As an associated event of ICAIL 2023, we are happy to announce the 10th Competition on Legal Information Extraction and Entailment (COLIEE-2023), which will include tasks on both statute law and case law.
Four tasks are included in the 2023 edition: Tasks 1 and 2 are about case law, and tasks 3 and 4 are on statute law. Task 1 is a legal case retrieval task, and it involves reading a new case Q, and extracting supporting cases S1, S2…, Sn from the provided case law corpus, to support the decision for Q. Task 2 is the legal case entailment task, which involves the identification of one or more paragraphs from an existing case that entail the decision of a new case. As in previous COLIEE competitions, Task 3 is to consider a yes/no legal question Q and retrieve relevant statutes from a database of Japanese civil code statutes; Task 4 is to confirm entailment of a yes/no answer from the retrieved civil code statutes.
Further details can be found in the following URL: http://www.ualberta.ca/~rabelo/COLIEE2023/
The datasets for Task 1 and Task 2 are in English, and the datasets for Task 3 and Task 4 are available both in Japanese and English (translation from Japanese bar exams and civil code). You can choose any (or both) language datasets and any task for participation.
The intention is to build a community of practice regarding legal information processing and textual entailment, so that the adoption and adaptation of general methods from a variety of fields is considered, and that participants share their approaches, problems, and results.
Participants should clearly mention what dataset was used (for example, pretrained by Wikipedia dump data as of 2022xxxx, fine-tuned by …) for reproducibility purposes. Participants can use any external data, but it is assumed that they do not use the test dataset and/or something which could directly contain the correct answers of the test dataset, because this task is intended to be a pure textual entailment task.
Please submit a paper at:
https://easychair.org/conferences/?conf=coliee2023
Papers should not exceed 10 pages (inclusive of references) and should conform to the standards set out at the ICAIL 2023 webpage, section "Paper Submission" except copyright description (you just delete copyright description or you claim copyright of your paper by yourself).
Participants are required to submit a paper on their method and experimental results. At least one of the authors of an accepted paper has to present the paper at the COLIEE workshop of ICAIL 2023.
As post-proceedings, we plan to publish selected papers by another round reviews at a special issue at "The Review of Socionetwork Strategies"
