New method constructs tree knowledge graphs for low-resource languages

By PulseAugur Editorial · [1 sources] ·

Researchers have developed an end-to-end pipeline for constructing tree knowledge graphs and evaluating retrieval strategies, specifically addressing the challenge of low-resource languages like Vietnamese. The system employs a hybrid relation extraction pipeline, including deduplication and LLM-based extraction with a validator, to build the knowledge graph. Evaluation of graph traversal strategies on Vietnamese history textbooks showed that a Top-Down approach outperformed a vector baseline in NDCG@10, indicating the value of structural information in retrieval.

IMPACT This research offers a novel approach to building knowledge graphs for low-resource languages, potentially improving RAG systems in diverse linguistic contexts.

    Automated Tree Knowledge Graph Construction using Ontology Expansion and Retrieval from Vietnamese History Textbooks

    arXiv:2609.00763v1 Announce Type: new Abstract: Hierarchical Knowledge graph (KG)-based retrieval augmented generation (RAG) has emerged as a powerful approach for supporting large language models with structured knowledge. However, there are primary challenges: (i) the lack of m…
