Context-Driven Index Trimming: A Data Quality Perspective to Enhancing Precision of RALMs

EMNLP 2024finding

Retrieval-Augmented Large Language Models(RALMs) have made significant strides in enhancing the accuracy of generated responses. However, existing research often overlooks the data quality issues within retrieval results, often caused by inaccurate existing vector-distance-based retrieval methods. W…

RTFE: A Recursive Temporal Fact Embedding Framework for Temporal Knowledge Graph Completion

NAACL 2021long

Static knowledge graph (SKG) embedding (SKGE) has been studied intensively in the past years. Recently, temporal knowledge graph (TKG) embedding (TKGE) has emerged. In this paper, we propose a Recursive Temporal Fact Embedding (RTFE) framework to transplant SKGE models to TKGs and to enhance the per…
