源描述框架(Resource Description Framework，RDF）来描述网络数据。本文通过

对新浪微博上较为杂乱的微博数据进行分析，根据 RDF 三元组规则，为其中所需有

用信息数据添加语义，并以 XML 为语法,编写算法将其转换为 RDF 文件；此外，研究

growing big data on the Web,which uses the Resource Description Framework(RDF) to

description the network data.This article through to make an analysis of the messy

Weibo’s data,and to add semantics for the needed and useful data by the rules of RDF

triples, then, write algorithms to convert it to RDF file by the grammar of the XML, in

addition, studied the use of RDF database Virtuoso and import the RDF file of Weibo’s

data into Virtuoso,using SPARQL language for its fast query and validated. All in all, this

article provides reference for the Weibo data semantic conversion, and has great

significance for improvig the retrieval efficiency of the network resources.
