Hybrid retrieval RAG research
DOST-funded research on retrieval-augmented generation for Philippine education, using a hybrid keyword-and-vector retrieval architecture.
Context
General-purpose chatbots answer confidently but often without grounding. In education, answers need to trace back to approved sources.
Approach
A retrieval-augmented generation (RAG) system with hybrid retrieval, combining keyword and dense-vector search, with evaluation built in from the start.
Status
Ongoing, DOST-funded research.
