Description

NLP is a key component in many data science systems that must understand or reason about text. David Talby, Alex Thomas, and Claudiu Branzan use the open source Spark NLP library to explore advanced NLP in Python. Spark NLP provides state-of-the-art accuracy, speed, and scalability for language understanding by delivering production-grade implementations of some of the most recent research in applied deep learning. It’s the most widely used NLP library in the enterprise today.

You’ll edit and extend a set of executable Python notebooks by implementing these common NLP tasks: named entity recognition, sentiment analysis, spell checking and correction, object character recognition (OCR), document classification, and multilingual and multidomain support. The discussion of each NLP task includes the latest advances in deep learning used to tackle it, including the prebuilt use of BERT embeddings within Spark NLP, using tuned embeddings, and “post-BERT” research results like XLNet, ERNIE, and roBERTa.

Spark NLP builds on the Apache Spark and TensorFlow ecosystems, and as such it’s the only open source NLP library that can natively scale to use any Spark cluster, as well as take advantage of the latest processors from Intel and NVIDIA. You’ll run the examples locally on your laptop, but David, Alex, and Claudiu explain and show a complete case study and benchmarks on how to scale an NLP pipeline for both training and inference.

Prerequisite knowledge

  • A working knowledge of Python, Jupyter notebooks, and basic machine learning
  • Familiarity with deep learning and NLP

Materials or downloads needed in advance

  • A laptop capable of running Docker with 8GB or more (You'll receive an email a week prior with instructions on how to pull and run the local Docker container that contains the library, all dependencies, example notebooks, and datasets.)

What you'll learn

  • Get hands-on experience with building NLP pipelines, both training and inference, for common NLP tasks, using Spark NLP in Python
