Semantic Analysis of Unstructured Data

Big data is a much-hyped subject. In fact, the term is rather misleading because it seems to relate only to the volume of data, while ignoring its heterogeneous nature. Accordingly, the general definition of "big data," as suggested by Gartner, also considers the complexity and variety of data, thus focusing on the relevance of highly heterogeneous and unstructured information and how it can be analyzed in various forms. In particular, apart from the growing network of machines and equipment, social interactions are a further source of big data. With the exchange of messages in a wide variety of formats, on various platforms, and through multiple channels, large amounts of data are generated that demand analysis and interpretation.
