Haystack is an open source NLP framework by deepset to help you build production ready search systems or applications powered by various NLP tasks such as Question Answering. Haystack is designed to help you build systems that work intelligently over large document collections. It achieves this with the concept of Pipelines consisting of various Nodes such as a DocumentStore, a Retriever and a Reader.

This repository contains fully working applications that demonstrate how to use Haystack to implement common NLP use cases: some of these applications are available online and all of them can run locally.
