About Us

Big Data Lab is an organisation dedicated to the promotion and dissemination of Big Data.

Our Vision

With the development of information technology, more and more information, often described as Big Data, is being made available in electronic form.

Both industry and academia are pioneering data science techniques, but their use is limited to a few organisations and has not yet reached widespread adoption.

Our mission is to contribute to the creation of a sustainable society by promoting logical decision-making through the spread of data science.
