On the 22.05.2025, we will start the new year with our next alumni talk by Sven Hertling.
Sven Hertling is a substitute professor for Data Science at the University of Mannheim.
His research is about generating large-scale knowledge graphs and especially on their integration.
He did his post-doc at the Chair for Information Service Engineering (FIZ Karlsruhe) with the focus on knowledge graph generation using LLMs.
The PhD thesis with the title “Knowledge Graph Generation and Integration at Scale” was completed at the School of Business Informatics and Mathematics (University of Mannheim) with a summa cum laude.
Sven holds a B.Sc. and M.Sc. degree in computer science from the Technical University of Darmstadt, Germany.
Title: Knowledge Graph Generation – the Past and the Future
Time: 22.01.2025 12:00 CET
Abstract:
Knowledge graphs (KGs) have emerged as powerful tools for organizing and representing structured knowledge
through entities, relationships, and links to other datasets.
In this presentation, common KGs such as DBpedia and YAGO and their generation are introduced.
Afterwards, more recent KGs like CaLiGraph and DBkWik will be presented as well as the challenges of data integration and ontology refinement.
In the last part, modern approaches using large language models (LLMs) are analyzed
and critical challenges such as scalability and memorization of online test data are addressed.
The talk will take place online via Google Meet. No registration is needed.
