CONSTRUCTION PRACTICE OF CHINESE FOOD LINKED OPEN DATA
摘要
Abstract
Food linked open data is the basis of personalised menu inquiry, nutritional recommendations, disease diet and some other ap-plications.Since there is not a complete Chinese food linked open data yet, we established the first national Chinese food linked open data which offers SPARQL inquiry and general inquiry services.Moreover, it provided the underlying platform for the development of the upper in-telligent application.In light of the situation of lacking structured data, we also improved the traditional term frequency-inverse document fre-quency algorithm, introduced vision-based page segmentation algorithm, and proposed a general food crawler for semi-structured food website, this made the extraction of food data more intelligent, and improved the accuracy up to 22.1%.关键词
