Abstract

The present invention provides a method and system for determining information similarity. Based on the time when information is consumed, the information consumed by each user is sorted to obtain the corresponding first information behavior sequence; the first information behavior sequence corresponding to all users is The sequence is integrated to obtain the second information behavior sequence; calculate the first similarity between each pair of information with a co-occurrence relationship in the second information behavior sequence; based on the second information behavior sequence, construct a topological map between information; use The graph convolution algorithm calculates the second similarity between each pair of nodes in the topological graph; based on the first similarity between each pair of information with a co-occurrence relationship, combined with the second similarity between each pair of nodes in the topological graph The second similarity is to determine the final similarity between each pair of information in the second information behavior sequence. Combine the two methods to calculate the final similarity between information, increase the amount of information covered by the method of calculating similarity, and then improve the accuracy of information recommendation.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for determining information similarity. Background technique [0002] In the field of information recommendation, the more commonly used information recommendation algorithm is collaborative filtering algorithm. When using collaborative filtering algorithm for information recommendation, it is necessary to calculate the similarity between information. [0003] At present, the collaborative filtering algorithm calculates the similarity between information by calculating the similarity between information according to the co-occurrence times of the information. However, in practical applications, users will generate a large number of sparse behaviors, and the co-occurrence relationship between information is too small, which will lead to a small amount of information that can be covered by the collaborative filtering algorithm, which will lead to a low ...
