The rationale extraction task identifies the court\u2019s accepting arguments from alleged arguments by plaintiffs and defendants, which is a novel task in the field. JTD is constructed based on annotated 3477 Japanese Civil Code judgments by 41 legal experts, resulting in 7978 instances with 59,697 of their alleged arguments from the involved parties. Our baseline experiments show the feasibility of the proposed two tasks, and our error analysis by legal experts identifies sources of errors and suggests future directions of the LJP research.<\/jats:p>","DOI":"10.1007\/s10506-024-09402-0","type":"journal-article","created":{"date-parts":[[2024,5,11]],"date-time":"2024-05-11T04:01:36Z","timestamp":1715400096000},"page":"783-807","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Japanese tort-case dataset for rationale-supported legal judgment prediction"],"prefix":"10.1007","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1963-958X","authenticated-orcid":false,"given":"Hiroaki","family":"Yamada","sequence":"first","affiliation":[]},{"given":"Takenobu","family":"Tokunaga","sequence":"additional","affiliation":[]},{"given":"Ryutaro","family":"Ohara","sequence":"additional","affiliation":[]},{"given":"Akira","family":"Tokutsu","sequence":"additional","affiliation":[]},{"given":"Keisuke","family":"Takeshita","sequence":"additional","affiliation":[]},{"given":"Mihoko","family":"Sumida","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,5,11]]},"reference":[{"key":"9402_CR1","doi-asserted-by":"publisher","unstructured":"Akiba T, Sano S, Yanase T, Ohta T, Koyama M (2019) Optuna: a next-generation hyperparameter optimization framework.
