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

The Problem

As a developer diving into climate sentiment analysis, you know the pain of scraping data from various sources. It’s a labor-intensive process littered with unreliable signals and inconsistent formats. You might spend hours parsing HTML, navigating CAPTCHA challenges, and dealing with rate limits, only to end up with a mess of unstructured data. It's time-consuming and often yields questionable results.

Instead of relying on outdated methods or scraping multiple sites, what if you could tap into a single, robust API that provides real-time sentiment analysis specifically tailored to climate topics?

The Solution

Enter the Pulsebit API. This powerful tool allows you to access sentiment data effortlessly with a straightforward endpoint. You can get detailed insights on climate sentiment without the hassle of DIY scraping, enabling you to focus on building applications that matter.

The Code

To get started with the Pulsebit API, you’ll primarily use the /news_semantic endpoint. Here’s a simple example of how to retrieve the sentiment data using Python and the requests library.

import requests

# Replace with your actual API key
API_KEY = 'your_api_key'
url = 'https://pulsebit.lojenterprise.com/api/news_semantic'

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

# Making the GET request
response = requests.get(url, params=params)

# Check if the request was successful
if response.status_code == 200:
    data = response.json()
    print(data)
else:
    print(f"Error: {response.status_code}")

Reading the Response

Once you call the API, you’ll receive a structured JSON response. Here’s a breakdown of the most relevant fields:

• sentiment_score: The average sentiment score for climate discussions. Currently, it's at +0.000, which indicates neutrality in sentiment.
• momentum_24h: This shows a positive change of +1.217 in sentiment momentum over the last 24 hours. This is noteworthy because it suggests a sudden uptick in positive discussions around climate issues.
• confidence: At 0.870, this indicates a high level of certainty in the sentiment analysis. The higher the value, the more reliable the sentiment score.
• semantic_clusters: There are 18 clusters of related discussions, indicating a diverse range of topics being discussed within the climate space.
• direction: The sentiment is currently rising, which is particularly interesting given the neutral sentiment score.
• region: The data is categorized as global, providing a comprehensive view of sentiment across various regions.
• semantic_similarity_avg: At 0.272, this measures the average similarity between the clustered discussions, suggesting a moderate correlation among topics.

Three Use Cases

1. Algo Alert: You can set up an alert system that triggers when the momentum shifts significantly. For example, if momentum crosses a threshold (say +1.5), you could initiate automated responses or interventions.

2. Slack Bot: Integrate the Pulsebit API with a Slack bot that pushes updates on climate sentiment directly to your team. This keeps everyone informed in real-time about shifts in public sentiment, allowing for agile responses in your projects.

3. Dashboard: Create a visualization dashboard using libraries like Dash or Streamlit. This dashboard could display real-time sentiment data, including momentum trends and topic clusters, giving you a comprehensive view of climate sentiment at a glance.
