Yago: a core of semantic knowledge
YAGO builds on entities and relations and currently contains more than 1 million entities and 5 million facts, which includes the Is-A hierarchy as well as non-taxonomic relations between entities (such as HASONEPRIZE).

A robust method for collective disambiguation is presented, by harnessing context from knowledge bases and using a new form of coherence graph that significantly outperforms prior methods in terms of accuracy, with robust behavior across a variety of inputs.

The RDF-3X engine for scalable management of RDF data
The RDF-3X engine is presented, an implementation of SPARQL that achieves excellent performance by pursuing a RISC-style architecture with streamlined indexing and query processing, and can outperform the previously best alternatives by one or two orders of magnitude.
RDF-3X: a RISC-style engine for RDF
The salient points of RDF-3X are a generic solution for storing and indexing RDF triples that completely eliminates the need for physical-design tuning, a powerful yet simple query processor that leverages fast merge joins to the largest possible extent, and a query optimizer for choosing optimal join orders using a cost model based on statistical synopses for entire join paths.
The LRU-K page replacement algorithm for database disk buffering
The LRU-K algorithm surpasses conventional buffering algorithms in discriminating between frequently and infrequently referenced pages, and adapts in real time to changing patterns of access.
