从三重模式片段图中提取基本图模式

Extracting Basic Graph Patterns from Triple Pattern Fragment Logs

Nassopoulos Georges, Serrano-Alvarado Patricia, Molli Pascal, Desmontils Emmanuel

摘要:

Triple Pattern Fragment(TPF)方法实际上是一种以低成本和高服务器可用性发布关联数据的新方法。但是,托管TPF服务器的数据提供程序不能分析它们执行的SPARQL查询,因为它们只接收和评估具有一个三重模式的查询。在本文中,我们提出了LIFT:一个算法来提取基本图形模式(BGP)的执行查询TPF服务器日志。实验结果表明,LIFT算法提取出的BGP具有良好的查准率和查全率,噪声较小。

英文摘要:

The Triple Pattern Fragment (TPF) approach is de-facto a new way to publish Linked Data at low cost and with high server availability. However, data providers hosting TPF servers are not able to analyze the SPARQL queries they execute because they only receive and evaluate queries with one triple pattern. In this paper, we propose LIFT: an algorithm to extract Basic Graph Patterns (BGPs) of executed queries from TPF server logs. Experiments show that LIFT extracts BGPs with good precision and good recall generating limited noise.
