This year, Jus Mundi<\/a>\u2019s data science team decided to participate at SemEval 2023 [1]<\/a>, more specifically on Task 6 \u2013 B, \u201cLegalEval: Understanding Legal Texts Legal Named Entity Recognition\u201d. The goal of this task was to create a Named Entity Recognition system capable of detecting 14 types of legal named entities, such as Claimant, Judge, Witness, and Organizations, in Indian judgments.<\/p>\n\n\n\n

What is Legal Named Entity Recognition?<\/strong><\/h2>\n\n\n\n

Named Entity recognition, also known as NER, is a Natural Language Processing (NLP) task, that relies on tagging a word, or a group of them, with semantic labels, such as Location, Person, and Organization [2]<\/a>. In the case of Legal NER, these entities can be those related to the parties, such as Claimant and Respondent, but also those more related to judgments, such as Judge, Lawyer, Witness, Provisions, and Statutes.<\/p>\n\n\n\n

About Jus Mundi\u2019s Participation<\/strong><\/h2>\n\n\n\n

Jus Mundi decided to participate in Task 6 – B using technologies that our team of Data Scientists has developed in-house to deal with similar problems within Jus Mundi data. Specifically, we built a Legal NER using machine learning, using an architecture called Frustratingly Easy Domain Adaptation [3]<\/a> [4]<\/a>. The goal of this architecture is to train a model where the knowledge between different collections of data is shared in order to create a robust NER system. We created this architecture using PyTorch, a well-known framework to create neural networks, and DeBERTa-V3, a language model trained by Microsoft and accessible through the HuggingFace platform. Moreover, Jus Mundi trained this model using the French super-calculator \u201cJean Zay\u201d, through our project allocation 2022-AD011012667R1<\/em>.<\/p>\n\n\n\n
