After successful completion of the course, students are able to apply techniques, methods, and algorithms of knowledge-based systems for theoretical and practical applications, as well as to use the gained knowledge in further courses.
Attention:
- Email address for questions: kbsci-2022s AT kr.tuwien.ac.at
- The first lecture is on Wed Mar 09, 2022.
- Mandatory TISS course registration until Mar 10, 2022.
- Mandatory TUWEL entry test from Mar 11 to Mar 13, 2022 (00:00-23:55). Everybody who takes the entry test will receive a certificate (i.e., it is not possible to unregister after the entry test). If you stop participating after taking the entry test, you will receive a negative certificate.
The module discusses the following topics:
- Rule-based systems and RETE
- Predicate Logic (as a representation language)
- Description Logics (ALC, Basics, Tableau)
- Truth Maintenance Systems
- Answer Set Programming
- Probabilistic Reasoning
Lecturers
Lecture-Part: Uwe Egly, Thomas Eiter, and Hans Tompits
Exercise-Part: Antonius Weinzierl
Course of Action and Topics of the Lecture Part
Attention: This semester, the course is planned to be held as a mixed presence/online course, with a possible fall-back to a pure online course depending on the COVID situation. The final exam is oral and also depending on the situation, it will be held in presence or online. Moreover, the exercise test is in written form and also for that the COVID situation will determine whether it will be held in presence or online form.

Exercise-Part
Mandatory registration until Mar 11, 2020.
Mandatory TUWEL entry test from Mar 11 to Mar 13, 2022 (00:00-23:55). Everybody who takes the entry test will receive a certificate (i.e., it is not possible to unregister after the entry test).
Exercise test which covers 3 exercise sheets
Mandatory (closed book) exercise test on June 10, 14:00-16:00. The test examines the following three exercise sheets and their background:
- Sheet 1: Rules + Predicate Logic
- Sheet 2: Description Logics + Truth Maintenance Systems
- Sheet 3: Answer Set Programming + Probabilistic Reasoning
- The exercise test is closed book and planned to be in presence, otherwise (depending on the COVID situation) in online form for which the following infrastructure is required: stable internet connection, a device with webcam and microphone, either a printer or a second device to view a PDF, and a scanner or camera with software to generate a single PDF of the written test.
Tutor hours will be available for questions (see TUWEL).
The test is evaluated with up to 27 points.
