Knowledge Graphs in the Age of Large Language Models

Gerhard Weikum (Max Planck Institute for Informatics, Saarbruecken, Germany)

Abstract
Large knowledge graphs (KG's) have become a key asset for search engines and other use cases. They are partly based on automatically extracting structured information from web contents and other texts, using a variety of pattern-matching and machine-learning methods. The semantically organized machine knowledge can be harnessed to better interpret text in news, social media and web tables, contributing to question answering, natural language processing (NLP) and data analytics.
 
A recent trend that has revolutionized NLP is to capture knowledge latently by billions of parameters of language models (LM's), learned at scale from huge text collections in a largely self-supervised manner. These pre-trained models form the basis of fine-tuning machine-learning solutions for tasks that involve both input texts and broad world knowledge, such as question answering, commonsense reasoning and human-computer conversations.
 
This talk identifies major gaps in the coverage of today's KG's, and discusses potential roles of large language models towards narrowing thee gaps and constructing the next KG generation.

Short Biography
Gerhard Weikum is a Scientific Director at the Max Planck Institute for Informatics in Saarbruecken, Germany, and an Adjunct Professor at Saarland University. He co-authored a comprehensive textbook on transactional systems, received the VLDB Test-of-Time Award 2002 for his work on automatic database tuning, and is one of the creators of the YAGO knowledge base which was recognized by the WWW Test-of-Time Award in 2018. Weikum is an ACM Fellow and elected member of various academies. He received the ACM SIGMOD Contributions Award in 2011, a Google Focused Research Award in 2011, an ERC Synergy Grant in 2014, the ACM SIGMOD Edgar F. Codd Innovations Award in 2016, and the Konrad Zuse Medal in 2021.

Mission

To build an AI Excellence Hub in Greece where the international research community can connect, groundbreaking ideas can thrive, and the next generation of scientists emerges, shaping a brighter future for Greece and the world

 

Welcome to ARCHIMEDES, a vibrant research hub connecting the global AI and Data Science research community fostering groundbreaking research in Greece and beyond. Its dedicated core team, comprising lead researchers, affiliated researchers, Post-Docs, PhDs and interns, is committed to advancing basic and applied research in Artificial Intelligence and its supporting disciplines, including Algorithms, Statistics, Learning Theory, and Game Theory organized around 8 core research areas. By collaborating with Greek and Foreign Universities and Research Institutes, ARCHIMEDES disseminates its research findings fostering knowledge exchange and providing enriching opportunities for students. Leveraging AI to address real-world challenges, ARCHIMEDES promotes innovation within the Greek ecosystem and extends its societal impact. Established in January 2022, as a research unit of the Athena Research Center with support from the Committee Greece 2021, ARCHIMEDES is funded for its first four years by the EU Recovery and Resilience Facility (RRF).

Applications for the Greek Olympiad in Artificial Intelligence for Middle and High School Students are Now Open!

Applications for the Greek Olympiad in Artificial Intelligence for Middle and High School Students are Now Open!

The Preliminary Phase "Talos" of the Greek Olympiad in Artificial Intelligence (PDTN) is now open for online participation. This competition for middle and high school students will run from December 1, 2025 until March 1, 2026, and students will be asked to solve four problems: one on Decision Trees (Δεντρα Αποφασης), one on CAPTCHA Challenges (Επίλυση CAPTCHA), one for Emotion Classification (Συναισθηματα), and one on Movie Recommendation Systems (Επόμενη Ταινία).

 
 

The project “ARCHIMEDES Unit: Research in Artificial Intelligence, Data Science and Algorithms” with code OPS 5154714 is implemented by the National Recovery and Resilience Plan “Greece 2.0” and is funded by the European Union – NextGenerationEU.
