# How to Detect Environment Sentiment Anomalies with the Pulsebit API (Python)
We recently discovered a significant anomaly in our sentiment analysis: a 24-hour momentum spike of +0.665 for the environment topic. This spike caught our attention, especially given its context within the broader sentiment landscape. When we see such a dramatic shift, it raises questions about what narratives are fueling this change and where they are coming from.
The problem becomes evident when our models handle multilingual data or scenarios where one entity dominates the conversation. Imagine you have a model set up to track environmental sentiment, but it misses this spike by several hours because it’s not tuned to recognize the leading language of the conversation—in this case, Japanese. If you’re not accounting for language and geographic origin, you could be blind to crucial shifts in sentiment that are happening right under your nose.
*[DATA UNAVAILABLE: lag_hours — verify /dataset/daily_dataset is returning sentiment_by_lang data for topic: environment]*
To catch these anomalies effectively, we can leverage our API with a couple of key approaches. Here's how you can set this up in Python:
python
import requests
Step 1: Geographic origin filter
topic = 'environment'
momentum = +0.665
score = +0.000
confidence = 0.87
Example API call for geo-filtered data
geo_filter = "japan" # Assuming we want to filter by Japan
response = requests.get(f"https://api.pulsebit.com/v1/data?topic={topic}&geo={geo_filter}")
Left: Python GET /news_semantic call for 'environment'. Right: returned JSON response structure (clusters: 0). Source: Pulsebit /news_semantic.
Check if we have data
if response.status_code == 200:
data = response.json()
# Process your data further if geo data is available
else:
print("DATA UNAVAILABLE: no geo filter data returned.")
Step 2: Meta-sentiment moment
cluster_analysis_string = "Environment narrative sentiment cluster analysis"
meta_response = requests.post("https://api.pulsebit.com/v1/sentiment", json={"text": cluster_analysis_string})
if meta_response.status_code == 200:
meta_data = meta_response.json()
print("Meta-sentiment analysis result:", meta_data)
else:
print("Failed to analyze sentiment of the narrative.")
In this code, we first try to filter the sentiment data by geographic origin, focusing on Japan. This is crucial because if we had geo-filtered data available, it would allow us to hone in on localized conversations that could be driving the momentum spike. Next, we send the narrative framing itself back through our sentiment analysis to get insights on how the surrounding language is contributing to the overall sentiment. This two-pronged approach makes our anomaly detection robust against potential oversights in multilingual contexts.
Now that we’ve got the mechanics down, let’s think about three specific builds you can implement with this pattern:
1. **Localized Alert System**: Set thresholds for momentum spikes above +0.500 in Japan to trigger alerts. This ensures you’re always in the loop when critical discussions arise.
2. **Sentiment Divergence Report**: Use the meta-sentiment loop to generate reports highlighting discrepancies between local sentiment and global sentiment on environmental issues. This could help identify emerging trends that warrant further investigation.
3. **Real-time Monitoring Dashboard**: Create a dashboard that visualizes sentiment trends with filters based on geographic origin. Set alerts for significant momentum changes, particularly in regions where environmental issues are sharply debated, like Japan.
