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

Staying updated on the sentiment surrounding scientific topics can be challenging. Manually scraping data from various sources is tedious and error-prone. Luckily, the Pulsebit API provides a streamlined solution to track sentiment shifts in real-time, making it easier to stay informed.

The Problem (DIY Scraping Pain)

When trying to analyze sentiment in the science domain, many developers resort to DIY scraping. This approach often involves:

• Writing custom web scrapers
• Handling rate limits and CAPTCHAs
• Parsing various HTML structures
• Managing data consistency across sources

Not to mention, it's time-consuming and may require ongoing maintenance. If you're interested in sentiment analysis, you want to focus on insights, not data collection.

The Solution (Pulsebit API — One Endpoint)

Enter the Pulsebit API. This API simplifies the process of sentiment analysis with a single endpoint: /news_semantic. You can quickly retrieve sentiment scores, momentum, and other relevant metrics, allowing you to focus on what matters—understanding sentiment shifts.

The Code (Python GET /news_semantic)

Here's how you can use the Pulsebit API to get sentiment data for science:

import requests

def get_science_sentiment(api_key):
    url = "https://api.pulsebit.co/news_semantic"
    headers = {
        "Authorization": f"Bearer {api_key}",
        "Content-Type": "application/json"
    }
    params = {
        "topic": "science"
    }

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

    if response.status_code == 200:
        return response.json()
    else:
        raise Exception("Error fetching data from Pulsebit API")

api_key = "YOUR_API_KEY"
data = get_science_sentiment(api_key)
print(data)

Make sure to replace YOUR_API_KEY with your actual Pulsebit API key.

Reading the Response

The response from the /news_semantic endpoint contains several fields that provide insight into the current sentiment in the science domain. Here’s a breakdown of the fields based on the latest data:

• Science Sentiment: +0.40 — This indicates a moderately positive sentiment in the science domain.
• Momentum: +0.57 — This shows that the positive sentiment is gaining traction.
• Clusters: 0 — This indicates that there are currently no distinct clusters of sentiment; the data is relatively uniform.
• Confidence: 0.87 — This high confidence level suggests that the sentiment data is reliable.

Understanding these metrics can help you gauge how the public perceives scientific developments.

Three Use Cases

1. Algo Alert: You can set up a simple algorithm that triggers alerts based on sentiment changes. For example, if the sentiment drops below a certain threshold (say, +0.20), an alert can be sent to notify stakeholders.

2. Slack Bot: Integrate the Pulsebit API into a Slack bot that periodically checks sentiment and posts updates in your team’s channel. This way, your team can stay informed without actively searching for updates.

3. Dashboard: Create a dashboard to visualize sentiment trends over time. By regularly polling the API and storing the results, you can build a comprehensive view of how sentiment shifts in the science domain.
