Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Course-unit credit requirements: active attendance at the seminars, creating simple expert system applications.
Examination: written test (simple problems and theoretical questions), oral exam.

Language of instruction


Work placements

Not applicable.


The goal of the course is to make students familiar with the principles of working expert systems. They will acquire fundamentals of knowledge engineering.

Specification of controlled education, way of implementation and compensation for absences

Attendance at the seminars is controlled. An absence can be compensated for via solving given problems.
