Abstract

The application discloses a method and device for sorting score calculation of an object to be evaluated, a method and device for building a sorting score calculation model, and a commodity recommendation system. The method for calculating the sorting score of the object to be evaluated comprises the following steps of acquiring original rating data of the object to be evaluated, a value of a newly-added sorting factor and actual behavior data extracted from historical behavior data of an actual interaction behavior system; figuring out a weight coefficient of the newly-added sorting factor in the sorting score calculation model according to actual sorting distribution obtained from the actual behavior data and the minimum difference, set in advance of the sorting score calculation module, among forecast sorting distributions as an optimization target; and calculating the sorting score of the object to be evaluated by using the sorting score calculation module. With the method provided by the application, the newly-added sorting factor can be rapidly and conveniently introduced, and moreover, the calculated sorting score can be used for objectively and accurately forecasting and sorting status of the object to be evaluated.

Description

technical field [0001] The present application relates to ranking technology, in particular to a method for calculating the ranking score of an object to be evaluated. The present application also provides a device for calculating the ranking score of the object to be evaluated, a method and device for establishing a ranking score calculation model, and a commodity recommendation system. Background technique [0002] With the popularization of the Internet and the development of website technology, more and more users choose to browse, select, or purchase the commodities they need online. In this case, many websites use various forms of recommendation technology to recommend products to users to varying degrees. The more common method is to select a specific sorting factor and calculate the ranking of the recommended products according to a preset sorting algorithm. points, and then select and recommend products according to the ranking score. [0003] The sorting factor u...
