π Live Demo: Experience the platform in action at basilsuhail.com/news | Intelligence Dashboard: basilsuhail.com/market-intelligence
Imagine having a personal Bloomberg Terminal that processes 100+ news sources daily, uses machine learning to understand sentiment, and delivers actionable intelligenceβall running automatically in the background. That's exactly what this platform does.
This isn't just a news aggregator. It's a full-stack intelligence pipeline that:
- β Collects news from NewsAPI, RSS feeds, and GDELT (global events database)
- β Analyzes sentiment using BERT models (~90% accuracy on financial news)
- β Identifies named entities, calculates impact scores, and tags geopolitical risks
- β Clusters similar stories using semantic embeddings
- β Generates AI-powered executive briefings using Google Gemini
- β Backtests predictions against actual market data to validate accuracy
The platform is currently running on my portfolio website. You can explore:
π± News Feed
A clean, modern interface showing enriched news articles with:
- Sentiment scores (positive/neutral/negative)
- Entity extraction (companies, people, locations mentioned)
- Impact ratings (0-10 scale for importance)
- Source credibility indicators
A Bloomberg Terminal-inspired analytics dashboard featuring:
- Real-time Geopolitical Risk Index (GPR) - measures global tension based on news sentiment
- Sentiment distribution charts - visualize market mood across topics
- Entity sentiment timelines - track how sentiment evolves for specific companies/people
- Hindsight Validator - see how past sentiment predictions correlated with market movements
- Trending topics with volume anomaly detection
- Narrative threading - follow developing stories across multiple days
Most AI news platforms send every article to expensive LLM APIs. This project takes a smarter approach:
- Use offline ML models (BERT, NER, TF-IDF) for the heavy lifting
- Only use LLMs (Gemini) for high-value synthesis tasks
- Result: 80% cost savings + faster processing
What: Collect news from multiple sources
How:
- NewsAPI: Breaking news from 100+ publications
- RSS Feeds: Direct feeds from Reuters, Bloomberg, CNN, BBC
- GDELT: Global events database with real-time conflict tracking
Output: ~500-1000 articles per day (deduplicated)
What: Transform raw text into structured intelligence
How:
- Model:
Xenova/distilbert-base-uncased-finetuned-sst-2-english - Accuracy: ~90% on financial news
- Output: Sentiment score (-1 to +1), confidence level
- Library:
compromise(JavaScript NLP) - Extracts: Companies, people, locations, organizations
- Example: "Apple CEO Tim Cook announces new iPhone" β Entities: [Apple, Tim Cook, iPhone]
Calculates importance using:
ImpactScore = (0.4 Γ |Sentiment|) + (0.3 Γ ClusterSize) + (0.2 Γ SourceWeight) + (0.1 Γ Recency)
- Sentiment: How strongly positive/negative
- ClusterSize: How many sources cover this story
- SourceWeight: Reuters = 1.0, BlogSpot = 0.3
- Recency: Time decay factor
Tags articles with risk keywords and categories:
- Military keywords: "airstrike", "sanctions", "troops" β High Risk
- Diplomatic keywords: "treaty", "summit", "agreement" β Medium Risk
- Economic keywords: "recession", "inflation", "crisis" β Variable Risk
Output: Articles enriched with sentiment, entities, scores, and risk tags
What: Group similar articles into coherent narratives
How:
- Model:
all-MiniLM-L6-v2(sentence transformers) - Method: Convert articles to 384-dimensional vectors, cluster with K-means
- Fallback: TF-IDF + cosine similarity if embeddings fail
Connects clusters across days to track developing stories:
"Tech Layoffs" cluster (Feb 14) β "Tech Layoffs" cluster (Feb 15) β "Tech Hiring Freeze" cluster (Feb 16)
- Detects escalation (sentiment deteriorating)
- Identifies resolution (topic fading or sentiment improving)
Output: ~20-50 story clusters per day with multi-day threads
What: Generate human-readable insights using AI
How:
- Model: Gemini 1.5 Flash
- API Key Rotation: 6 keys in a pool to avoid rate limits
- Smart Caching: Hash-based deduplication prevents re-processing identical clusters
- Idempotent Processing: Same input = same output (cached)
Produces concise summaries like:
"Global tensions rising as military activity increases in Eastern Europe. Tech sector sentiment remains negative amid continued layoffs. Energy prices spiking due to supply chain disruptions."
Output: Daily briefing + per-cluster summaries
Purpose: Validate that sentiment predictions actually correlate with market movements
How it works:
- Fetch historical sentiment scores for a company (e.g., "Apple")
- Fetch actual stock returns for the same period (via Finnhub API)
- Calculate correlation between sentiment and returns
- Visualize on scatter plot
Example Output:
Apple (AAPL)
Correlation: +0.67 (moderate positive)
Interpretation: Positive news sentiment preceded 67% of positive returns
Purpose: Quantify global uncertainty using news sentiment
Formula:
GPR = Ξ£ (FearKeywordCount Γ CategoryWeight Γ SourceWeight) / TotalArticles Γ 100
Fear Keyword Dictionary (200+ phrases):
- Conflict: war, invasion, bombing, casualties β Weight: 1.0
- Economic: recession, collapse, crisis, default β Weight: 0.8
- Political: coup, protest, riot, sanctions β Weight: 0.7
Calibration:
- 20-40: Low risk (normal news cycle)
- 40-60: Moderate risk (emerging concerns)
- 60-80: High risk (multiple crises)
- 80-100: Extreme risk (major global event)
Purpose: Alert when a topic suddenly surges in coverage
Method: Z-score calculation
Z = (CurrentVolume - MeanVolume) / StdDeviation
- Z > 2: Unusual spike (alert worthy)
- Z > 3: Major spike (breaking news)
Use Case: Detect coordinated media campaigns, emerging crises, or PR blitzes
Purpose: Evaluate story trustworthiness
Logic:
- 1 source = Low confidence (could be exclusive or unverified)
- 2-3 sources = Medium confidence (likely true)
- 4+ sources = High confidence (confirmed by multiple outlets)

I built this platform to demonstrate that sophisticated financial intelligence doesn't require expensive enterprise tools. With the right architecture:
- β Local ML models can rival commercial sentiment APIs
- β Open-source NLP libraries can extract meaningful entities
- β Smart caching makes LLM costs negligible
- β Real-time intelligence is accessible to individual developers
This is what modern financial tech should look like: fast, cost-effective, and transparent.
