Visual Analytics System for LOD Using Sampling-based Structure Estimation
サンプリングに基づく構造推定を用いたLOD視覚的分析支援システム

Yasufumi Takama, Ayaka Yabe, Hiroshi Ishikawa
2017 Transactions of the Japanese society for artificial intelligence  
In order to support the analysis, the proposed system analyzes the structure of LOD written with RDF, and visualizes the result of analysis.  ...  The RDF (Resource Description Framework), which describes data as a set of triples consisting of subject, predicate and object, is commonly used to publish data as LOD.  ...  Recently, it has been widely used to publish various kinds of data such as statistical data, geographical data, and academic data.  ...

Towards Scalable Visual Exploration of Very Large RDF Graphs [article]

Nikos Bikakis, John Liagouris, Maria Krommyda, George Papastefanatos, Timos Sellis
2015 arXiv   pre-print
In this paper, we outline our work on developing a disk-based infrastructure for efficient visualization and graph exploration operations over very large graphs.  ...  Particularly, the graph layout is indexed with a spatial data structure, i.e., an R-tree, and stored in a database.  ...  The wide availability of vast amounts of graphstructured data, RDF in the case of the Data Web, demands for user-friendly methods and tools for data exploration and knowledge uptake.  ...
