Abstract

The invention provides a similarity determination method and device, a storage medium and a computer device, and the method comprises the steps: generating a first scoring matrix and a second scoringmatrix of a user for an article according to an input user, the article and behavior data of the user for the article; dividing the first scoring matrix and the second scoring matrix into N sub-matrixes respectively, and allocating the N sub-matrixes to N processes respectively; carrying out similarity calculation by the N processes in parallel; after similarity calculation is completed, sub-matrixes of second scoring matrixes in the N processes are sent to the next process of the corresponding process; and respectively updating the sub-matrixes of the second scoring matrix in the N processesinto the received sub-matrixes, and performing similarity calculation again in parallel by the N processes until the sub-matrixes of the first scoring matrix in the N processes and all the sub-matrixes of the second scoring matrix finish similarity calculation. According to the embodiment of the invention, the similarity calculation speed is improved.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular, the present application relates to a similarity determination method, device, storage medium and computer equipment. Background technique [0002] Similarity calculation is the core problem of traditional recommendation algorithms based on collaborative filtering, which recommends content that users are interested in based on similar users / items / features. The similarity generally includes: the similarity between users, the similarity between items, the correlation between users and items, and so on. There are also many ways to calculate the similarity. For example, the similarity is calculated by cosine (cosine), that is, the user's behavior on the item is converted into a two-dimensional scoring matrix of user-item preference, then the row / column of the matrix can be regarded as a sparse vector, and the cosine between sparse vectors To calculate the ...
