The Handbook of NLP with Gensim

By: Chris Kuo

Overview of this book

Navigating the terrain of NLP research and applying it practically can be a formidable task made easy with The Handbook of NLP with Gensim. This book demystifies NLP and equips you with hands-on strategies spanning healthcare, e-commerce, finance, and more to enable you to leverage Gensim in real-world scenarios. You’ll begin by exploring motives and techniques for extracting text information like bag-of-words, TF-IDF, and word embeddings. This book will then guide you on topic modeling using methods such as Latent Semantic Analysis (LSA) for dimensionality reduction and discovering latent semantic relationships in text data, Latent Dirichlet Allocation (LDA) for probabilistic topic modeling, and Ensemble LDA to enhance topic modeling stability and accuracy. Next, you’ll learn text summarization techniques with Word2Vec and Doc2Vec to build the modeling pipeline and optimize models using hyperparameters. As you get acquainted with practical applications in various industries, this book will inspire you to design innovative projects. Alongside topic modeling, you’ll also explore named entity handling and NER tools, modeling procedures, and tools for effective topic modeling applications. By the end of this book, you’ll have mastered the techniques essential to create applications with Gensim and integrate NLP into your business processes.

Summary

We reviewed a few selected real-world use cases in this chapter to demonstrate the breadth and depth of the techniques that we have learned about in this book. We trust this chapter has inspired you with new ideas, motivated you to invent new applications, and showed you how to apply the code examples that we have included in this book.

NLP keeps evolving at an unprecedented speed. ChatGPT, CPT-4, Llama 2.0, and so on were all developed in 2023. It is foreseeable that more and more generative AI models will emerge. With the knowledge in this book, you will be able to transition to generative NLP. This book helped you familiarize yourself with the fundamentals of NLP, including concepts such as tokenization, part-of-speech tagging, named entity recognition, syntactic parsing, LSA, LDA, and BERTopic. These techniques form the basis for your journey into generative NLP. Generative NLP heavily relies on neural networks. This book also presented the basics of neural network architectures...
