DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the embodiments of the present invention more comprehensible, the following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
FIG. 1 is a schematic flowchart of Embodiment 1 of a method for generating a terminal log according to the present invention. As shown in FIG. 1, the method includes the following:
S10. Obtain sensor information and/or user use information of a mobile terminal.
The sensor information may include any one type of the following information or a combination of multiple types of the following information: acceleration information of the terminal, location information of the terminal, and direction information of the terminal, but is not limited thereto. It should be noted that the sensor information may be obtained by the mobile terminal by using various sensors configured thereon, such as a Global Positioning System (GPS) sensor and an acceleration sensor. In a specific implementation process, each type of information described above is recorded in a specific format. For example, location information at a time point obtained in the GPS sensor may be represented as {time, longitude, latitude, altitude}. Acceleration information at a time point obtained in the acceleration sensor may be represented as {time, x-axis acceleration, y-axis acceleration, z-axis acceleration}.
The user use information may include any one type of the following information or a combination of multiple types of the following information: user call record information, user short message record information, network connection information of the terminal, and system process information of the terminal, but is not limited thereto. The obtained user call record information may include call start time, call end time, call duration, calling number, called number, and the like. The obtained short message record information may include short message receiving time, length of a received short message, short message sending time, length of a sent short message, and the like. The obtained network connection information may include a connection situation where the mobile terminal is connected to a wireless access point or a base station by using a Wireless Fidelity (Wi-Fi) network or a third generation (3G) communication technology network, and may specifically be an ID, a name, signal strength of a Wi-Fi node or 3G node, and the like. The system process information may include a process that the mobile terminal is running and resource usage of the process, such as a central processing unit (CPU) and a memory. The mobile terminal here performs recording according to a specific operation of a user and by using a specified format. For example, each piece of user call record information may be represented as {time, local mobile phone state, peer mobile phone state, local mobile phone setting state, peer mobile phone ID}. A more specific piece of call record information may be {time, call received, calling, mobile phone ringing, peer mobile phone ID}.
S20. Generate first log information according to the sensor information and/or the user use information.
The terminal may obtain an activity or an event of the user by performing analysis using a set analysis policy according to the sensor information and/or the user use information. The analysis policy here may be pattern recognition, machine learning, rule setting, and the like, but is not limited thereto. Taking an acceleration sensor as an example, the terminal obtains acceleration sensor information {time 1, x1, y1, z1}, {time 2, x2, y2, z2}, {time 3, x3, y3, z3}, . . . by using the acceleration sensor; and uses a specific algorithm to recognize {start time 1, end time 1: action 1, action 2}, {start time 2, end time 2: action 1, action 2}, {start time 3, end time 3: action 1, action 2}, . . . that is, the acceleration sensor information is recognized, depending on the magnitude of acceleration within a period of time, as a specific action such as walking, running, jumping, and the like. Finally, according to a predefined rule, a result that “xxx is running between 9:00 to 9:15 in the morning” may be obtained. It should be noted that a speed range may be set in the predefined rule. For example, when the moving acceleration of a user is between x m/s²and y m/s², it may be deemed that the user is running; however, the present invention is not limited thereto.
Furthermore, the terminal may also generate, according to the activity and/or the event of the user obtained by performing analysis and by using a set generation policy, the first log information for describing the activity and/or the event of the user. A rule may be predefined in the generation policy according to the requirements of the user, thereby combining and filtering the obtained activity and/or event information. For example, in the process mentioned above, information “the user keeps walking between 8:00 and 9:00 in the morning” may be obtained. Such information having no actual meaning may be deleted when a log is generated. Moreover, analysis is performed according to time information. The information within the same period of time is combined according to the comprehensiveness of the sensor information and the user use information. For example, according to the comprehensiveness of the information obtained from the acceleration sensor and the user call information, it is determined that “xxx1 talks with xxx2 between 9:00 and 9:30, and xxx1 is exercising intensely, and may probably be running according to the acceleration sensor”.
S30. Receive second log information input by a user.
Specifically, the user may write a log on the mobile terminal, which may include a text, an image, and the like.
S40. Combine the first log information with the second log information to generate terminal log information.
That is, the log automatically generated by the mobile terminal and the log written by the user are combined after correlation analysis, where the terminal log information may be generated according to a time sequence and/or content correlation of content recorded by the first log information and the second log information.
For example, first log information generated automatically by the terminal is “the mobile phone is muted between 9:00 and 9:50 on Sep. 1, 2012. xxx calls at 9:40 with no answer”. Second log information written by the user is “participate in a weekly routine meeting between 9:00 and 10:00 today”. After a combination, the obtained terminal log information is “participate in the weekly routine meeting between 9:00 and 10:00 today, and the mobile phone is muted between 9:00 and 9:50. xxx calls at 9:40 with no answer”.
It should be noted that the log information generated by the mobile terminal is generally a state or an action of the user at a time point, and the log written by the user generally records content within a period of time. In a combination process, a priority may be set so that the log written by the user is prior in the automatic combination process.
In the embodiment, the mobile terminal, by obtaining related sensor information and/or user use information and combining a log generated by the terminal with a log written by a user, ensures that an activity or event of the user is accurately obtained.
In addition, the terminal may also, after generating the first log information according to the sensor information and/or the user use information, update the first log information according to a received modification input by the user.
In a specific implementation process, the mobile terminal may display the generated first log information to the user, and the user may edit and modify the first log information according to a specific situation, to generate the updated first log information. The log may be classified, for example, be classified into a sport log and a health log, for the user to view conveniently.
In addition, after the first log information is updated according to the modification information, the modification information is compared with the first log information before the updating.
The set analysis policy is adjusted according to a result of the comparing, and/or the generation policy is adjusted according to a result of the comparing.
For example, first log information generated by the mobile terminal is “walking from 9:00 to 10:00 in the morning”, and the user modifies it to “jogging from 9:00 to 9:30 in the morning, and walking from 9:30 to 10:00”. The reason may be that a speed range set for walking may be too large. Then, the mobile terminal may adjust, according to the modified log information, the speed range for determining that the user is walking, which is set in the analysis policy.
It should be noted that when the first log information and the second log information are combined, the first log information that is updated and modified by the user may be used.
FIG. 2 is a schematic flowchart of Embodiment 2 of a method for generating a terminal log according to the present invention. As shown in FIG. 2, according to the description of the foregoing embodiment, the whole process of the method is as follows:
S201. Obtain sensor information and/or user use information of a mobile terminal.
S202. Analyze the obtained information by using an analysis policy to obtain an activity and/or an event of a user.
S203. Automatically generate a log by using a generation policy. According to the result of the above analysis, generate the log automatically.
S204. Display the automatically generated log to the user and receive a modification made by the user.
S205. Compare the log modified by the user with the log before the modification.
S206. Feed back a result of the comparing, and correspondingly modify and update the analysis policy and the generation policy automatically.
S207. Combine the modified log with a log written by the user to obtain a final terminal log.
It should be noted that the execution process described above is not fixed, where if the user does not modify the automatically generated log, no comparison is required; and if the user does not write a log, no combination processing is required, and the final terminal log may be directly obtained.
In the embodiment, the mobile terminal may automatically generate a log by obtaining related sensor information and user use information, accept the editing and modification made by the user, and combine the log with a log written by the user, which not only reduces the time for the user to write a log, but also achieves accurate obtaining of an activity or event of the user. In addition, by comparing the information before and after the user makes the modification, the set analysis policy and generation policy are automatically adjusted, which can continuously improve the accuracy of obtaining the activity or the event of the user.
