13Toward Evolving Knowledge Ecosystems for Big Data Understanding
research and development projects and focus on what they do in advanc-
ing the state-of-the-art in semantic technologies for Big Data processing.
Further, we summarize the analysis by pointing out the observed complica-
tions and overheads in processing Big Data semantics. Finally, we outline a
high-level proposal for the renement of the Big Data semantics layer in the
technology stack.
Big Data Processing—Technology Stack and Dimensions
At a high level of detail, Driscoll (2011) describes the Big Data processing
technology stack comprising three major layers: foundational, ...
