Text-Preserving Lossy Text Compression: A Study of Strategic Deletion and LLM Reconstruction

In three linesStudy of lossy semantic text compression where an encoder strategically deletes text parts and an LLM reconstructs original content. Benchmarks 6 deletion strategies (uniform, frequency, entropy, LP-optimized, hybrid) on BBC News. WordFreq provides best cost/performance ratio; semantic methods excel at moderate compression; QLoRA fine-tuning competes with Gemini 2.0 Flash.
