Selecting What Matters: Semantic Compression-Guided Selective Pooling for Long-Context Embeddings

SCSP is a training-free framework that leverages semantic compression for informative token selection in long-context embedding and can be integrated into both zero-shot and fine-tuned models in a plug-and-play manner, consistently improving their performance.
