rdf:SynopsViz -层次关联数据可视化探索与分析框架

rdf:SynopsViz - A Framework for Hierarchical Linked Data Visual Exploration and Analysis

Nikos Bikakis, Melina Skourla, George Papastefanatos

摘要:

数据可视化的目的是为信息感知和操作提供直观的方式,特别是对于非专家用户。Web of Data已经实现了大量数据集的可用性。然而,可用信息的数量和异质性使得人类难以手动探索和分析大型数据集。在本文中,我们提出了rdf:SynopsViz,分层图表和可视化探索的链接开放数据(LOD)的工具。分层LOD探索基于基于一个或多个属性的值创建多个级别的分层相关资源组。所采用的层次模型提供了有效的信息抽象和概括。此外,它还允许高效的动态统计计算,使用层次结构级别上的聚合。

英文摘要:

The purpose of data visualization is to offer intuitive ways for information perception and manipulation, especially for non-expert users. The Web of Data has realized the availability of a huge amount of datasets. However, the volume and heterogeneity of available information make it difficult for humans to manually explore and analyse large datasets. In this paper, we present rdf:SynopsViz, a tool for hierarchical charting and visual exploration of Linked Open Data (LOD). Hierarchical LOD exploration is based on the creation of multiple levels of hierarchically related groups of resources based on the values of one or more properties. The adopted hierarchical model provides effective information abstraction and summarization. Also, it allows efficient -on the fly- statistic computations, using aggregations over the hierarchy levels.
