FITTER: Vocabulary-Agnostic Cross-Domain Inference on Temporal Knowledge Graphs
Jiaxin Pan, Mojtaba Nayyeri, Osama Mohammed +4
Temporal knowledge graphs are central to many uses of the Semantic Web, but existing completion methods assume the entities, relation names, and timestamps to be reasoned about are…
STEREODISCO: Discovering Stereotypicality in LLMs
Farane Jalali Farahani, Corina Dima, Mojtaba Nayyeri +2
The paper introduces STEREODISCO, a framework that discovers stereotypical semantic axes in large language models by probing their activation spaces using WordNet antonym pairs, an…
Approximating Probabilistic Inference in Statistical EL with Knowledge Graph Embeddings
Yuqicheng Zhu, Nico Potyka, Bo Xiong +4
Statistical information is ubiquitous but drawing valid conclusions from it is prohibitively hard. We explain how knowledge graph embeddings can be used to approximate probabilisti…
Leveraging Graph Structure in Seq2Seq Models for Knowledge Graph Link Prediction
Luu Huu Phuc, Ratan Bahadur Thapa, Mojtaba Nayyeri +3
We introduce Graph-Augmented Sequence-to-Sequence (GA-S2S), a novel framework that integrates a T5-small encoder-decoder with a Relational Graph Attention Network (RGAT) to improve…
Towards Foundation Models for Relational Databases with Language Models and Graph Neural Networks
Jingcheng Wu, Ratan Bahadur Thapa, Mojtaba Nayyeri +4
Relational databases store much of the world's structured information, and they are essential for driving complex predictive applications. However, deep learning progress on relati…
Geometric Structural Knowledge Graph Foundation Model
Ling Xin, Mojtaba Nayyeri, Zahra Makki Nayeri +1
Structural knowledge graph foundation models aim to generalize reasoning to completely new graphs with unseen entities and relations. A key limitation of existing approaches like U…
