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

The Problem

As developers, we often encounter the challenge of scraping news and sentiment data from various sources. This DIY approach can become a painful process—dealing with rate limits, parsing messy HTML, and ensuring the data is meaningful and actionable. Furthermore, keeping track of sentiment shifts over time can be a daunting task.

What if you could simplify this process? Instead of relying on cumbersome scraping methods, you could use a dedicated API that provides sentiment analysis out of the box. That’s where the Pulsebit API comes in.

The Solution

The Pulsebit API offers a streamlined way to access sentiment data with just one endpoint. With the /news_semantic endpoint, you can retrieve sentiment scores, momentum, and other useful metrics directly from the API. This can save you significant time and effort, allowing you to focus on building your application rather than wrangling data.

The Code

To get started, you’ll need to make a GET request to the /news_semantic endpoint. Here’s a simple Python script that demonstrates how to do this using the requests library:

import requests

# Define your API URL and parameters
url = "https://pulsebit.lojenterprise.com/api/news_semantic"
params = {
    'category': 'environment'
}

# Make 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}")

Make sure to replace the URL with the correct endpoint for your use case and include any necessary authentication headers if required.

Reading the Response

The response from the Pulsebit API will include several key fields. Here’s a breakdown of what each field means, using the current data provided:

• environment_sentiment: 0.00 - This score indicates the overall sentiment regarding the environment. A score of 0.00 suggests a neutral sentiment, meaning there are no significant positive or negative feelings at this moment.

• momentum: 1.40 - This value reflects the rate of change in sentiment. A positive momentum indicates increasing interest or concern, while a negative value would suggest a decline. In this case, +1.40 shows a slight increase in momentum.

• clusters: 0 - This field indicates the number of sentiment clusters detected. A value of 0 could mean that there is insufficient data to form distinct groups.

• confidence: 0.87 - This score represents the API’s confidence in the sentiment analysis. A confidence level of 0.87 is quite high, suggesting that the results are reliable.

Three Use Cases

1. Algo Alert: You could set up an algorithm that triggers alerts when certain thresholds of sentiment or momentum are crossed. For example, if the momentum exceeds +2.00, it might indicate a significant shift worth investigating.

2. Slack Bot: Integrate the API into a Slack bot to send daily updates on environment sentiment. This would keep your team informed in real-time without manual checking.

3. Dashboard: Create a dashboard that visualizes sentiment over time. You could plot sentiment scores against time and highlight periods of significant momentum changes, helping stakeholders understand trends at a glance.
