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.

Examination Dates and Mode

The registration and scheduling for exams depends on the module that the exam is for. All students need to contact the KBS secretary to arrange time slots for their oral exams, or the secretary of another chair in case of another main examiner. Although we cannot generally accommodate wishes for specific dates, students who have justified time constraints during the examination period can still let us know as early as possible.

For obtaining credits in module CMS-COR-KM, students have to take an exam that only involves this one course. This exam is either written or oral, depending on the number of registered students (as per the study regulations). Repetition exams in CMS-COR-KM in Summer 2024 will usually happen on Tue, 6th August 2024. We only expect oral exams, but the final mode can only be announced when registration is complete.

Students who are taking Knowledge Graphs as part of any other module should contact the secretary of the main examiner to find a date. If the main examiner is Markus Krötzsch, the preferred date will also be 6th August 2024.
