referenceKnowledge reasoning tasks are divided into single-hop prediction and multi-hop reasoning (Ren et al. 2022).
claimSingle-hop prediction predicts one element of a triplet for given two elements, whereas multi-hop reasoning predicts one or more elements in a multi-hop logical query.
referenceMulti-hop reasoning on massive knowledge graphs is a challenging task (Zhu et al. 2022) because most existing studies focus on smaller graphs with only 63K entities and 592K relations.
claimMulti-hop reasoning achieves more precise formation of triplets compared to single-hop prediction, making it a critical need for the development of knowledge graphs.
referenceRen et al. (2022) published 'Smore: Knowledge graph completion and multi-hop reasoning in massive knowledge graphs' in the Proceedings of the 28th ACM SIGKDD Conference on Knowledge Discovery and Data Mining, which addresses the challenges of knowledge graph completion and reasoning at scale.
referenceMulti-hop reasoning requires traversing multiple relations and intermediate entities, which can lead to exponential computation costs (Zhang et al. 2021).
claimExisting multi-hop reasoning models cannot effectively learn from training sets for massive knowledge graphs containing millions of entities.

Large Language Models Meet Knowledge Graphs for Question ... arxiv.org arXiv Sep 22, 2025 3 facts
referenceThe HippoRAG method (Gutiérrez et al., 2024) identifies relevant knowledge graph subgraphs by integrating multi-hop reasoning with single-step multi-hop knowledge retrieval.
claimIncorporating knowledge graphs with LLMs enables multi-hop and iterative reasoning over factual knowledge graphs, which augments the reasoning capability of LLMs for complex question answering.
claimRAG-based question answering systems face three primary technical challenges: (1) knowledge conflicts arising from inconsistent or overlapping data between LLMs and external sources, (2) poor relevance and quality of retrieved context which directly impacts answer accuracy, and (3) a lack of iterative and multi-hop reasoning capabilities required for questions needing global or summarized contexts.
