As an example, the above-mentioned historical order information set may be [ [ pineapple shortbread, 1, 40 times, 5 boxes, 30 yuan, 9.8 folds, 20 yuan, 7 days ], [ scon, 1, 12 times, 20 blocks, 8 yuan, 9.6 folds, 3 yuan, 7 days ], [ cheese tart, 2, 50 times, 3 boxes, 45 yuan, 9.8 folds, 30 yuan, 4 days ], [ pineapple shortbread, 1, 32 times, 2 boxes, 40 yuan, 9.8 folds, 20 yuan, 4 days ] ]. The set of recommended degree values may be [1.46, 0.59, 1.39, 0.56 ]. And the recommendation degree values in the recommendation degree value set are reserved with two decimal numbers.
The formula in step 302 is an invention point of the embodiment of the present disclosure, and solves a technical problem mentioned in the background art that "when recommendation degree evaluation is performed on history order information, categories of history orders are not subdivided, and meanwhile, factors influencing the recommendation degree evaluation of the history order information are not comprehensively considered, so that the generated recommendation degree value is not accurate enough, and further, recommended contents are difficult to meet the appeal of a service providing platform and the frequency of performing value-related operations by a user is difficult to increase, which may cause overstock of goods, waste of shelf resources, and excessive consumption of goods fresh-keeping resources. Factors that lead to overstocking of goods, waste of shelf resources, and excessive consumption of goods fresh-keeping resources are often as follows: factors influencing recommendation degree evaluation of historical order information cannot be comprehensively considered, so that the generated recommendation degree value is not accurate enough. If the above factors are solved, the effects of reducing the overstock of goods, improving the use efficiency of shelf resources and reducing the investment of equipment for keeping the goods fresh can be achieved. To achieve this effect, first, the present disclosure introduces an item value transfer value, an item value transfer value ratio, an item value generation value, and an item value transfer number included in the history order information. Thus, the actual profit value corresponding to each historical order information is obtained. In this way, one appeal of the service providing platform is satisfied. Secondly, the average browsing times of the articles are introduced, so that the requirement degree of the target user for the articles is quantified. In addition, the article tag value is introduced, and whether the article corresponding to the historical order information is actively searched by the user or recommended by the system is represented through the article tag value. In practical situations, if the target user purchases the recommended item of the system, it indicates that the recommended item to the user can often meet the consumption habit of the user. If the target user purchases the article obtained through the active retrieval, the article is indicated to be more consistent with the requirement of the user, and the article similar to the article obtained through the active retrieval by the user can be pushed to the user. The accuracy of the recommendation degree value is ensured to a certain extent by fully considering the factors influencing the recommendation degree estimation. Furthermore, the appeal of the service providing platform is met, and the association degree between the recommended content and the target user is improved, so that the frequency of executing value-related operations by the target user is improved, and the overstocked goods, the waste of shelf resources and the equipment investment for keeping the goods fresh are reduced.
