About the DataHour:

Natural Language Processing (NLP) is a hotbed of research in data science these days and one of the most common applications of NLP is sentiment analysis. From opinion polls to creating entire marketing strategies, this domain has completely reshaped the way businesses work, which is why this is an area every data scientist must be familiar with.

Let's code a Sentiment Analysis project from scratch using Python (100% hands-on) together in the live session. In this DataHour, Prashant will cover regular NLP tasks, e.g., data cleaning using regex, stopwords, stemming, lemmatization & finally visualizing the results. Furthermore we'll do feature extraction on textual data (Bag of Words models) followed by ML model building & evaluation (incl. hyperparam tuning using pipelines!)

P.S this is the Part 1 of a 3 sessions series. Stay tuned for the next part. 

Basic understanding of Python programming and strong interest in NLP.

P.S it is advised to attend DataHour: Text Pre-processing using NLTK and Python for a better understanding of this DataHour.
