This document discusses using machine learning techniques to minimize duplicate questions on question and answer platforms. It proposes a system that uses a sequence-to-sequence model within a recurrent neural network to extract keywords from questions and find similar existing questions. When a new question is submitted, these keywords are used to search the database and suggest relevant, previously asked questions to the user. This aims to reduce redundancy and help users more efficiently find answers by navigating to similar existing questions. The system architecture includes user registration and authentication, an Express server backend, MongoDB database, and a machine learning model for keyword extraction and question matching.
