基于本体和物联网的农产品推荐研究

Agricultural Products Recommended Research Based on Ontology and the Internet of Things

针对消费者日益关注的农产品质量安全问题,借助本体技术知识集成与共享的优势,将更详尽的农产品信息呈现给消费者。首先基于农产品目录信息及农业物联网感知信息分别建立农产品上层本体和下层本体,其次根据消费者信息建立消费者兴趣本体,然后将农产品上层本体与消费者兴趣本体进行概念语义相似度计算,实现个性化推荐。农产品上层本体与下层本体实现映射,消费者通过推荐内容深入了解所要购买的农产品。通过本体及物联网的运用,为消费者提供个性化的农产品推荐服务,确保农产品质量安全,保障消费者身体健康。

In view of the problem of agricultural products quality that consumers increasingly focus on, present more detailed information of agricultural products to consumers by taken advantage of the technology of ontology about knowledge integration and sharing. First, build up upper and lower ontology of agricultural products based on the information of its catalog and the awareness information of Internet of things of agriculture respectively; Then, build up consumers interest ontology based on their information; Finally, compute concept semantic similarity of upper ontology of agricultural products and consumers＇ interest ontology to realize the personalized recommendations. The upper ontology of agricultural products mapping the lower one, consumers could know more about agricultural products they would buy through recommend content. Provide consumers with personalized recommendation service and ensure quality safety of agricultural products and safeguard consumers＇ health by used technology of ontology and Intemet of things.
