Each graph is a new language: Graph Learning with LLMs (2025.findings-acl)

Copied to clipboard

Challenge: Natural language is used to describe graphs, but graph descriptions become verbose and only relying on attribute embeddings limits LLM’s ability to capture adequate graph structural information.
Approach: They propose a graph-defined language for large language model that translates the graph into a corpus instead of graph descriptions and pre-trains LLMs on this corpus to adequately understand the graph.
Outcome: Experiments on five datasets show that the proposed framework outperforms description-based and embedding-based baselines by efficiently modeling different orders of neighbors.

Improving Multilingual Translation by Representation and Gradient Regularization (2021.emnlp-main)

Copied to clipboard

Challenge: Multilingual Neural Machine Translation models often produce low quality translations, often failing to produce outputs in the right target language.
