Big data analysis

Currently emerging “big data” techniques are reshaping many fields of science into data science. The Advanced Systems Analysis (ASA) Program in 2013 began developing tools to gain added value from large data clusters.

Global data

For the Austrian National Member Organization, ASA studied the field of medicine, where big data analysis is already shaping the understanding of diseases.

A unique dataset of all Austrian patients under medical treatment for diabetes was compiled in 2006-2007 comprising detailed data on 325,000 patients. Using this large database, scientists revealed a significant extra risk of developing diabetes triggered by undernourishment in early life [1]. Other scientists identified diabetic co-morbidities, both well-known (such as retinopathies, hypertension, chronic kidney diseases etc.) [2] [3] and some not known earlier (such as epilepsy, sepsis, mental disorders).

In 2013 ASA began to develop tools that will allow added value to be gained from large data collections.
