponding to the user state information and acquires a preset number of media files corresponding to the media file labels. For example, if the current user state information is a fatigue state, the media file tag corresponding to the obtained user state information is a slow music or a light music. Media files corresponding to media file tags soothing, light music are selected.
In one embodiment, media files having all of the at least one media file tags corresponding to the user status information may be selected. For example, when a corresponding media file is selected, media files having both a comfort and a light music tag are determined. If the media files having all of the at least one media file tag corresponding to the user status information are less than the predetermined number of media files, selecting the media file having at least one of the at least one media file tag corresponding to the user status information. Still taking the user status information as the fatigue status as an example, if the number of media files having two tags of comfort and light music is less than the preset number of recommended files, the media file having the comfort tag and the media file having the light music tag are respectively selected. If the media files having all at least one media file tag corresponding to the user status information are larger than the predetermined number of media files, the corresponding media file can be selected according to the information such as the play history record or the play amount of the media file corresponding to the user.
In one embodiment, the media file recommender may also obtain user context information from the user status information database 170, which is determined based on current and historical user status parameters reported by the wearable device, for example, lunch break. And selecting a corresponding media file according to the user state information and the user scene information. Specifically, the media file recommending device determines a first media file label corresponding to the user state information and determines a second media file label corresponding to the user state information; and acquiring media files with preset number corresponding to the first media file label and the second media label. For example, the acquired user state information is in a calm state, and the corresponding first media file label is a release; the acquired scene information is noon break, and the corresponding second media file label is love. In this way, media files having both relaxing and love tags are selected.
Step 204: and sending the link of the media file to the application client.
Thus, the application client side obtains the media file according to the link of the media file and displays the media file.
Fig. 3 is an exemplary flowchart of a method for managing user status information according to an embodiment of the present invention. The method is applied in an implementation environment as shown in fig. 1. As shown in fig. 3, the method may include the steps of:
step 301: the wearable device 110 reports the user status parameters to the user status parameter management server 120.
In one embodiment, the wearable device 110 may report the user status parameter periodically. The wearable device 110 may directly report the user status parameter to the user status parameter management server. The wearable device 110 may also send the user status parameter to a relay device (e.g., a terminal device), and then the relay device forwards the user status parameter to the user status parameter management server 120.
Step 302: the user status parameter management server 120 receives the user status parameters from the wearable device 110 and performs preprocessing operations.
In one embodiment, the user status parameter database 150 may store the current user status parameter and the historical user status parameter reported by the wearable device 110, where the historical user status parameter may be the user status parameter reported by the wearable device within a preset period of time (e.g., one month, three months, or half a year).
In one embodiment, in the user status parameter management server 120, the data reporting interface 121 receives the user status parameters from the wearable device 110. The current user state parameters include, but are not limited to, user physiological parameters, such as exercise data of the user, such as step frequency and pace, health indexes of pulse and heart rate, and information of sleep state.
Specifically, the data reporting interface 121 receives data reported by the wearable device 110, requests the reporting module 122 to report the user status parameter, and reports the user status parameter to the parameter reporting module 122. After receiving the request of the data reporting interface, the parameter reporting module 122 receives the reported user status parameter, and performs data preprocessing operations on the user status parameter, such as validity check and data sorting. Step 303: the user status parameter management server 120 stores the currently received user status parameters to the user status parameter database 150.
Step 304: the parameter analysis server 160 retrieves updated user status parameters from the user status parameter database 150.
In one embodiment, the parameter analysis server 160 may periodically obtain updated user status parameters from the user status parameter database 150, where the updated user status parameters are the user status parameters newly stored in the user status parameter database 150 in the current period.
Step 305: the parameter analysis server 160 analyzes the user status parameters to obtain corresponding user status information.
In one embodiment, the parameter analysis server 160 analyzes, models, and analyzes the current status parameters of the user to derive the user status information. For example, if the user's current state parameters are heart rate averaging 75 breaths per minute and breath count 16-20 breaths per minute, the user state may be inferred to be a calm state.
In one embodiment, the parameter analysis server 160 may further derive corresponding context information according to the user's current state parameters and the user's historical state parameters. For example, the current status parameters of the user are heart rate of 75 times per minute and respiration of 16-20 times per minute. According to the user historical state parameters, the user can be inferred to have a nap in the next time period through behavior modeling. Thus, it can be inferred that the user is in a scene before afternoon nap and in a calm state.
Step 306: the parameter analysis server 160 stores the user status information to the user status information database 170.
In one embodiment, the parameter analysis server 160 may also store the obtained user context information to the user status information database 170.
