Abstract
The present disclosure provides a method and device for transmitting recommended product information. In one embodiment, a system retrieves product evaluation records given by one or more users. Each of the product evaluation records includes an identification of the user (user ID), an identification of the product (product ID), and evaluation information. The system uses the user ID and the product ID as a primary key, and then, based on intervals of the primary key, divides the product evaluation records into several subsets of records, and assigns these subsets of records into multiple calculation nodes. The system retrieves such SVD calculation results of the multiple subsets of records from the multiple calculation nodes. The recommended product information is sent to a client terminal based on the SVD calculation results. The present disclosure implements the distribution processing of SVD calculation, reduces the calculation complexity, and saves the calculation time.
