Do you want to understand how we built the most accurate Twitter Sentiment Analysis model for the Italian language in istella.ai?

In this seminar, we will together build, step by step, a sentiment analysis application using Colab platform: https://colab.research.google.com

After an introduction to the most common techniques used for sentiment analysis and natural language processing (NLP), we will put our hands on exploring three main NLP approaches:

1. Lexicon-Based Approach: this part will focus on WordNet, Polyglot, and NLTK tools for sentiment analysis.

2. Document-Based Approach: this part will use standard machine learning techniques like Naïve Bayes, Support Vector Machines, etc.

3. Context-Based Approach: we will explore deeper semantics of words using deep learning methods like CNN and LSTM.
