Research

In 1997 Prof. Mentzas established, and has since been leading, the Information Management Unit (IMU) http://imu.ntua.gr, a research laboratory at the National Technical University of Athens.

The mission of IMU is to enable the development of knowledge-driven organizations. IMU focuses on technological research in the areas of: knowledge & semantic technologies; service and process engineering; and decision management, while the major application domains are within the domains of: digital enterprise systems; electronic governance; and collaborative and social systems.

IMU is a member of the Big Data Value Association (BDVA), a fully self-financed non–for-profit organization, which aims to boost European Big Data Value research, development and innovation and of the Networked European Software and Systems Initiative (NESSI), the European Technology platform dedicated to Software and Services.

Since its establishment IMU has actively contributed in fifty-three (53) research and development projects.

The total funding from research grants administered by IMU since 1997 exceeds 14.0 million euros (as of March 2019).
