Abstract
Modern semantic retrieval systems are typically built on Transformer embeddings and vector similarity search, which often result in near O(n²) computational behavior.
This talk introduces PipeOwl, an alternative encoding method that treats semantic representation as a structured scoring field over vocabulary, enabling O(n) query evaluation.
I will discuss the design motivations, implementation details, and benchmark results comparing PipeOwl with BM25, traditional embeddings, and FAISS-based retrieval systems.
The project is fully open source and includes multilingual models for Chinese and Japanese.
