Embodiment Construction

[0029] Such as figure 1 As shown, the user portrait knowledge similarity calculation method of the present invention includes the following steps:

[0030] Step 1: Count the standard behaviors and basic attributes that affect user portraits. Standard behaviors include viewing, liking, sharing, collecting, downloading, commenting, and asking questions. The basic attributes include departments, positions, roles, and majors; the present invention selects users There are 5 standard behaviors (behavior operations) of downloading, asking questions, collecting, sharing, and commenting, and two basic user attributes of department and position, with a total of 7 parameters.

[0031] Step 2: Assign weights to standard behaviors and basic attributes, and set the weight of each parameter , and recorded as , the present invention has 7 calculation values ​​in total, taking .

[0032] Step 3: Extract standard behavior records and basic attribute tags, record the user behavior log tab...

Abstract

The invention discloses a user portrait knowledge similarity calculation method, and belongs to the technical field of intelligent analysis, and the method comprises the steps: firstly stipulating theimportant behaviors of a user, the selection number of personal basic attributes, and the specific behavior operation and attribute contents; secondly, performing parameter weighting on each user behavior and each user attribute, and determining a specific gravity value of the user behavior and the user attribute in overall knowledge similarity calculation; extracting behavior records and attributes of the user, counting labels associated with knowledge accessed by user behaviors, and endowing the labels with weight one by one; and finally, collecting the total weight values of the user knowledge labels, and performing sorting according to the weights to obtain a user knowledge portrait. The knowledge similarity is calculated based on the user behavior operation and the parameter weight of the personal basic attribute, the user portrait is drawn through the specific behavior operation of the user, and the matched similar knowledge is correspondingly returned. The method is high in knowledge recommendation accuracy, the recommendation proportion can be dynamically adjusted, and operation is convenient.

Description

technical field [0001] The invention relates to a method for calculating the similarity degree of user portrait knowledge, which belongs to the technical field of intelligent analysis. Background technique [0002] Today is an era of massive data, and users can receive a lot of information on various websites. A large part of this is invalid, repetitive, or spam traffic that users are not interested in. When users query knowledge, they need to spend a lot of time and energy traversing the search results, or salvaging in the vast knowledge base. In order to accurately deliver similar knowledge to users that conforms to user behavior habits and personal characteristics, a method that can dynamically adjust the weight ratio and perform statistics based on the tags of a single piece of knowledge is needed to obtain user knowledge portraits and personal knowledge tags for dynamic knowledge similarity recommendations . Contents of the invention [0003] In order to solve the ...
