开放数据是通过释放数据来实现资源共享并创造价值,关联数据则是借助数据之间的相关性进行关联以促进资源的共享和重用,并为用户提供丰富的数据链接网。本文对开放数据的相关性进行研究,构建开放数据的相关性四维模型,从数据资源(两维)、时间和RDF三元组四个维度解析数据之间的相关性,并基于不同角度分析相关性价值,对于政府数据开放具有一定的实践意义和应用价值。
Open data is to release the data to achieve the sharing of resources and create value, the associated data is based on the correlation between the data association to promote the sharing and reuse of resources, and provide users with rich data link network. This paper studies the correlation of open data, constructs the correlation four-dimensional model of open data, analyzes the correlation between data from the four dimensions of data resources (two-dimensional), time and RDF triples, and analyzes the correlation based on different angles The value of sex, for the government data has some practical significance and application value.
