Natural Language Processing Fundamentals
Course Description
If NLP hasn't been your forte, Natural Language Processing Fundamentals will make sure you set off to a steady start. This comprehensive guide will show you how to effectively use Python libraries and NLP concepts to solve various problems.
You'll be introduced to natural language processing and its applications through examples and exercises. This will be followed by an introduction to the initial stages of solving a problem, which includes problem definition, getting text data, and preparing it for modeling. With exposure to concepts like advanced natural language processing algorithms and visualization techniques, you'll learn how to create applications that can extract information from unstructured data and present it as impactful visuals. Although you will continue to learn NLP-based techniques, the focus will gradually shift to developing useful applications. In these sections, you'll understand how to apply NLP techniques to answer questions as can be used in chatbots.
By the end of this course, you'll be able to accomplish a varied range of assignments ranging from identifying the most suitable type of NLP task for solving a problem to using a tool like spacy or gensim for performing sentiment analysis. The course will easily equip you with the knowledge you need to build applications that interpret human language.
Overview
This is a three-day course that starts with basics and goes on to explain various NLP tools and techniques that equip you with all that you need to solve common business problems for processing text.
Course Length
3 days
Scope
This course takes a hands-on approach to the practical aspects of using Python to build NLP applications. It contains multiple activities that use real-life business scenarios for you to practice and apply your new skills in a highly relevant context. Here is the list of course objectives:
- Learn about space and time complexities express them using big O notation
- Explore various classic sorting algorithms, such as merge and quick sort
- Understand the workings of basic (Lists, queues and stacks) and complex data structures (hash tables and binary trees)
- Gain an insight into various algorithm design paradigms (Greedy, Divide and Conquer and Dynamic programming)
- Discover string matching techniques
- Master graph representations and learn about different graph algorithms, such as cycle detection, traversal and shortest path
Target Audience
Natural Language Processing Fundamentals is designed for novice and mid-level data scientists and machine learning developers who want to gather and analyze text data to build an NLP-powered product. It'll help you to have prior experience of coding in Python using data types, writing functions, and importing libraries. Some experience with linguistics and probability is useful but not necessary.
