==================== CALL FOR PARTICIPATION ======================
Competition on Legal Information Extraction/Entailment (COLIEE) 2021,
in association with the International Conference on Artificial Intelligence and Law (ICAIL) 2021
http://www.ualberta.ca/~rabelo/COLIEE2021/
https://icail.lawgorithm.com.br
June 21-25, 2021, São Paulo, Brazil (Online Conference)

As an associated event of ICAIL 2021, we are happy to announce the 9th Competition on Legal Information Extraction and Entailment (COLIEE-2021), which will include tasks on both statute law and case law.

Four tasks are included in the 2021 edition: Tasks 1 and 2 are about case law, and tasks 3, 4 and 5(new task) 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. Task 5 is to answer a yes/no question without the retrieved civil code statues.

Further details can be found in the following URL: http://www.ualberta.ca/~rabelo/COLIEE2021/

The datasets for Task 1 and Task 2 are in English, and the datasets for Task 3, Task 4 and Task 5 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.

We require participants to submit a paper on their method and experimental results to ICAIL 2021 in accordance with the instructions specified at https://icail.lawgorithm.com.br and to present the paper at the COLIEE workshop in ICAIL 2021 (held online).

Accepted papers will be published at an EPiC Series in Computing. The papers authored by the competition winners will be included in the main ICAIL 2021 proceedings if COLIEE organizers admit the paper novelty after the review process.
