Obligatory Individual Assignment 2020
You can choose one of the following obligatory assignments:
Option 1:
Write a report (max 10 pages) on a topic of your choice (to be agreed upon with the teacher).
You can choose a topic which will be close to your master thesis topic. You are not allowed to copy text from this report to your thesis or fall report, but you can re-use the ideas and insight you gain.
While deciding on the topic it is recommended to talk to your supervisor.
Option 2:
Develop an RDF(S) ontology (or a dictionary) on a chosen topic (to be agreed upon with the teacher) and write a short report (max 5 pages) explaining the details of your work.
Explain every aspect of your ontology. Explain the assumptions underlying your ontological choices.
The ontology should not exceed 30 classes and 30 instances. The modeling language should be Turtle or a similar syntax. You can use any modeling software.
If you choose this task, you may refer to the individual assignments in the previous years in this course.
Mandatory peer feedback:
Document to submit: (Deadline: 5 November 2020)
For this task please prepare a 1-2 page document where you explain your obligatory assignment in more detail.
Peer feedback: (Deadline: 10 November 2020)
After submitting your document to peergrade, you will be able to see the feedback form. There is an explanation of the task in the system.
More information has been sent by e-mail.
