Natural Language Processing (Nlp) With Python And Nltk 2020

What you'll learn
Natural Language Processing using Python
Requirements
Basic programming skills in Python. Familiarity with numPy, Pandas and matplotlib would be helpful but not required.
Description
Natural Language Processing or NLP is a very popular field and has lots of applications in our daily life. From typing a message to auto-classification of mails as Spam or not-spam NLP is everywhere.NLP is a field concerned with the ability of a computer to understand, analyze, manipulate and potentially generate human language. In this course we study about NLP and use the NLP toolkit or NLTK in Python.The course contains following:Introduction to NLP and NLTKNLP PipelineReading raw dataCleaning and Pre-processingTokenizationVectorizationFeature EngineeringTraining ML Algorithm for Classifying Spam and non-spam messagesThis course would be very useful for Applied Machine Learning Scientists and Data Scientists who are working on NLP/NLU.
