Context Expansion: Smart Document Understanding

Revolutionary RAG Enhancement

Context Expansion transforms how Scrapalot understands and retrieves information from your documents, delivering 70% fewer hallucinations and 40% more complete answers through intelligent document structure awareness.

Traditional RAG systems work with isolated chunks of text, losing important context and relationships. Scrapalot's Context Expansion system solves this by understanding document structure and intelligently expanding context when needed.

How It Works

Context Expansion operates through intelligent document analysis and strategic context assembly:

The Problem With Traditional RAG

Traditional RAG systems break documents into isolated chunks, losing critical context:

Four Intelligent Strategies

Context Expansion provides four specialized strategies that work together:

1. Section-Based Expansion

Perfect for: Questions requiring complete procedural knowledge

2. AI-Powered Navigation

Perfect for: Complex questions requiring intelligent context decisions

3. Document Summary Enhancement

Perfect for: Providing rich background context

4. Structure-Aware Chunking

Perfect for: Technical documents with complex formatting

Real-World Impact

Before vs After Context Expansion

Quantified Improvements

Metric	Before	After	Improvement
Hallucination Rate	15-20%	<5%	70% reduction
Answer Completeness	50-60%	85%+	40% improvement
Citation Accuracy	30%	90%+	200% improvement
User Satisfaction	70%	95%+	25% improvement

Smart Context Selection

Context Expansion automatically chooses the optimal strategy based on your question type:

Configuration & Control

Context Expansion works automatically but gives you full control:

User Settings

• Enable/Disable: Toggle context expansion on or off
• Expansion Scope: Conservative, Medium, or Aggressive
• Strategy Preference: Let AI choose or select manually

Document-Level Control

• Processing Options: Enable context expansion during upload
• Hierarchy Detection: Automatic structure analysis
• Summary Generation: AI-powered document summaries

Performance & Efficiency

Context Expansion is designed for production use:

Getting Started

Context Expansion works automatically with your documents:

1. Upload Documents: Context analysis happens automatically
2. Ask Questions: Get complete, contextual answers
3. Review Citations: See exactly where information comes from
4. Adjust Settings: Fine-tune expansion behavior if needed

Automatic Intelligence

Context Expansion requires no setup or configuration. It automatically analyzes your documents and improves answer quality from your first question.

Best Practices

Document Preparation

• Clear Structure: Use proper headings (H1, H2, H3)
• Logical Organization: Group related information
• Consistent Formatting: Maintain formatting standards

Question Formulation

• Be Specific: "How do I configure SSL?" vs "Tell me about security"
• Use Context: "In the deployment section, how do I..."
• Ask Follow-ups: Build on previous answers for deeper understanding

Advanced Features

Multi-Document Context

Context Expansion can intelligently combine information across multiple related documents:

Continuous Learning

The system learns from usage patterns to improve context selection:

• Query Analysis: Understands common question patterns
• Success Metrics: Tracks answer completeness and accuracy
• Adaptive Behavior: Improves strategy selection over time
