Graph Fusion Across Languages using Large Language Models
This addresses the challenge of semantic heterogeneity in multilingual knowledge graphs, offering a scalable solution for continuous knowledge synthesis, though it appears incremental in its approach.
The paper tackles the problem of combining knowledge graphs across languages by using Large Language Models to map relations and reconcile entities, achieving successful sequential agglomeration on the DBP15K dataset.
Combining multiple knowledge graphs (KGs) across linguistic boundaries is a persistent challenge due to semantic heterogeneity and the complexity of graph environments. We propose a framework for cross-lingual graph fusion, leveraging the in-context reasoning and multilingual semantic priors of Large Language Models (LLMs). The framework implements structural linearization by mapping triplets directly into natural language sequences (e.g., [head] [relation] [tail]), enabling the LLM to map relations and reconcile entities between an evolving fused graph ($G_{c}^{(t-1)}$) and a new candidate graph ($G_{t}$). Evaluated on the DBP15K dataset, this exploratory study demonstrates that LLMs can serve as a universal semantic bridge to resolve cross-lingual discrepancies. Results show the successful sequential agglomeration of multiple heterogeneous graphs, offering a scalable, modular solution for continuous knowledge synthesis in multi-source, multilingual environments.
