COMPUTER BANKS OF KNOWLEDGE

Note: this presentation has been delivered by the author at theDoctoral Consortium on Enterprise Information Systems,

April 23-26, Angers, France, 2003

information

2. The problem

Information processing systems often turn out to be non-interoperable

3. The aim of the work

A unified web-based bank of knowledge for

- supporting development of interoperable information processing systems,

- supporting the whole information processing cycle,

- supporting coordinated researches on methods of solving various information processing problems (scientific aspect),

- providing trainees with means for solving training tasks in the field of information processing (educational aspect)

They could not be used together for supporting the whole information processing cycle

Other contemporary systems for editing information of different levels of abstraction:

- CUE (by T. Gruber, G. van Heijst, A.Th. Schreiber, B.J. Wielinga et al.)

- Protégé-2000 (by W.E. Grosso, H. Eriksson, R.W. Fergerson, M.A. Musen et al.)
