A common way to fact-check them is to first split the text into atomic, self-contained claims, then retrieve evidence for each claim and predict a verdict. How well the text is split strongly affects the final checking accuracy. Earlier resources mostly had annotators review… 2. **[Constructing a Japanese Verdict Prediction Dataset for Fact-Checking of LLM-Generated Texts](https://md.research.elamur.ai/free/en/papers/masano-2026-constructing-japanese-verdict-prediction-dataset/)** *(2026)* Fact-checking pipelines for LLM output usually end with verdict prediction, in which a claim is compared against retrieved evidence. 3. **[Demystifying Mixed Outcomes of Self-Training: Pre-training Analyses on Non-Toy LLMs](https://md.research.elamur.ai/free/en/papers/nakamura-2026-demystifying-mixed-outcomes-self-training/)** *(2026)* Studies of self-training disagree. Some report that LLMs improve when retrained on their own outputs, while others report model collapse. The authors suspect the disagreement comes from different experimental setups: strong models with engineered pipelines on one side, and toy models with unconditional generation on… ## Co-authors here 10 co-authors with a page, the most papers together first. - [Daisuke Kawahara](https://md.research.elamur.ai/free/en/authors/daisuke-kawahara/) ×3 - [Atsushi Keyaki](https://md.research.elamur.ai/free/en/authors/atsushi-keyaki/) ×2 - [Hideyuki Tachibana](https://md.research.elamur.ai/free/en/authors/hideyuki-tachibana/) ×2 - [Kaito Horio](https://md.research.elamur.ai/free/en/authors/kaito-horio/) ×2 - [Kouta Nakayama](https://md.research.elamur.ai/free/en/authors/kouta-nakayama/) ×2 - [Miwa Masano](https://md.research.elamur.ai/free/en/authors/miwa-masano/) ×2 - [Rei Minamoto](https://md.research.elamur.ai/free/en/authors/rei-minamoto/) ×2 - [Ribeka Keyaki](https://md.research.elamur.ai/free/en/authors/ribeka-keyaki/) ×2 - [Chaoran Liu](https://md.research.elamur.ai/free/en/authors/chaoran-liu/) - [Shuhei Kurita](https://md.research.elamur.ai/free/en/authors/shuhei-kurita/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) - [Language Resources and Evaluation Conference (LREC)](https://md.research.elamur.ai/free/en/venues/lrec/): [LREC 2026](https://md.research.elamur.ai/free/en/venues/lrec/2026/) ## Cited by Papers of our library cite their works 1 time (of the 149,439 papers whose bibliographies we read); [1 citing paper with a page here →](https://md.research.elamur.ai/free/en/authors/hirokazu-kiyomaru/cited-by/).
