The D2RQ Platform is a system for accessing relational databases as virtual, read-only RDF graphs. It offers RDF-based access to the content of relational databases without having to replicate it into an RDF store. Using D2RQ you can: query a non-RDF database using SPARQL access the content of the database as Linked Data over the Web create custom dumps of the database in RDF formats for loading i
1. The document discusses knowledge representation and deep learning techniques for knowledge graphs, including embedding models like TransE, TransH, and neural network models. 2. It provides an overview of methods for tasks like link prediction, question answering, and language modeling using recurrent neural networks and memory networks. 3. The document references several papers on knowledge gra

Redland is a set of free software C libraries that provide support for the Resource Description Framework (RDF). Modular, object based libraries and APIs for manipulating the RDF graph, triples, URIs and Literals. Storage for graphs in memory and persistently with Oracle Berkeley DB, MySQL 3-5, PostgreSQL, OpenLink Virtoso, SQLite, files or URIs. Support for multiple syntaxes for reading and writi
This Working Group ended its activities on 1 July 2014 and is now closed. Its mission was to update the 2004 RDF Recommendations, extending RDF to include features desirable and important for interoperability, but without a negative effect on deployment. (See Charter) Deliverables Recommendations RDF 1.1 Concepts and Abstract Syntax RDF 1.1 Semantics JSON-LD 1.0 JSON-LD 1.0 Processing Algorithms a
If you plan to run the benchmark to test your own implementation, you can find both the data generator and benchmark queries at our download section. Abstract Recently, the SPARQL query language for RDF has reached the W3C recommendation status. Addressing the needs of this new standard, the database community is currently exploring efficient storage techniques for RDF data and evaluation strategi
