PDFMathTranslate: AI-Powered PDF Document Bilingual Translation with Layout Preservation

What is PDFMathTranslate?

PDFMathTranslate is an open-source project focused on full-text bilingual translation of PDF documents, with special attention to preserving mathematical formulas, charts, and complex layouts. It supports multiple translation services, including Google Translate, DeepL, Ollama, and OpenAI, and offers various usage methods such as command-line interface (CLI), graphical user interface (GUI), Docker containers, and Zotero plugins.

Main Features

• Layout Preservation: Translated documents retain the original formatting, including math formulas, charts, and references.

• Multilingual Support: Supports bidirectional translation between multiple languages to meet diverse user needs.

• Multiple Translation Engines: Integrates various translation services, allowing users to choose the most suitable one.

• Cross-Platform Availability: Provides CLI, GUI, Docker, and Zotero plugin options for flexible usage on different platforms.

• High-Quality Translation: Utilizes advanced AI technologies to ensure accurate translations of specialized terminology.

Technical Principles

• Optical Character Recognition (OCR): Extracts text content from PDF files.

• Formula Recognition and Conversion: Uses deep neural networks to identify mathematical formulas and convert them into LaTeX format.

• Layout Analysis and Reconstruction: Analyzes original document layout to ensure the translated document preserves formatting.

• Multilingual Translation Models: Integrates multiple translation engines using state-of-the-art NLP models for text translation.
