Installing John Snow Labs NLP Libraries via AWS Marketplace: A Step-by-Step Tutorial

In this guide, we will navigate the process of subscribing to John Snow Labs NLP libraries through the AWS Marketplace and establishing a dedicated server for document processing. This comprehensive, step-by-step walkthrough will facilitate the prompt installation of the necessary libraries and the configuration of a server tailored to your requirements.

John Snow Labs presently offers two PAYG product bundles: Healthcare NLP here and Finance and Legal NLP here. The products include domain-specific packages of Python NLP libraries, that allow quick and easy text annotation with pre-trained DL models, rules, and prompts but also NLP model testing, training, and tuning. There is no limit on the number of documents, models, or pipelines that can be used with those subscriptions: the software is licensed on a per-usage basis.

Please select the bundle that aligns with your specific area of interest. While this guide primarily demonstrates the subscription process for the Healthcare NLP, the same methodology applies equally to the Finance and Legal NLP.
