Course description
Semantic Web is a maturing field of technology that continues to be the emphasis of much focused research and industrial investigation. Its central idea is to add meaning (semantics) to the data on the Web thus making it machine processable. In this course we cover the standardized knowledge representation languages for enriching the data with meaning. More specifically, on the theoretical side we will study the syntax and semantics of the main ontology and rule-based languages. On the practical side we will exploit the available tools for the knowledge representation and reasoning.
Prerequisites
The basic knowledge of first order logic is highly recommended.
Examination modalities
Exercises:
2 exercise sheets will be handed out. The exercises should be solved at home. Students can check the examples they solved; checkmarks may be changed arbitrarily until the deadline. Afterwards there will be a discussion of the solutions in small groups. To this end, 1 hour slots will be offered (3 students simultanously). The week days for the slots are Tuesday and Thursday.
Both checkmarking the exercises and registering for a discussion slot should be done until Jan 15 2018, 23:55 (strict deadline).
In the discussion, students will be asked questions about their solutions of examples they checked. The discussion will be evaluated with 0-10 points, which are weighted with the fraction of checked examples and rounded to the next integer.
Example: Student X checked 70% of the examples and the discussion is evaluated with 8 points. Therefore he gets 6 exercise points.
In case a student does not participate in the discussion, no exercise points will be awarded.
Projects:
In addition to the 2 exercise sheets, 2 projects must be solved using ontologies (Project 1) and answer set programming (Project 2):
- Project 1 will be manually graded with mandatory discussion timeslot in small groups
- Project 2 will be automatically graded with testcases. The discussion of Project 2 solutions will be arranged jointly with the final consultation, which students should attend in case they have any questions
Project submission deadlines:
- Project 1: Jan 17 2018, 23:55
- Project 2: Jan 26 2018, 23:55
