Who were the clients ?

The project was a research collaboration with the University of Cambridge and Hitotsubashi University, Tokyo. Hitotsubashi is a leading research university in Japan, specialising in social science. UK Research and Innovation, the national funding agency of the UK, and the government of Japan helped fund the project.

What was the challenge?

Prof Dr Sumida Mihoko's research team analysed the decision-making of Japanese judges. Specifically, which circumstances courts rule themselves to be incompetent to make a judgement. They faced problems due to the lack of data and AI expertise. Also, a large amount of legal cases needed restructuring.

Why choose CourtCorrect?

CourtCorrect has rich legal AI datasets of structured legal cases along with skilled machine learning engineers. We'd already worked on international research projects by Cambridge and Uppsala University.

Solution: Adaptable AI models that structure legal data across languages

Using our database, we prepared a dataset of Japanese, American, and UK court cases. Our team created AI models capable of structuring this data. The AI could structure the key facts from a case with 80% accuracy in English and Japanese.

This included key details: legal arguments, evidence, and issues, judges and parties involved, and jurisdiction.

Result: Powering legal innovation in Japan

Our project kick-started long-neglected digitisation and innovation in the Japanese legal sector.

Our AI-structured dataset became the base for legal investigations by our partners. The work is published in the book 'Legal Innovation: Technology, the Legal Profession and Industrial Change'. More research projects using our Japanese dataset are in the pipeline.

Legal Innovation: Technology, the Legal Profession and Industrial Change,’ by Prof Dr Sumida Mihoko and Dr Felix Steffek. The scientific publication details the results of the first project to deploy AI in the legal sector in Japan. It includes a chapter authored by the CourtCorrect team.

CourtCorrect's CEO, Ludwig Bull, presented at the book launch and contributed a chapter to the publication. He will also join Hitotsubashi as an Assistant Professor and Visiting Researcher.

This project showcases CourtCorrect's AI's power and practicality. Case handlers around the world will extract key information from complex documents with ease, regardless of language or writing system..
