Guided by data and objectives

Dr. el Abed’s journey began in the 1990s when, as a student, he took a keen interest in the prospect of automating the dialogue between man and machine. This interest led him to study linguistics and computer science. In 1995, Dr el Abed created Data Excellence Science, a study that integrates computer science, linguistics, business management and AI to process natural language (semantics) and transform it into IT language (code).

Dr el Abed’s scientific discipline is the foundation of the AI platform DEMS (Data Excellence Management System). Today, Data Excellence Science is taught in several leading universities in France and Switzerland such as the University of Franche-Comté, the University of Fribourg and the Conservatoire National des Arts et Métiers de Paris.

A revolutionary technology

In recent years, DEMS has become an attractive proposition for organizations and is considered a revolutionary technology in data and AI governance. “Currently, Global Data Excellence (GDE) is funded by the European Commission and in a very short period of time organizations from both the public and private sectors have invested in us. A major driver of our success is the time to value production, which is currently unmatched in the industry,” explains Dr Walid el Abed.
