COLIEE 2026

by National Institute of Informatics

COLIEE 2026 is the 16th edition of the Competition on Legal Information Extraction and Entailment, an annual event that brings together researchers and practitioners to advance the field of legal information processing. Organized by the National Institute of Informatics (NII) in Japan, the competition focuses on tasks such as legal case retrieval, statute law retrieval, and legal judgment prediction, aiming to improve the efficiency and accuracy of legal information systems.

The 2026 competition featured five main tasks: Legal Case Retrieval, Legal Case Entailment, Statute Law Retrieval and Entailment, Legal Textual Entailment, and a Pilot Task on Legal Judgment Prediction. Participants developed and evaluated models to address these challenges, contributing to the ongoing development of legal AI applications. Notably, the NOWJ team achieved first place in Task 4 (Statute Law Retrieval and Entailment) with a cross-architecture ensemble model, demonstrating the effectiveness of combining different model architectures for legal information processing.

While specific details about networking opportunities, expo halls, or notable speakers for COLIEE 2026 are not readily available, the event provided a platform for collaboration and knowledge sharing among experts in the field. Attendees had the opportunity to engage with cutting-edge research and discuss advancements in legal AI technologies.

Researchers, data scientists, and legal professionals interested in the intersection of law and artificial intelligence would find COLIEE 2026 particularly beneficial. The competition offers insights into the latest methodologies and challenges in legal information processing, fostering innovation and improvement in legal AI applications.
