Exploring Large RDF Datasets using a Faceted Search
نویسندگان
چکیده
We propose a facet-based RDF data exploration mechanism that lets the user visualize large RDF datasets by successively refining a query. The novel aspects of our work are: i) the SPARQL query pattern is visualized as a query graph, ii) the successive refinements are visualized in a query refinement graph, and iii) the result triples are visualized as a result RDF graph. The scheme is scalable and it visualizes RDF graphs stored in Oracle Database 12c Spatial and Graph Option with Cytoscape, a graph visualization tool.

SemFacet: Faceted Search over Ontology Enhanced Knowledge Graphs
In this demo we present the SemFacet system for faceted search over ontology enhanced Knowledge Graphs (KGs) stored in RDF. SemFacet allows users to query KGs with relatively complex SPARQL queries via an intuitive Amazon-like interface. SemFacet can compute faceted interfaces over large scale RDF datasets by relying on incremental algorithms and over large ontologies by exploiting ontology pro...
متن کاملFaRBIE: A Faceted Reactive Browsing Interface for Multi RDF Knowledge Graph Exploration
Linked Data brings numerous RDF Knowledge Graphs to the Web, and as a result, the Linking Open Data (LOD) cloud comprises several independent – but linked – graph datasets. Faceted Browsing is a popular type of User Interface (UI) to explore the knowledge in these RDF graphs. Due to the distributed and linked nature of RDF graphs, exploring more than one graph at a time is a common interaction ...
متن کاملFaceted search over RDF-based knowledge graphs
Knowledge graphs such as Yago and Freebase have become a powerful asset for enhancing search, and are being intensively used in both academia in industry. Many existing knowledge graphs are either available as Linked Open Data, or they can be exported as RDF datasets enhanced with background knowledge in the form of an OWL 2 ontology. Faceted search is the de facto approach for exploratory sear...

Faceted search is the de facto query paradigm in e-commerce and it has been recently adapted for the Semantic Web. In this demonstration we present our faceted search system SemFacet and show how it can enhance access to RDF and OWL 2 datasets and OWL 2 ontologies in the domain of life sciences. SemFacet combines keyword and faceted search and it is based on a solid theory, in particular it emp...
متن کاملInteractively using Semantic Web knowledge: Creating scalable abstractions with FacetOntology
The amount of knowledge accessible on the Semantic Web is growing, and there is a need for a scalable solution to facilitate exploring that data. Currently approaches to exploring Semantic Web data either focus on exploring resources individually, following links during exploration, and making little use of collated data, or take the approach of collating and aligning multiple sources into one ...
