摘　　要：目的 针对饮食不均衡和搭配失当而造成的饮食问题给人们身心健康带来不良影响,尤其是饮食对慢性病研究的发展等问题,为了设计和开发一个能够根据用户个人状况、喜好、口味等因素,提出向用户推荐符合其身体需求的营养膳食的智能系统。方法 搭建了一个基于人工智能知识库的营养膳食推荐系统,利用专家验证的膳食的明确数据集,结合基于推理决策支持系统(RDSS)和营养计划(NP)运用NAct本体论提供高度准确的饮食计划,跨越10个用户组,包括健康的受试者和有健康状况的参与者。结果 该系统的有效性通过广泛的实验进行评估,评估涉及合成数据,包括生成3 000个虚拟用户档案和他们的每周膳食计划。结果显示,在大多数用户类别中,推荐适当成分的精确度和召回率都很高,而膳食计划生成器对所有营养素的推荐达到了94%的总推荐精确度。结论 基于人工智能知识库的营养膳食推荐系统可以根据用户的身体状况、喜好、饮食禁忌等方面进行个性化推荐。这样的个性化推荐能够更好地满足用户的需求,从而提高推荐的准确度。专家知识库包含了广泛的营养学和健康知识,这些知识可以帮助系统识别出最适合用户的膳食方案。这些方案不仅可以提供充足的营养,还可以避免与用户的健康状况不兼容的食物或成分。Objective Addressing the adverse effects of dietary problems caused by imbalanced nutrition and poor food combinations on people’s physical and mental well-being,particularly concerning research on the relationship between diet and chronic diseases,an intelligent system capable of recommending sound and nutritionally balanced meals tailored to users’conditions,preferences,and tastes was designed and developed.Methods A nutrition meal recommendation system based on an artificial intelligence knowledge base was constructed.It utilized a definitive dataset of diets validated by experts,combined with a reasoning decision support system(RDSS)and a nutritional plan(NP),employing NAct ontology to provide highly accurate dietary plans.It spanned 10 user groups,including healthy subjects and participants with health problems.Results The effectiveness of the system was assessed through extensive experiments,which involved synthetic data including the generation of 3,000 virtual user profiles and their weekly dietary plans.The results indicated high precision and recall rates for recommending appropriate ingredients across most user categories,with the dietary plan generator achieving an overall recommendation accuracy of 94%for all nutrients.Conclusion The nutrition meal recommendation system based on an artificial intelligence knowledge base can personalize recommendations based on users’physical conditions,preferences,dietary restrictions,and other aspects.Such personalized recommendations can better meet users’needs,thereby enhancing the accuracy of the recommendations.The expert knowledge base encompasses extensive nutrition and health knowledge,which can assist the system in identifying the most suitable dietary plans for users.These plans not only provide ample nutrition but also avoid foods or ingredients incompatible with users’health conditions.
