Revolutionizing the Legal Industry with Spark, NLP and Azure Databricks
From zero to data science in a legal firm: how one of the world’s largest law firms is reshaping operations with advanced analytics. Clifford Chance LLP is one of the ten largest law firms in the world. With thousands of global clients their teams handle millions of legal documents every year.
The data science team will share their approach to building an agile data science lab from zero on top of Apache Spark, Azure Databricks and MLflow. They will deep dive into how they used deep learning for natural language processing in the classification of large documents using MLflow and Hyperopt for model comparison and hyperparameter optimization.
