# BMAD Request Analysis System

## Overview

The Request Analysis System provides comprehensive natural language processing and context analysis capabilities to understand user requests and extract relevant information for intelligent persona routing.

## Core Analysis Components

###  Natural Language Processing Pipeline

#### Text Preprocessing
```python
def preprocess_request(request_text):
    """
    Comprehensive text preprocessing for request analysis
    """
    
    # Basic text cleaning
    cleaned_text = clean_text(request_text)
    
    # Tokenization with context preservation
    tokens = advanced_tokenize(cleaned_text)
    
    # Named Entity Recognition
    entities = extract_entities(tokens)
    
    # Part-of-speech tagging
    pos_tags = pos_tag(tokens)
    
    # Dependency parsing for relationship extraction
    dependencies = parse_dependencies(tokens)
    
    return {
        'cleaned_text': cleaned_text,
        'tokens': tokens,
        'entities': entities,
        'pos_tags': pos_tags,
        'dependencies': dependencies
    }

def extract_entities(tokens):
    """Extract domain-specific entities from request"""
    entity_patterns = {
