In this embodiment, a method for generating a behavior sequence is provided, and fig. 2 is a flowchart of the method for generating a behavior sequence according to the embodiment of the present invention, where the flowchart includes the following steps:
step S202, acquiring data records of a target object to different devices, wherein the data records comprise: the target object is used for operating events of different devices and action execution time corresponding to the operating events;
for example, different target objects have different behavior characteristics, and before processing the data records, the data records of different devices corresponding to different target objects can be distinguished through object identifiers existing in the original data.
Step S204, determining the action execution sequence of the operation events according to the sequence of the action execution times of the operation events;
that is to say, in order to facilitate the processing of the subsequent behavior sequence, after the data records of any one target object for different devices are obtained, the plurality of operation events are time-sequenced according to the action execution time corresponding to the operation event carried in the data records, and the action execution sequence executed by the target object for each operation event is determined.
Step S206, determining a time interval between every two adjacent operation events according to the action execution sequence, and determining a behavior sequence of the target object according to the time interval, where the behavior sequence is used to indicate a plurality of operation events that are continuously executed by the target object within a preset time period.
Through the steps, data records of the target object to different devices are obtained, wherein the data records comprise: the target object is used for operating events of different devices and action execution time corresponding to the operating events; determining the action execution sequence of the plurality of operation events according to the sequence of the action execution times of the plurality of operation events; determining the time interval of every two adjacent operation events according to the action execution sequence, and determining the behavior sequence of the target object according to the time interval, wherein the behavior sequence is used for indicating a plurality of operation events continuously executed by the target object within a preset time period, that is, by extracting the behavior sequence corresponding to the data record of the target object to different devices, and further realizing the processing and mining of the original data under the condition of no special data requirement, therefore, the problems that the behavior sequence mining with any length cannot be carried out in the original data in the prior art so as to determine the operation behavior of the target object to different devices and the like can be solved, and further the behavior sequence belonging to the target object can be generated according to the data record of the target object to different devices, and the behavior habit of the target object can be better predicted by using a knowledge graph algorithm based on the behavior sequence, therefore, the operation experience of the target object on the intelligent equipment can be improved, and the first step from the original data to various machine learning algorithms and artificial intelligence algorithms becomes more convenient, efficient and accurate.
For example, the above processing procedure for data recording includes the following steps: acquiring original data records of different devices from an intelligent home system; analyzing the original data record, and extracting the actual action (namely, the operation event) of different objects using different equipment and the action occurrence time of the operation instruction corresponding to the operation event sent by different objects executed by different equipment, wherein the actual action is existed in the original data record; and determining action time sequences among different actions according to the actual action and the action occurrence time, and further determining time intervals among adjacent actions so as to calculate behavior sequence data corresponding to different target objects in the intelligent home system.
In one exemplary embodiment, determining a sequence of behaviors of a target object according to a time interval includes: acquiring the time interval of every two adjacent operation events to obtain a plurality of time intervals; for each time interval in the multiple time intervals, determining the size relationship between each time interval and a preset interval threshold, and determining a first tag value of a first characteristic tag and a second tag value of a second characteristic tag of an operation event according to the size relationship; and determining the behavior sequence of the target object according to the first label value and the second label value.
In brief, in order to ensure the continuous relationship between different operation events, therefore, it is necessary to determine a time interval between every two adjacent operation events, to determine whether there is continuity between every two adjacent operation events by combining a preset interval threshold, and determine a first tag value of a first feature tag and a second tag value of a second feature tag corresponding to an operation event according to a size relationship between each time interval and the preset interval threshold, and further determine a behavior sequence of a target object by using the first tag value and the second tag value as attribute features of the target object.
In one exemplary embodiment, determining a first tag value that is a feature tag of an operational event according to a magnitude relationship includes: under the condition that each time interval is larger than a preset interval threshold, determining that a first label value of a feature label of an operation event with a later action execution time in each two adjacent operation events is an invalid value; and under the condition that each time interval is smaller than or equal to a preset interval threshold, determining that the first label value of the feature label of the operation event with the action execution time after in each two adjacent operation events is a valid value.
For example, if the interval between two actions exceeds 5 minutes, it is considered that the actions are not continuous, and when each time interval is less than or equal to 5 minutes, it indicates that the action corresponding to the operation event is in the middle of one action sequence and the first tag value of the feature tag is recorded as a valid value (e.g., 1), and if the interval is greater than 5 minutes, it indicates that two operation events are not continuous, the first tag value of the feature tag is recorded as an invalid value (e.g., 0).
In one exemplary embodiment, determining a second tag value that is a second feature tag of the operational event according to the magnitude relationship includes: under the condition that each time interval is larger than a preset interval threshold, determining that a second label value of a feature label of an operation event with a previous action execution time in each two adjacent operation events is an invalid value; and under the condition that each time interval is smaller than or equal to a preset interval threshold, determining that the second label value of the characteristic label of the operation event with the action execution time before in each two adjacent operation events is a valid value.
It should be noted that the second index value is a feature tag value corresponding to an operation event subsequent to the operation event and an operation event previous to the operation event, which is calculated on the basis of determining the first tag value.
In one exemplary embodiment, determining the behavior sequence of the target object according to the first tag value and the second tag value includes: combining the first tag value and the second tag value corresponding to each operation event to obtain a data item of the operation event; determining the execution sequence of each operation event in the behavior sequence according to the arrangement sequence of the first tag value and the second tag value in the data item, and identifying each operation event; and determining the behavior sequence of the target object according to the identification result.
In an exemplary embodiment, determining an execution order of each operation event in the action sequence according to an arrangement order of the first tag value and the second tag value in the data item, and identifying each operation event includes: under the condition that the data items are arranged by an invalid value and an effective value, marking a start identifier on the current operation event, and determining the current operation event as a start action behavior; under the condition that the data items are the effective values and the effective value arrangement, marking a current operation event with an identification, and determining the current operation event as an action-in-progress behavior; and under the condition that the data items are arranged by the effective values and the invalid values, marking an ending mark on the current operation event, and determining that the current operation event is an action ending behavior.
In one exemplary embodiment, determining the behavior sequence of the target object according to the identified result includes: recording the identification result of each operation event by using a target field; matching the identification result with the data records of different equipment obtained by the target object; and extracting the identification result and the action execution time corresponding to the operation event by using a preset data structure to obtain a behavior sequence corresponding to the operation event sequence for representing that the target object executes different devices.
In order to better understand the process of the method for generating the behavior sequence, the following describes a flow of the method for generating the behavior sequence with reference to two alternative embodiments.
In the optional embodiment of the invention, a method for calculating any length of behavior sequence of the intelligent household user is mainly provided, wherein each complete action sequence of the user is mined from mass data, then the user habit can be processed by using an algorithm, and the complete habit of the user is formed by cold start recommendation of all users, so that a foundation is provided for other algorithms and applications.
As an optional implementation manner, in the smart home internet of things recommendation system, a recommendation algorithm is performed, and it is implemented that a user action sequence is found, but the smart home system is different from a common shopping system and does not have the concept of session (session management or session control). The general shopping system generally uses the concept of session (implemented with multiple language frameworks and manners), records all actions of a user in a session, and performs related user behavior intention recognition according to the actions.
Optionally, a common data structure (equivalent to a data record in the embodiment of the present invention) of the internet of things gateway is as shown in table 1 below: the table records the original data of the smart home user, and records the time, the corresponding action and other attributes of different users operating different devices at different times. In the table, the header is a user ID, a device ID, an action occurrence time, and an action ID, and the last columns are other attributes.
TABLE 1
Data of User ID Device ID Time of transmission of action Actual transmission time Other Properties
Record
1 USER1 DEVICE1 TIME-STAMP1 ACTION1 OTHERS
Record 2 USER2 DEVICE2 TIME-STAMP2 ACTION1 OTHERS
Record 3 USER3 DEVICE2 TIME-STAMP3 ACTION1 OTHERS
It should be noted that the user ID is the unique number of the user in all users, and may be numbered in various ways, such as a mobile phone number and other encrypted numbers generated by the mobile phone number; the device ID is a unique number in all devices, that is, each device has only one number, and the numbers of the same device but different devices may be different. The action occurrence time is a time occurring when a user uses a certain device and gives a certain instruction to the certain device, and it is noted that the time is not a time when the instruction is recorded but a time when the instruction is executed. If the command issue is not executed, no record is generated. The actually occurring action is an action actually performed when the user uses the device. If multiple actions occur at the same time, multiple records are generated. However, since the computer calculates time in milliseconds, it is substantially unlikely that multiple actions will occur at a time. Other attributes may record multiple attributes, such as user age, gender, how long the device was used, etc., to facilitate the recommendation of algorithms and data mining efforts.
Alternatively, FIG. 3 is a timing diagram of a sequence of data processing determination actions performed by a data structure according to an alternative embodiment of the invention.

It is noted that FIG. 10 is a flow diagram of a sequence of data processing determining actions performed by a data structure in accordance with an alternative embodiment of the present invention; the data result can be processed arbitrarily by the above method to generate a sequence. The method can be used as the input of an artificial intelligence algorithm and a machine learning algorithm, or can directly perform data mining, such as calculating the time of the user lasting the longest action sequence, the action quantity and the like. The data structure may be used as a basis for all user behavior pattern recognition.
In summary, with the alternative embodiment of the present invention, a behavior sequence of any length can be generated. The key point is the construction of a feature vector when a user sequence starts and ends, and the protection point is a calculation method mainly for the feature vector, because if the generation of a complete action sequence algorithm of a user is required to be calculated, the complete action sequence is a basic data structure of data mining, machine learning and an artificial intelligence algorithm.

Therefore, the behavior data corresponding to the original data can be connected with advanced knowledge mapping algorithm and the like.
