with large sets of miscellaneous, heterogeneous and unstructured
data. It implies that tools and techniques have to be designed
to disambiguate it before putting it together to master
and manage data of organizations. Our work is similar to [9]
in the approach. We discuss challenges and opportunities of
semantics in the age of Big Data and present the supply chain
to handle it. Therefore, this article defines Big Data (Section 2),
briefly discusses its management (Section 3) and finally tackles
Big Data and semantics challenges and opportunities (Section
4).
