Today, digital research methods are relevant in all branches of knowledge. The digital representation of data represents not only the advent of the era of big data, but also opens up wide opportunities for semantic analysis, which in principle was impossible in analog systems. Semantic analysis means that the functions of digital devices become intelligent, that is, they produce new knowledge and new value. That is why Gartner uses the term “digitalization” to emphasize that the purpose of changes is to create new value for consumers, and not just to improve what has been done within the framework of automation and computerization. Digitalization, big data and artificial intelligence are three related key concepts that the research of the Big Data and Blockchain Technologies Research and Innovation Center focuses on.
