The Resource Description Framework (RDF) represents a main ingredient and data
representation format for Linked Data and the Semantic Web. It supports a generic graph …

Exhaustive enumeration of all possible join orders is often avoided, and most optimizers
leverage heuristics to prune the search space. The design and implementation of heuristics …

In this paper we address the problem of scalable, native and adaptive query processing over
Linked Stream Data integrated with Linked Data. Linked Stream Data consists of data …

The proliferation of camera-enabled devices and large video repositories has led to a
diverse set of video analytics applications. These applications rely on video pipelines …

DryadLINQ is a system and a set of language extensions that enable a new programming
model for large scale distributed computing. It generalizes previous execution environments …

We study the problem of optimizing subgraph queries using the new worst-case optimal join
plans. Worst-case optimal plans evaluate queries by matching one query vertex at a time …

This article addresses the profitability problem associated with auto-parallelization of
general-purpose distributed data stream processing applications. Auto-parallelization …

In this paper we discuss advances in self-tuning database systems over the past decade,
based on our experience in the AutoAdmin project at Microsoft Research. This paper …

After four decades of research, today's database systems still suffer from poor query
execution plans. Bad plans are usually caused by poor cardinality estimates, which have …

Following the design rules of Linked Data, the number of available SPARQL endpoints that
support remote query processing is quickly growing; however, because of the lack of …
