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

Understanding how public sentiment shifts around climate issues is crucial for researchers, policymakers, and businesses alike. But harvesting this kind of data can be a tedious task, typically involving DIY scraping solutions that are brittle, time-consuming, and often inaccurate. Let’s explore how the Pulsebit API can simplify this process.

The Problem (DIY Scraping Pain)

When trying to analyze climate sentiment, many developers resort to web scraping, which often leads to various issues:

• Fragility: Websites change frequently, breaking your scraping code.
• Rate Limiting: Many sites have strict policies against scraping, leading to IP bans.
• Data Quality: Extracted data can be noisy and require extensive cleaning.

These challenges can consume valuable development time and resources. Luckily, there's a better way.

The Solution (Pulsebit API — One Endpoint)

The Pulsebit API provides a straightforward solution with its GET /news_semantic endpoint. This endpoint allows you to fetch sentiment data, including climate sentiment, with just a few lines of code. No scraping necessary.

The Code (Python GET /news_semantic)

Here’s how to get started with the Pulsebit API in Python using the requests library. Ensure you have it installed:

pip install requests

You can use the following code to fetch climate sentiment data.

import requests

# Define your API key and endpoint
API_KEY = 'your_api_key'
URL = 'https://api.pulsebit.co/news_semantic'

# Set up parameters for the request
params = {
    'topic': 'climate',
    'api_key': API_KEY
}

# Make the GET request
response = requests.get(URL, params=params)

# Check for a successful response
if response.status_code == 200:
    data = response.json()
    print(data)
else:
    print(f"Error: {response.status_code}, {response.text}")

Replace your_api_key with your actual Pulsebit API key. This will return a JSON object with the latest sentiment data.

Reading the Response

The JSON response from the Pulsebit API contains several fields that provide insights into climate sentiment:

{
    "climate_sentiment": 0.00,
    "momentum": 1.22,
    "clusters": 0,
    "confidence": 0.87
}

• climate_sentiment: This is a score representing the overall sentiment towards climate topics. In our case, it’s 0.00, indicating a neutral sentiment.
• momentum: This value (1.22) indicates the rate of change in sentiment. A positive number suggests increasing interest or concern.
• clusters: The number of distinct groups of related sentiments. Here, we have 0, which may indicate no significant clustering in the current data.
• confidence: At 0.87, this indicates a high level of confidence in the sentiment analysis.

Three Use Cases

1. Algorithmic Alerts: Set up an alert system that triggers when climate sentiment shifts significantly, allowing you to respond to potential market impacts or news events quickly.

2. Slack Bot: Create a Slack bot that posts daily updates on climate sentiment. This can keep your team informed and engaged with the latest developments.

3. Dashboard: Visualize climate sentiment trends over time using a dashboard. Tools like Dash or Streamlit can pull data from the API and provide real-time analytics.
