RDF Database Systems is a cutting-edge guide that distills everything you need to know to effectively use or design an RDF database. This book starts with the basics of linked open data and covers the most recent research, practice, and technologies to help you leverage semantic technology. With an approach that combines technical detail with theoretical background, this book shows how to design and develop semantic web applications, data models, indexing and query processing solutions. Understand the Semantic Web, RDF, RDFS, SPARQL, and OWL within the context of relational database management and NoSQL systems Learn about the prevailing RDF triples solutions for both relational and non-relational databases, including column family, document, graph, and NoSQL Implement systems using RDF data with helpful guidelines and various storage solutions for RDF Process SPARQL queries with detailed explanations of query optimization, query plans, caching, and more Evaluate which approaches and systems to use when developing Semantic Web applications with a helpful description of commercial and open-source systems
We provide techniques to incrementally maintain the index and the graph saturation upon the changes to the RDF graph, enabling the framework to cope with dynamic data graphs. Experiment results demonstrate that our techniques ...
Records r1 and r2 can be seen as a matching pair according to dual levels—attribute level (title, manufacturer) and token level (microsoft, word, 2004, etc.). entity. Due to the inherent hierarchical structure of the relational records, ...
This two volume set LNCS 5981 and LNCS 5982 constitutes the refereed proceedings of the 15th International Conference on Database Systems for Advanced Applications, DASFAA 2010, held in Tsukuba, Japan, in April 2010.
Currently, concepts from traditional approaches of federated query processing systems are adapted to provide integrated access to RDF data sources. Basic idea is to query a mediator, which distributes subqueries to local RDF stores and ...

2.3 System Framework The framework (cf. Fig. 1) consisted of three components, including getting the EDP representation of RDF data, generating EDPRule from the ontologies of RDF data, using EDPRule and EDP to detect redundant triples.
Recently, how to evaluate SPARQL queries over federated RDF systems has become a hot research topic. However, most existing studies mainly focus on implementing and optimizing the basic queries over federated SPARQL systems, ...
With this practical book, you’ll learn how to design and implement a graph database that brings the power of graphs to bear on a broad range of problem domains.
