Abstract
A method and apparatus is described to push to-be-recommended products onto users' terminals based on similarities in the to-be-recommended products and products in the users' historical records of products. To improve the pushed recommendations various technics are applied, including: using predefined criteria to filter products provided from the users' historical records, applying temporal decay to provide real-time recommendations, removing already obtained products from the to-be-recommended products to be pushed, improving similarity calculations by determining similarity using pairwise variations between products both in and out of the candidates for to-be-recommended products, sorting the to-be-recommended product according to a preset recommendation policy, calculating pairwise variations using multiple types of similarity measures, using weights to determine the to-be-recommended products, and applying a preset recommendation policy based on a given scenario. Accordingly, the embodiments described herein avoid an excessive recommendation phenomenon (e.g., products previously obtained) and provide improved recommendations.
