How to Detect Emotions using Python

Welcome to our comprehensive tutorial on integrating AI emotion detection using Python! Whether you're building a chatbot, analyzing customer feedback, or developing an interactive application, understanding human emotions from text is an essential skill.

In this tutorial, we’ll show you how to leverage powerful AI tools and pre-trained machine learning models in Python to identify emotions in text. By the end of this guide, you'll have a clear understanding of how to integrate emotion detection into your projects.

‍

What is Emotion Detection?

Emotion detection is the process of analyzing human emotions from inputs like text, speech, or facial expressions. Using AI and machine learning, it can identify emotions such as happiness, sadness, anger, and excitement, leading to more intuitive and responsive user experiences.

This technology is applied in areas like customer support, content personalization, and emotional engagement in apps. By understanding emotional cues, systems can respond more human-like, fostering stronger connections and boosting user engagement.

‍

Applications of Emotion Detection

• Customer Support: Emotion detection helps tailor responses in customer service, allowing for more empathetic and effective interactions.
• Personalized Content: Platforms can recommend content based on users' emotional reactions, enhancing engagement.
• Mental Health Monitoring: Emotion detection aids in identifying signs of stress or depression, providing early intervention opportunities.
• Market Research: Emotion detection analyzes consumer sentiment, offering valuable insights for refining marketing strategies.

How to Detect Emotions?

Set Up Your Eden AI Account

‍Create an Account: If you don't have an Eden AI account, you can sign up for a free one using this link. You can get your API key from the API Keys section, along with the free credits offered by Eden AI.

2. Access Text Technologies: After logging in, navigate to the text processing section of the platform.

3. Select Emotion Detection: Choose the Emotion Detection feature.

‍

Live Test Models on Eden AI

Eden AI provides the option to live test the emotion detection models directly on their platform. This can be helpful for understanding the models' accuracy and their ability to detect various emotions. It allows you to test different models and choose the one that fits your needs before you start integrating it into your project.

‍

Implementing Emotion Detection in Python

‍

Install Python's Requests Module: Before making API requests, you'll need to install the requests library if you haven't already. Open your terminal and run the following command:

pip install requests

The requests library makes it easy to send HTTP requests in Python and handle responses. To interact with the Eden AI API using Python, you'll send a POST request containing the necessary data (text to analyze, chosen providers, etc.) and the API key for authentication.

‍

Code Example

Here is a code example to implement emotion detection using Python and the Eden AI API:

import json
import requests

headers = {"Authorization": "Bearer YOUR_API_KEY"}

url = "https://api.edenai.run/v2/text/emotion_detection"
payload = {
    "providers": "nlpcloud,vernai",
    "text": "I am angry!",
}

response = requests.post(url, json=payload, headers=headers)

result = json.loads(response.text)
print(result["nlpcloud"]["items"])

‍

1. Headers: The "Authorization" header is used to pass the API key to the Eden AI API.
2. URL: The API endpoint for emotion detection.
3. Payload: The data you send in the request. Here, we pass the text "I am angry!" along with the providers (nlpcloud and vernai) you wish to use for emotion detection.
4. Request: The "requests.post()"function sends the POST request to the Eden AI API with the payload and headers.
5. Result: The response is parsed using "json.loads() to extract the relevant emotion detection data.

‍

Interpreting the Results:

The response will contain information about the detected emotions. Here's an example of the structure:

{
    "nlpcloud": {
        "items": [
            {
                "emotion": "anger",
                "score": 0.95
            }
        ]
    }
}
