A Question Answering (QA) system aims at satisfying users who are looking to answer a specific question in natural language.
It works like search engines, but with different result representations: a search engine returns a list of links to answering resources, while a QA system gives a direct answer to a question.
The information-retrieval process in QA systems is broken down into three stages: question processing, ranking, and answer extraction.
This is a semantic search engine powered by SentenceTransformers with a retrieval and reranking system on Wikipedia corous.
