Short description:

The course introduces logic as a method for computational problem solving. It introduces multiple practical logics and logic based systems such as logic programs, modal logics, description logics and ontologies, multi context systems, etc. with readily available reasoners.

Offered in these study programs: Compulsory elective for the Master program in Applied Informatics

Recommendations: none

Basic Information

MIDTERM: Wednesday, November 3th, 9:50 (room C !!! )

you can expect tasks as follows:

- conceptualization (a translation from natural language to the language of first-order logic)

- resolution

- semantic notions (interpretation, model, entailment); f.ex. a set of formulae is given, propose an interpretation, which is (or is not) a model of the set; decide whether a fomula is entailed by the set

Evaluation and Conditions

There will be a midterm and a final exam. During the semester you can earn evaluation points at the practicals (possibly for homeworks) and by participating on the wiki-based collaborative lecture notes. You can earn up to 102 points:

• practicals: 3 pts every week (6 weeks)
• lecture notes: 3 pts every week (13 weeks)
• midterm: 15 pts
• exam: 30 pts

The following grading scale will be used:

• A = 85 pts and more
• B = 74 pts and more
• C = 64 pts and more
• D = 54 pts and more
• E = 45 pts and more
• Fx = less than 45 pts

Lecture Notes

There is no coherent study-material for this course. You are advised to take notes. To facilitate this, we have created dedicated lecture-notes pages in the students' wiki where you are all asked to regularly contribute in a collaborative fashion. Your goal is to keep coherent, full-scope, up-to-date lecture notes, covering all material from the lectures. And at least briefly, also the practicals. For your activity you can earn up to 3 pts per week. Visit the lecture notes.
