Fuzzy Logic Based Logical Query Answering on Knowledge Graphs

no code implementations5 Aug 2021 Xuelu Chen, Ziniu Hu, Yizhou Sun

Answering complex First-Order Logical (FOL) queries on large-scale incomplete knowledge graphs (KGs) is an important yet challenging task.

Probabilistic Box Embeddings for Uncertain Knowledge Graph Reasoning

1 code implementation NAACL 2021 Xuelu Chen, Michael Boratko, Muhao Chen, Shib Sankar Dasgupta, Xiang Lorraine Li, Andrew McCallum

Knowledge bases often consist of facts which are harvested from a variety of sources, many of which are noisy and some of which conflict, resulting in a level of uncertainty for each triple.

Knowledge Graph Embedding

Multilingual Knowledge Graph Completion via Ensemble Knowledge Transfer

1 code implementation Findings of the Association for Computational Linguistics 2020 Xuelu Chen, Muhao Chen, Changjun Fan, Ankith Uppunda, Yizhou Sun, Carlo Zaniolo

Predicting missing facts in a knowledge graph (KG) is a crucial task in knowledge base construction and reasoning, and it has been the subject of much research in recent works using KG embeddings.

Embedding Uncertain Knowledge Graphs

1 code implementation26 Nov 2018 Xuelu Chen, Muhao Chen, Weijia Shi, Yizhou Sun, Carlo Zaniolo

However, there are many KGs that model uncertain knowledge, which typically model the inherent uncertainty of relations facts with a confidence score, and embedding such uncertain knowledge represents an unresolved challenge.
