Concetti Chiave
提供十分かつ関連性のある証拠は、ファクトチェックシステムのパフォーマンス向上に貢献する可能性があります。
Sintesi
1. Introduction
- Fake news is a pressing issue, especially during conflicts like the Russia-Ukraine conflict.
- Traditional fact-checking systems follow a pipeline approach involving evidence retrieval and claim verification modules.
- The role of evidence in fact-checking is crucial.
2. Evidence Analysis
- Proposed method uses Large Language Models (LLMs) to automatically retrieve and summarize evidence from the Web.
- RU22Fact dataset created with 16K samples on the Russia-Ukraine conflict, including claims, optimized evidence, and explanations.
- Experimental results show the potential of optimized evidence in improving fact-checking performance.
3. Related Work
- Existing fact-checking datasets categorized into synthetic and real-world datasets.
- Different methods for evidence document retrieval discussed.
4. Dataset Construction
- RU22Fact dataset constructed with claims related to the Russia-Ukraine conflict in multiple languages.
- Data collection involved scraping claims from fact-checking websites and news release websites.
5. Fact-Checking System
- Framework includes Evidence Optimization, Claim Verification, and Explanation Generation components.
6. Experiment
Claim Verification
- Different text encoders used for claim verification experiments.
- Results show that optimized evidence performs better than claims alone or random evidence.
Explanation Generation
- Two conditional text generators used for explanation generation experiments.
- Automated evaluation using ROUGE and BLEU scores shows promising results.
7. Conclusion
- Proposed method of optimizing evidence shows potential in enhancing fact-checking systems.
8. Limitations
- Information leakage concerns when retrieving documents from the web.
- Limited coverage of low-resource languages in the dataset.
