Introduction for Fall 2020
More up to date information about the course will be added soon. The information below belongs to the course in Fall 2019.
Course Introduction
TDT44 Semantic Web: a Specialization module complementary to TDT4175 Information Systems. Other IS modules can be found here.
TDT44 will be taught by Özlem Özgöbek in the fall 2019.
We will use the following book: https://link.springer.com/book/10.1007/978-3-319-45654-6 (free electronic copy for NTNU students)
About the course
The students get an orientation of the theoretical, methodological and technological background and of the ongoing standardization work that support semantic Web.
You will gain:
- Background theoretical knowledge
- Insight to relevant problems within Web information resources and services
- Insight to how to use semantic web technology to solve problems in different domains
Mandatory activities: Peer review, project report, final presentation.
Final grade: Project report and final presentation.

Readings in TDT44 Semantic Web (2019)
The book we will use is: Exploiting Linked Data and Knowledge Graphs in Large Organisations.
Please order the book now, so you have it ready for the first class in September!
You can also download it for free on the NTNU-network from here: https://link.springer.com/book/10.1007/978-3-319-45654-6
You may also read two papers, on Logics and Turtle, and if you are interested (proposed by a student 2016):
- The Unreasonable Effectiveness of Data.pdf is not really about the Semantic Web, but I post it here as a good read for those who like that.
- https://www.w3.org/TR/owl2-primer/ might be useful when comparing RDF vs. Turtle etc.

Obligatory Individual Assignment
More information will come.
Obligatory Obligatory assignment is now available.(2019)
The deadline is 25.11.2019. Please send your reports by e-mail.
...
During the oral exam, each student will have 20 minutes. This includes the presentation of the individual assignment and questions from the sensors. For the presentation you don't need any slides, so don't prepare any slides. We will ask you to explain your assignment orally, you can use a white board if needed. Please bring a printed copy of your report with you. Questions from sensors will include details from your assignment and some basic knowledge from the book.
