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

In today's fast-paced digital environment, tracking sentiment shifts for mobile applications can significantly impact decision-making processes. With the increasing use of mobile devices, understanding the sentiment of users can help businesses adapt their strategies quickly. However, scraping sentiment data manually can become a tedious and error-prone task. This is where the Pulsebit API comes into play.

The Problem (DIY scraping pain)

Manually scraping sentiment data from various sources can be a nightmare. You often have to deal with:

• Inconsistent data formats
• Rate limits on scraping
• Legality and ethical concerns
• Continuous maintenance as websites change their structures

These challenges can lead to wasted time and unreliable data. Instead of spending hours writing scrapers and handling edge cases, it's better to leverage an API specifically designed for this purpose.

The Solution (Pulsebit API — one endpoint)

The Pulsebit API simplifies the process of tracking sentiment by providing a straightforward endpoint that aggregates sentiment data from multiple sources. With just one API call, you can retrieve sentiment scores, momentum, clusters, and confidence levels.

For instance, let's say you want to monitor the sentiment around mobile applications. The API provides the following data:

• Mobile Sentiment: 0.00
• Momentum: +1.30
• Clusters: 0
• Confidence: 0.87

The Code (Python GET /news_semantic)

To get started, you can use Python’s requests library to call the Pulsebit API. Below is an example of how to do this using the /news_semantic endpoint:

import requests

# Define your endpoint and parameters here
url = "https://api.pulsebit.co/news_semantic"
params = {
    "category": "mobile",
    "top_k": 5  # Adjust as necessary
}

# Make the API call
response = requests.get(url, params=params)

# Check if the request was successful
if response.status_code == 200:
    sentiment_data = response.json()
    print(sentiment_data)
else:
    print("Error fetching data:", response.status_code)

Make sure you replace the base URL and parameters according to your needs.

Reading the Response

The response from the API will typically look like this:

{
    "mobile_sentiment": 0.00,
    "momentum": 1.30,
    "clusters": 0,
    "confidence": 0.87
}

Here’s a breakdown of each field:

• mobile_sentiment: This indicates the overall sentiment score for mobile applications. A score of 0.00 suggests neutrality.
• momentum: A score of +1.30 indicates positive momentum, suggesting that sentiment is improving.
• clusters: The number of sentiment clusters detected. In this case, 0 means there are no strong sentiment groups.
• confidence: The confidence level of the sentiment score, which is 0.87 (or 87%), indicating a high level of trust in the data.

Three Use Cases

1. Algo Alert: You can set up an automated system that triggers alerts when sentiment changes beyond a certain threshold. For example, if the momentum drops below 0, you could get a notification to investigate further.

2. Slack Bot: Integrate the API with a Slack bot to provide real-time updates on mobile sentiment. This way, your team can stay informed without needing to manually check the data.

3. Dashboard: Create a dashboard that visualizes sentiment trends over time. Use libraries like Dash or Streamlit to build a user-friendly UI that updates with the latest sentiment data.
