“The fixed format of PDFs frequently causes text streams to be physically broken across lines or split by images, making it challenging for conventional translation methods to restore logical continuity.”

Root Cause Analysis

Physical-layer segmentation recognition

O.Translator employs proprietary document parsing algorithms to accurately identify text blocks in PDFs that are physically segmented for layout purposes, such as content spanning columns or text wrapping around images.

Logical-layer sentence reassembly

The system uses sentence merging technology to reassemble physically divided fragments into logical long sentences suitable for LLM processing. After translation, it dynamically adjusts spacing based on the target language's length, ensuring zero displacement of graphics and charts.

Final Solution Summary

Comprehensive low-level analysis ensures that the visual presentation of the translation closely matches the original document.
