Natural language processing(NLP) is a branch of artificial intelligence concerned with automated interpretation and generation of human language. From keyword search to Virtual Assistants, from spell checkers to language translators and from sentiment analysers to Chat bots, NLP finds its applications in most of our day to day applications. This workshop aims at delivering a basic Hands on tutorial to get started with NLP in Python. It commences with an introduction to NLP, discussion on various applications and a linguistic breakdown of Language (English).

By the end of this workshop you will be able to :

  • Install relevant packages such as nltk, gensim and pattern.
  • Applying text processing techniques such as Tokenization, Stemming, Lemmatization and Chunking.
  • Forming a Document Term Matrix using Bag of Words Model.
  • Building a simple Spam/Ham classifier using Bag of Words Model.
  • Generating Word Vectors using Gensim Word2Vec module.
  • Building a Sentiment Analyzer.

This workshop provides preliminary insight and a simple explanation to enthusiasts who wish to explore the field of Natural Language Processing. It enables you to talk to your computer!!
