SEP — Semantic Encoding Protocol
Protocol Classification: Cognitive Enhancement
Protocol Version: 1.0.0
Integration Layer: RAG Enhancement
Governance Alignment: Five Laws Compliant
🎯 Protocol Purpose
The Semantic Encoding Protocol (SEP) provides lightweight, energy-efficient semantic embeddings for enhanced Retrieval-Augmented Generation (RAG) capabilities within the SIM-ONE Framework. SEP maintains architectural purity by keeping semantic encoding separate from the MVLM while dramatically improving the quality of memory retrieval, knowledge search, and contextual understanding.
SEP replaces basic mock embeddings and TF-IDF approaches with sophisticated transformer-based semantic representations, enabling the framework to understand meaning, context, and relationships between concepts rather than relying solely on keyword matching.
