Lecture series
Knowledge graphs are becoming an important paradigm in industry and research, with applications including prominent examples such as Google's own Knowledge Graph, Wikipedia's knowledge base sister Wikidata, and numerous artificial intelligence projects from Alexa to Siri. Meanwhile, companies are exploring the use of their own enterprise knowledge graphs for improving internal knowledge management.
With so many facets, knowledge graphs are a cross-cutting topic in computer science that involves aspects of data management (graph databases, file formats), publication (exchange formats, data integration), knowledge organisation (constraints, ontologies), and advanced analytics (expressive query languages, graph data mining). On each of these levels, there is some interesting theory and some interesting technology to be learned. This course will cover a colourful mix of technologies and methods related to the use of graphs for data analysis, knowledge representation, and data management.
Registration
The course generally does not require a special registration and there is no limit for participants. However, you need to enroll in the OPAL course for one of the exercise sessions. Additionally, students in programmes that use the Selma system (esp. students in CMS Master) will need to register there to obtain credits. Most of the materials will be freely available world-wide. Live sessions (especially tutorials) are restricted to students of TU Dresden.
Examinations in Summer 2023
For the oral exams, we have blocked two dates this term:
- Monday, 2023-07-17
- Friday, 2023-07-28
As usual, you should book a date with our secretary after you have officially enrolled in your respective examination office/system.
The written exam will be on Friday, 2023-08-04, from 08:30–10:00, in SCH/A251. Make sure you are officially enrolled in your respective examination office/system. You do not need to contact our secretary for the written exam.
Examinations
- The type of the examination depends on the study programme (written examination for CMS, oral examination otherwise).
- For CMS students, the written examination will be on Wednesday, 2023-03-01, from 09:20—10:50, in HSZ/E05. Make sure you are registered in Selma. You do not need to contact us.
- For all other students, we have reserved two dates for the oral examinations. As usual, you should book a date with our secretary after you have officially enrolled in your respective examination office/system:
- Tuesday, 2023-02-14, and
- Friday, 2023-03-03.
- Post-exam review: You can review your written exam on Thursday, 2023-04-20, at 13:00 in APB 3027.
Schedule and Location
The lecture will adopt a hybrid format. Lectures will be published as videos, while exercises will be in-person.
All dates are published on this page (see Dates & Materials above)
- Lecture sessions: published as videos, see Dates & Materials above
- Exercise session: two groups, enroll via OPAL.
- The first exercise sessions will take place on Tuesday, 2022-10-18. There will be no exercise sessions on Tuesday 2022-10-11.
- A Q&A session will take place on Tuesday, 2023-02-07, during DS5 (14:50 to 16:20), in APB E005 (see below), where we will discuss, among other questions, the mock exam.
