IR + QA system on Wikipedia articles
This repository holds code for the Information Retrieval part of our project work for NLP2020 class by Paolo Torroni @unibo.
We tackle the IR problem with a classic tf-idf approach and with a contrastive Bi-Encoder model based on ELECTRA.
An in depth description of the work can be found here: QA-IR-report.pdf.
