How to Detect Sports Sentiment Shifts with the Pulsebit API (Python)

In the world of sports analytics, understanding sentiment can be the difference between a good decision and a great one. Yet, the traditional method of scraping social media or news sites for sentiment analysis can be tedious, error-prone, and time-consuming. Today, I want to show you how to leverage the Pulsebit API to detect sentiment shifts effortlessly.

The Problem (DIY scraping pain)

Manually scraping data from various sources to gauge sports sentiment is not only a headache, but it can also lead to outdated or inaccurate information. You have to handle:

• Different data formats
• Rate limits
• Parsing errors
• Constantly changing website structures

This DIY approach often leads to frustration and wasted time. What if I told you there’s a more streamlined way to access sentiment data?

The Solution (Pulsebit API — one endpoint)

The Pulsebit API offers a simple endpoint that allows you to retrieve sentiment data for various topics, including sports, without the hassle of scraping. With a single API call, you can access up-to-date sentiment metrics, helping you make informed decisions quickly.

The endpoint we’ll focus on is GET /news_semantic, which provides insights into sentiment analysis and momentum.

The Code (Python GET /news_semantic with code blocks)

Below is a simple Python script that utilizes the requests library to fetch sentiment data from Pulsebit. Make sure to install the library if you haven’t already:

pip install requests

Here’s how to retrieve sports sentiment data:

import requests

def get_sports_sentiment():
    url = "https://api.pulsebit.co/news_semantic"
    params = {
        'topic': 'sports'
    }

    response = requests.get(url, params=params)

    if response.status_code == 200:
        return response.json()
    else:
        raise Exception(f"Error: {response.status_code}")

if __name__ == "__main__":
    sentiment_data = get_sports_sentiment()
    print(sentiment_data)

Reading the Response

When you call the API, you receive a JSON response containing several fields. Here’s a breakdown of each:

• sentiment: The overall sentiment score, which ranges from -1 (very negative) to +1 (very positive). In our example, it’s +0.00, indicating neutrality.
• momentum: This value shows the rate of change in sentiment. A positive value, such as +1.18, indicates growing positive sentiment.
• clusters: This indicates how many distinct sentiment clusters were detected. For example, 0 means no significant clusters were identified.
• confidence: This reflects the reliability of the sentiment score, with a range of 0 to 1. A confidence of 0.87 suggests high reliability.

Three Use Cases

1. Algo Alert: You can build an algorithm that triggers alerts based on sentiment shifts. For instance, if the sentiment moves from neutral to positive (e.g., crossing +0.50), you can set off a notification to take action.

2. Slack Bot: Integrate the API into a Slack bot that automatically posts daily sentiment updates for sports teams. This keeps your teams informed and engaged without manual intervention.

3. Dashboard: Create a dashboard to visualize sentiment trends over time. Use tools like Plotly or Matplotlib to plot the sentiment scores and momentum for different sports, providing a clear view of shifts in public perception.
