COLIEE-2020 |Call for participation

Call for participation for the 7th Competition on Legal Information Extraction and Entailment (COLIEE-2020), to be held on 16 and 17 November 2020 in Yokohama, Japan. This event will include tasks on both statute law and case law.

Four tasks are included in the 2020 competition: 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 a fragment 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.

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 are required to submit a paper on their method and experimental results. At least one of the authors of an accepted paper has to register for JURISIN 2020 and present the paper on site at the special COLIEE 2020 session or on line if he/she cannot attend the session on site. The papers by the winners of each task in the competition will be further reviewed and considered for inclusion in the LNAI 2020 post-proceedings, so please write your papers with that in mind. In addition, we expect to raise some kind of cash prize for the winners in each category. These papers will be reviewed in the same way of usual submission to JURISIN 2020 and selected papers will be published in the LNAI post-proceedings.
