Yannis Ioannidis is currently a Professor at the Department of Informatics and Telecommunications of the University of Athens. He received his Diploma in Electrical Engineering from the National Technical University of Athens in 1982, his MSc in Applied Mathematics from Harvard University and his Ph.D. degree in Computer Science from the University of California at Berkeley in 1986. Immediately after that he joined the faculty of the Computer Sciences Department of the University of Wisconsin at Madison, where he became a Professor before finally leaving in 1999.

Dr Ioannidis was the recipient of the Presidential Young Investigator (PYI) award in 1991 awarded by the President of the United States to the top young scientists in each field. He has also received the "10-Year Best Paper Award" in the 2003 VLDB Conference and five Teaching Awards, including the "Chancellor's Distinguished Teaching Award", from the University Of Wisconsin at Madison.

His research interests include database and information systems, digital libraries, personalization, scientific systems and workflows and human-computer interaction, topics on which he has published over seventy articles in leading journals and conferences.

He has participated in several research and development projects in the above fields, including DELOS, BRICKS, and DILIGENT. Between July 2002 and March 2004 he served as the Information Technology advisor to the Minister of Health of Greece.

Ioannidis, Yannis E., Saulys, Tomas and Whitsitt, Andrew J. (1992): Conceptual Learning in Database Design. In ACM Transactions on Information Systems, 10 (3) pp. 265-293

This paper examines the idea of incorporating machine learning algorithms into a database system for monitoring its stream of incoming queries and generating hierarchies with the most important concepts expressed in those queries. The goal is for these hierarchies to provide valuable input to the database administrator for dynamically modifying the physical and external schemas of a database for improved system performance and user productivity. The criteria for choosing the appropriate learning algorithms are analyzed, and based on them, two such algorithms, UNIMEM and COBWEB, are selected as the most suitable ones for the task. Standard UNIMEM and COBWEB implementations have been modified to support queries as input. Based on the results of experiments with these modified implementations, the whole approach appears to be quite promising, especially if the concept hierarchy from which the learning algorithms start their processing is initiated with some of the most obvious concepts captured in the database.

Computer programs emerge as the outcome of complex human processes of cognition, communication and negotiation, which serve to establish the meaningful embedding of the computer system in its intended use context.

-- Floyd, 1992, p. 24
