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

The Problem

If you've ever tried scraping film sentiment data, you know the pain. Websites are often riddled with anti-scraping measures, and even when you manage to gather data, it can be stale or not representative of current trends. You need a reliable, real-time source for sentiment analysis that can keep up with the rapid shifts in public opinion, especially in an industry as volatile as film. That's where the Pulsebit API comes in, offering a straightforward solution through a single endpoint, simplifying your life as a developer.

The Solution

Today, I want to share how the Pulsebit API can help you track sentiment shifts in the film industry with ease. The key is the GET /news_semantic endpoint, which provides a wealth of information in a concise manner. Here’s the good news: you can get actionable insights without wrestling with complex data gathering and processing.

The Code

Let’s dive into the implementation. Below is a simple Python code snippet using the Pulsebit API to fetch sentiment data about films:

import requests

url = "https://pulsebit.lojenterprise.com/api/v1/news_semantic"
headers = {
    "Authorization": "Bearer YOUR_API_KEY",  # Replace with your actual API key
}

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

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 API key from Pulsebit. This snippet makes a GET request to the API and prints the JSON response.

Reading the Response

Let’s break down the response you'll receive:

• TOPIC: This will indicate the subject of the sentiment analysis, in this case, "film".
• momentum_24h: Currently at +0.900, indicating a strong upward trend in sentiment over the last 24 hours.
• sentiment_score: A score of +0.350 suggests general positivity in film sentiment, which is noteworthy given its potential to influence box office performance.
• confidence: At 0.870, this high level of confidence indicates that the sentiment analysis is quite reliable.
• sentiment_index_0_100: A score of 67.5 falls in the positive range, suggesting a good reception for current films.
• direction: "rising", confirming the upward trend indicated by the momentum.
• semantic_clusters: Currently 0, suggesting that there are no significant clusters of related sentiment, which might indicate a broad but shallow interest.
• region: "us", meaning this data is specific to the United States.
• semantic_similarity_avg: A low average of 0.240 indicates that while sentiment towards films is rising, the topics being discussed are quite diverse.

Three Use Cases

Now that you have access to real-time sentiment data, what can you do with it?

1. Algo Alert: Create an alert system that triggers when the sentiment score exceeds a certain threshold. For instance, if the sentiment score rises above +0.500, it could indicate a potential hit movie, prompting you to act quickly.

2. Slack Bot: Integrate this data into a Slack bot that informs your team whenever there’s a significant sentiment shift. You can set it up to notify whenever the momentum exceeds +0.750, keeping everyone in the loop.

3. Dashboard: Build a dashboard that visualizes sentiment trends over time. Use libraries like Matplotlib or Plotly in Python to create graphs that display how sentiment scores fluctuate, helping you make informed decisions.
