SimGRAG: Leveraging Similar Subgraphs for Knowledge Graphs Driven Retrieval-Augmented Generation (2025.findings-acl)
Copied to clipboard
| Challenge: | Recent advances in large language models (LLMs) have shown impressive versatility across various tasks. |
| Approach: | They propose a retrieval-augmented generation method that integrates LLMs with external knowledge sources to produce grounded outputs. |
| Outcome: | The proposed method outperforms state-of-the-art KG-driven methods in question answering and fact verification. |
Controlling Styles in Neural Machine Translation with Activation Prompt (2023.findings-acl)
Copied to clipboard
| Challenge: | Earlier studies on controlling styles in neural machine translation (NMT) have focused on regulating the level of formality, but they still encounter two major challenges. |
| Approach: | They propose a method to control the style of neural machine translation by retrieving prompts from stylized monolingual corpus. |
| Outcome: | The proposed method can control the style of translation and achieve remarkable performance. |
