Handbook-QA

Handbook-QA is the result of a Final Year Project at The University of Manchester. It makes use of the Haystack Python Library, Flask and React to provide an interface to search through documents to provide an answer using Natural Language Processing based Question Answering.

This project makes use of a Dense Passage Retriever and FAISS for Question Answering.

Different Evaluations can be found in the Evaluation-Notebooks folder
