Sentiment Analysis: Understanding the Emotion Behind Text

Actua's AI Series - Activity 9

In this activity, participants will learn about natural language understanding (NLU), a sub-area of natural language processing that focuses on how AI can comprehend the meaning of natural human language. Participants will learn about sentiment analysis, and how it can be used to detect emotion in text. They will then train and test their own sentiment analysis AI model.

If you’re accessing this activity directly, did you know there are eight other activities in this series up on our website? These activities also follow a space exploration narrative when done in order. It is recommended to complete the activities in order but they can also be done on their own.

If you find yourself unfamiliar with any of the AI concepts and terminology introduced in these activities, please refer to our AI Glossary. For more information about Artificial Intelligence and how to incorporate it into your classroom, we suggest exploring our AI Handbook.

Here we go:

You and your group mates are astronauts and scientists aboard the Actua Orbital Station. Unfortunately, your station just got bombarded by magnetic rays and your electronics have begun to shut down! The only one who can save you is the station’s AI, DANN. DANN stands for Dedicated Actua Neural Network, and it’s gone a little loopy. Brush up on your technical skills, learn about AI, and save yourself and your crewmates!

We’ve established DANN’s Code of Ethics in Ethics in AI: Don’t Let DANN Turn Evil” Mission Control has been working diligently to get DANN’s Language Processing Engine working. Now that it is, Mission Control has tasked you with restoring some of DANN’s ability to understand the content of the language that’s being used. DANN, needs to be able to identify and classify human emotions, so it knows when there’s an emergency situation. Help train DANN to re-learn how to detect emotions in words. Once that’s done, DANN will be fully back online! You’re about to save the whole space station!
