Architectural Design Document

Overview

Mexico asks US state attorneys general - This document outlines the design for a comprehensive article rewrite system that transforms source content into unique, well-formatted HTML while preserving factual accuracy and meeting all specified requirements.

System Architecture

1. Input Processing Module

- URL Extraction: Parse and validate source URLs - Content Ingestion: Load original article text, title, and metadata - Language Detection: Identify source language for preservation decisions

2. Content Analysis Engine

- Fact Extraction: Identify and catalog all factual elements: - Names (people, organizations, locations) - Dates and time periods - Numerical data (counts, statistics) - Direct quotes - Causal relationships - Sentence Structure Mapping: Analyze grammatical patterns for transformation opportunities

3. Rewrite Transformation Pipeline

- Semantic Preservation Layer: Ensure meaning remains intact while changing expression - Structural Reordering Module: - Paragraph sequence modification - Information hierarchy adjustment - Chronological vs. thematic organization options - Lexical Variation Engine: - Synonym substitution (context-aware) - Voice conversion (active/passive) - Clause restructuring - Phrase reordering

4. Length Expansion Strategy

- Contextual Elaboration: Add relevant background information - Logical Connections: Strengthen relationships between facts - Thematic Development: Expand on implications and significance - Verification: Ensure all additions are factually supported

5. HTML Formatting Module

- Tag Generation: Create proper semantic HTML structure - Quote Handling: Wrap direct quotes in `

` elements - Heading Hierarchy: Implement `

` and `

` appropriately - Validation: Ensure well-formed HTML output

6. Quality Assurance System

- Consecutive Word Check: Verify no 8+ word verbatim copies - Fact Verification: Cross-reference all extracted facts - Length Validation: Confirm minimum word count requirements - HTML Validation: Ensure proper tag nesting and closure

Implementation Notes

1. Modular Design: Each component can be independently tested and updated 2. Scalability: Architecture supports batch processing of multiple articles 3. Extensibility: New formatting options and language pairs can be added 4. Error Handling: Each module includes validation and fallback mechanisms

Architectural Decisions

1. Pipeline Architecture: Chosen for linear processing flow with clear input/output contracts 2. Separation of Concerns: Fact extraction, transformation, and formatting are decoupled 3. Validation at Each Stage: Ensures quality throughout the pipeline, not just at the end 4. Configurable Rules Engine: Allows customization of constraints (word count, consecutive words, etc.)

Data Flow Summary

1. Ingest → Source article and metadata 2. Analyze → Extract facts and structure 3. Transform → Rewrite with structural and lexical changes 4. Expand → Add context if needed for length requirements 5. Format → Apply HTML structure and quotes 6. Validate → Check all constraints 7. Output → Generate final HTML document

This architecture ensures consistent, high-quality article rewrites that meet all specified requirements while maintaining factual integrity and producing clean, semantic HTML output.
