Course description and aims

Sentences expressed by a language have a meaning. In order to process meanings using a computer, we need to consider logical inference itself as a mathematical object. In this lecture, we learn logic as a basic methodology for this purpose, which provides a foundation for knowledge processing by the formal approach. Particularly, we learn propositional logic, predicate logic, resolution principle, and a logic programming language Prolog.

Student learning outcomes

By the end of this course, students will be able to:
1) explain propositional and predicate logic that formalize inference as symbolic operation
2) write program code using a logic programming language Prolog

Keywords

propositional logic, predicate logic, resolution principle, logic Programming, Prolog

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

Eight lectures about propositional and predicate logic at the first half, and six exercises of Prolog programming at the second half.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Textbook(s)

Handouts are distributed

Reference books, course materials, etc.

Assessment criteria and methods

Exercise is 40%, and the final exam is 60%.
The final exam may be replaced with a report when holding the exam is difficult.
