ExpLOD: Summary-Based Exploration of Interlinking and RDF Usage in the Linked Open Data Cloud Summary: Publishing interlinked RDF datasets as links between data items identified using dereferenceable URIs on the web brings forward a number of issues. A key challenge is to understand the data, the...
Real-Time RDF Extraction from Unstructured Data Streams The vision behind the Web of Data is to extend the current document-oriented Web with machine-readable facts and structured data, thus creating a representation of general knowledge. However, most of the Web of Data is limited to being a....

Technologies such as the Resource Description Framework (RDF) [12], OWL, SPARQL Protocol and RDF Query Language (SPARQL) [15], and Semantic Web Rule Language (SWRL) [5], introduce a set of basic technologies to describe the data, to model ontologies, to describe semantic database queries,...
Furthermore, we present the semantic wiki KiWi, which uses an RDF triplestore in combination with a relational database as basis for the persistence of data, and discuss its concrete implementation and design decisions. 1 展开 被引量: 32 ...
We showcase the KnowledgeStore, a scalable, fault-tolerant, and Semantic Web grounded framework for interlinking unstructured (e.g., textual documents, web pages) and structured (e.g., RDF, LOD) contents, enabling to jointly store, manage, retrieve, and query, both typologies of contents.会议...

Using our ontology framework, we created a graph database and constructed the knowledge graphs. In this work, we suggest an approach to use a combination of both machine and human-curated knowledge to build the ontology. The second challenge was how to parse a large amount of text in other...
