Problems solved by technology

[0005] Regardless of which of the above methods of constructing user portraits, it is necessary to wait for a certain period of time before constructing user portraits, so the timeliness is poor, and the accuracy of recommending data information to users based on the constructed user portraits is not high; in addition , because the user portrait is constructed after waiting for a certain period of time, so the log information needs to be processed in batches when constructing the user portrait, resulting in long processing time, complex process and large amount of calculation

Embodiment 1

[0092] An embodiment of the present invention provides a method for constructing a real-time portrait of a user. The method for constructing a real-time portrait of a user provided by the embodiment of the present invention will now be explained in combination with the above content. see image 3 , the method flow provided by this embodiment includes:

[0093] 301. Obtain log information of a user.

[0094] 302. Filter the log information to obtain key fields of the log information, wherein the key fields include at least a user ID, a generation time of the log information, a data source ID of the log information, and a product ID.

[0095] 303. Extract the label identifier of the key field.

[0096] Further, extract the label identification of key fields, including but not limited to:

[0097] Detect whether the key field contains the behavior category identifier;

[0098]If the key field contains the behavior category identifier, the behavior category identifier is used ...

Embodiment 2

[0126] The embodiment of the present invention provides a method for constructing a real-time portrait of a user. Combining the above-mentioned introduction to the Storm streaming computing platform and the first embodiment above, the method for constructing a real-time portrait of a user provided by the present invention will be explained in detail. see Figure 4 , the method flow provided by the embodiment of the present invention includes:

[0127] 401. Obtain log information of the user.

[0128] In order to ensure that the user's log information can be obtained, before obtaining the user's log information, the data subscription of each data source is also required. That is, only after subscribing to the data of a certain data source, can the user's log data be obtained from the certain data source, and then the user's log data can be analyzed to obtain the user's log information.

[0129] Optionally, after the user's log information is obtained, the obtained user's log ...

Embodiment 3

[0189] An embodiment of the present invention provides a device for constructing a real-time portrait of a user, which is used to execute the method provided in the first or second embodiment above, see Figure 6 , the device consists of:

[0190] The log information obtaining module 601 is used to obtain the log information of the user; the log information obtaining module 601 is connected with the filtering module 602; the filtering module 602 is used to filter the log information obtained by the log information obtaining module 601, and obtain the key of the log information Field; filtering module 602 is connected with extraction module 603; extraction module 603 is used to extract the label identification of the key field obtained by filtering module 602; extraction module 603 is connected with current label information acquisition module 604; current label information acquisition module 604 , used to obtain the current tag information according to the tag ID extracted by ...

Abstract

The invention discloses a method and a device for constructing a real-time portrayal of a user and belongs to the technical field of data processing. The method comprises the following steps: acquiring log information of the user; filtering the log information to obtain a key field of the log information; extracting a label identification of the key field; according to the label identification and the key field, acquiring current label information; according to the label identification, determining all interest categories corresponding to the current label information; according to the current label information, acquiring user interestingness corresponding to each interest category. According to the invention, after the log information is filtered to obtain the key field, the label identification of the key field is extracted and according to the label identification and the key field, the current label information is acquired so as to acquire the user interestingness corresponding to each interest category after the interest categories corresponding the current label information are determined; the method and the device implement that after one piece of log information of the user is acquired, the real-time portrayal of the user is constructed again, so that data information can be recommended to the user according to the real-time portrayal of the user.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for constructing a real-time portrait of a user. Background technique [0002] With the rapid development of network technology, the Internet has become a platform for users to share information. Therefore, the Internet is full of massive data information. In this case, users are often lost in the low-value mass data information. Therefore, how to recommend the data information that the user is interested in to the user has become a technical problem. One of the key technologies used when recommending data information to users is to establish user portraits. The so-called user portraits are user behavior attributes (such as browsing and purchasing behavior records) and basic attributes (such as gender, age, etc.) Aggregate analysis (such as analyzing users' interest in different product categories), model users, and recommend data information for use...
