Sentiment Analysis with Deep Learning, Machine Learning or Lexicon Based
Do you want to know what your customers, users, contacts, or relatives really think? Find out by building your own sentiment analysis application.
In this workshop you will build a sentiment analysis application, step by step, using KNIME Analytics Platform. After an introduction to the most common techniques used for sentiment analysis and text mining, we will work in three groups, each one focusing on a different technique.
- Deep Learning: This group will work with the visual Keras deep learning integration available in KNIME (completely code free)
- Machine Learning: This group will use other machine learning techniques, based on native KNIME nodes
- Lexicon Based: This group will focus on a lexicon based approach for sentiment analysis
