我们开发了T 奥龙托 O 笔 D ATA S earch 支持 特设 、交互式发现连接或 联系 数据集之间。它可以用来有效地浏览开放数据云。我们的系统由三个部分组成:一个Web应用程序提供的用户界面;一个可扩展的后端基础设施,支持导航查询;和一个开放的数据表的动态存储库。我们的系统使用LSH Entrance,一种高效的索引结构,在互联网规模上真实的时间内计算链接(两个数据集中具有高包含分数的属性)。我们的应用程序允许用户通过连接数据集来沿着这些链接导航。 LSH Ensemble是可扩展的,即使在数百万个数据集上也能为链接发现查询提供毫秒级的响应时间。我们的系统为用户提供了一个高度互动的体验,使不相关(和未链接)的动态数据集集合显示为一个丰富的连接的数据云,可以在真实的时间轻松导航和组合。
We developed T oronto O pen D ata S earch to support the ad hoc , interactive discovery of connections or linkages between datasets. It can be used to efficiently navigate through the open data cloud. Our system consists of three parts: a user-interface provided by a Web application; a scalable backend infrastructure that supports navigational queries; and a dynamic repository of open data tables. Our system uses LSH Ensemble, an efficient index structure, to compute linkages (attributes in two datasets with high containment score) in real time at Internet scale. Our application allows users to navigate along these linkages by joining datasets. LSH Ensemble is scalable, providing millisecond response times for linkage discovery queries even over millions of datasets. Our system offers users a highly interactive experience making unrelated (and unlinked) dynamic collections of datasets appear as a richly connected cloud of data that can be navigated and combined easily in real time.
