Introduction to Natural Language Processing

Natural Language Processing (NLP) is the art of extracting information from unstructured text. This course teaches you basics of NLP, Regular Expressions and Text Preprocessing.

Natural Language Processing is the art of extracting information from unstructured text. Learn basics of Natural Language Processing, Regular Expressions & text sentiment analysis using machine learning in this course.

Natural Language Processing (NLP) is basically how you can teach machines to understand human languages and extract meaning from text.

Language as a structured medium of communication is what separates us human beings from animals. We are surrounded by text data all the time sourced from books, emails, blogs, social media posts, news and more.

Natural Language Processing is expected to be worth 30 Billion USD by 2024 with the past few years seeing immense improvements in terms of how well it is solving industry problems at scale.

Natural Language Processing (NLP) today powers many key real-life industry applications, such as:

Language Translation
Dialog Systems / Chatbots
Sentiment Analysis
Text Summarizers
Speech Recognition
Autocorrect

This free course by Analytics Vidhya will guide you to take your first step into the world of natural language processing with Python and build your first sentiment analysis Model using machine learning. Begin your NLP learning journey today!

- Where to go from here?

This free course helps you take that first step in the world of Natural Langauge Processing with the following curated topics to help you get started.

Reading and working with text data using Python In this section you will learn how to import text data using python for further processing
Learn to use Regular Expressions to extract patterns from text Have you ever thought of how specific patterns such as email IDs are extracted from a long text. Regular Expressions or regex is the Python module that helps you manipulate text data and extract patterns.
Text preprocessing Text is essentially strings and in order for a machine to work with, it needs to be transformed to numbers which the machine can understand. Also, there are words that you want to clean up from a text such as commonly occuring stopwords such as a, the, has, would and so on
NLP Project on Sentiment Analysis In this module, you will solve a Sentiment Analysis Project to detect hate speech from text using Machine Learning.

Certificate of Completion

Upon successful completion of the course, you will be provided a certificate by Analytics Vidhya with lifetime validity.

Is it a good time to pursue Natural Language Processing?
A good time to start with NLP is now! With plethora of applications in several markets & industries, NLP has become a highly sought after skill all over the world.
What is the best language to learn for solving NLP tasks?
Natural Language Processing with Python is the way to go and it has been the most popular language in both industry and Academia. Python provides excellent ready made libraries such as NLTK, Spacy, CoreNLP, Gensim, Scikit-Learn & TextBlob which have excellent easy to use functions to work with text data. Deep Learning frameworks like PyTorch, Tensorflow and Keras which are all part of Python Ecosystem are the default choices for using Deep Learning in Natural Langauge Processing.
Do I need to have a PhD to build a career in NLP?
Applied NLP is something that can be mastered by someone with good knowledge of Python and a background in Engineering or quantitative field is a good to have but not a necessity. Natural Language Processing with Python is something that can be taught and learnt with dedicated effort and a good learning path.
