在调研中国主要的11类网络农产品价格信息源的基础上,构建了描述农产品价格信息属性的九元组,并采用聚类分析法划分了3类语义异构类型:模式语义异构、上下文数据语义异构、个体异常数据语义异构。最后,分析了消除多源网络农产品价格信息语义异构的现有方法和不足,并明确了进一步研究的方向。
On the basis of investigating the information sources of price of agricultural products in 11 major types in China, this paper constructs a 9-tuple describing the attributes of agricultural products price information, and uses the cluster analysis method to classify 3 types of semantic heterogeneity: schema semantic heterogeneity, contextual data Semantic heterogeneity, individual anomaly data semantic heterogeneity Finally, the existing methods and deficiencies of semantic heterogeneity of agricultural products price information in multi-source networks are analyzed and the direction of further research is clarified.
