Knowledge graphs are fundamentally structured as collections of triplets, which consist of subject, predicate, and object components as described in [1] and [2]. Furthermore, triplets are essential for the maintenance and expansion of knowledge graphs, as they are extracted from text to enrich the graph [3] and are evaluated for confidence within the graph structure [4].

procedureGeneration-retrieval frameworks for knowledge graph question answering, such as ChatKBQA (Luo H. et al., 2023) and GoG (Xu et al., 2024), use a two-stage approach that generates logical forms or new triples before retrieving relevant knowledge graph elements.
