Multidimensional Big Data Analytics over Big Web Knowledge Bases: Models, Issues, Research Trends, and a Reference Architecture

 

Abstract: Big Web Knowledge Bases are actual extensions of well-known knowledge bases where the data layer is composed by big data repositories. These repositories include: social networks, e-government bases, biomedical banks, industry 4.0 web repositories, and so forth. In this context, one of the most relevant research challenges is represented by the issue of supporting big data analytics over such systems, by achieving all the benefits deriving from knowledge discovery and decision making. Multidimensional big data analytics is an emerging paradigm within the more general big data analytics research context, where the main emphasis is
in engrafting fortunate multidimensional metaphors inherited by previous OLAP and BI experiences into the main big data analytics process. Inspired by this scientific blueprint, in this talk we provide models, issues and research trends related to the goal of supporting multidimensional big data analytics paradigms over big Web knowledge bases. Furthermore, we provide a reference architecture that implements this novel paradigm, by strictly following its foundations and its axioms.
