SyntheT2C: Generating Synthetic Data for Fine-Tuning Large Language Models on the Text2Cypher Task (2025.coling-main)
Copied to clipboard
| Challenge: | Existing efforts to bolster LLMs’ proficiency in Cypher generation are hindered by the lack of annotated datasets of Query-Cypher pairs. |
| Approach: | They propose a method for constructing a synthetic Query-Cypher pair dataset using LLM prompting and template-filling. |
| Outcome: | The proposed method enhances the performance of LLMs on Text2Cypher task via SFT. |
Mix-of-Granularity: Optimize the Chunking Granularity for Retrieval-Augmented Generation (2025.coling-main)
Copied to clipboard
| Challenge: | Retrieval-augmented generation systems often use a fixed strategy to extract information from multiple sources. |
| Approach: | They propose a method that dynamically determines optimal granularity of a knowledge source based on input queries using a router. |
| Outcome: | The proposed method predicts optimal granularity levels and significantly improves performance in downstream tasks. |
