The problem

Students could not get straight answers about programs and policy; the information was spread across hundreds of university pages.

What made it hard

An answer without a citation is worse than no answer, so every response has to name the page it came from.

Architecture

  1. 01Scrapy crawls and normalises university pages into a corpus
  2. 02ChromaDB stores embeddings; queries are expanded into variations
  3. 03Hybrid retrieval combines semantic and keyword search
  4. 04FastAPI serves answers with a confidence score and source link

Outcomes

  • Cited by Northeastern's 2026 Outstanding Master's Student Award for Community Impact
  • Faculty-sponsored and deployed for student use
  • 80,000+ pages indexed and searchable
