TL;DR: Recent research in data types, storage models, privacy, data security, analysis methods, and applications related to network big data are reviewed.

TL;DR: In this article, a relaxation of justified representation, called Proportional Justified Representation (PJR), is proposed, which is more demanding than justified representation but compatible with perfect representation.

TL;DR: Two algorithms are proposed for the composition of QoS-aware service-based applications with temporal requirements: an exhaustive algorithm that computes the optimal service combination in terms of a figure of merit, suitable for offline composition; and an improved algorithm based on heuristics and partial figures of merit suitable for online composition.

TL;DR: This paper deals with the definition of a time-critical big- data system from the point of view of requirements, analyzing the specific characteristics of some popular big-data applications and proposing an architecture and offering initial performance patterns that connect application costs with infrastructure performance.

TL;DR: This article provides a set of improvements to a computational model called distributed stream processing in order to formalize it as a real-time infrastructure and proposes some extensions to Storm, one of the most popular stream processors.
