Embodiment Construction

[0054] figure 1 It is a multi-objective recommendation flow chart of family diet, and now the embodiment of the present invention will be described in detail.

[0055] The family diet recommendation method based on the similarity of multi-objective needs has the following specific steps.

[0056] Step 1. Obtain basic information of family members. Health information includes dietary taboos for diseases, user's dietary needs, dietary preferences, cooking level, income level, and family role.

[0057] Step 2. Determine the type of recipes to be calculated based on the information of family members suffering from diseases. If there are members of the family suffering from diseases, mark the food that is not conducive to the disease. If the disease requires long-term, that is, more than three months, you need to pay attention to diet If the disease is a disease, the recommended recipe is divided into two parts, one part is not suitable for users with the disease, called recipe A;...

Abstract

The invention discloses a family diet recommendation method and device based on demand similarity of multiple targets. The method mainly aims at meeting the health demands of family members and balancing different diet demands of the family members. The method comprises the steps of collecting health information, role information and demand information of all family members; establishing a diet preference model and a family diet demand model according to the information of the family members; and constructing a food recommendation interval time function model, increasing the types of recommended food to enrich the diet structure, and improving the diversity of a recommendation result. In the aspect of recipe recommendation, nutrition information of disease patients and family members is considered, the requirements of the family members in other aspects are also considered, and multi-target recommendation is realized; and in the aspect of the diet structure of the recommended recipe, change of user preferences along with time and the diversity of the recommended recipe are considered, and through a user preference drifting function and a food recommendation interval time function,a certain food loved by the user is prevented from being continuously recommended, and the diet structure is enriched.

Description

technical field [0001] The invention relates to the field of recommendation systems in computer technology, in particular to a family diet recommendation method and equipment based on multi-objective similarity of requirements. Background technique [0002] In the multi-objective recommendation process of family diet, the most important thing is to consider the health of family members and how to balance the different dietary needs of family members. The results obtained by traditional individual-based dietary recommendation methods cannot fully meet the dietary needs of family members. In addition, if there is a diseased member in the family, it is necessary to ensure the dietary taboos of the diseased member in the family and meet the dietary needs of other family members, and the recommendation of recipes will be more complicated. Therefore, it is necessary to comprehensively consider the information of family members, analyze the specific situation of the family, and fo...
