目前国内慢性病患者为2.1亿人,占全国人口的15.7%,其中45岁以上人群平均每5个人中有2个人患有慢性病.尽管存在大量信息说明饮食与疾病间的作用,但是这些信息分散、不系统,并且存在矛盾的情况.该文面向互联网数据,生成符合医学与食品领域知识的关系图,并应用Gephi对食品与疾病的关系图进行可视化设计.由于gexf文件数据量大,故提出按需获取子图算法.最后在安卓手机上实现健康饮食顾问,为民众提供便携式健康饮食顾问服务.

The relationship graph can be constructed by extracting the most robust and reliable semantic relationships among foods and health conditions.

Furthermore, the approach of sub graph on-demand can empowers users to naturally and effectively explore, adventure and discover knowledge in a rich food/health relationship graphs in a personalized fash- ion.
