KorAP

Corpus Analysis Platform by the Leibniz Institute for the German Language
README.md

KorAP is a corpus analysis platform that is suitable for very large, multiply annotated corpora and complex search queries, independent of specific research questions.

The main instance of KorAP serves the German Reference Corpus DeReKo.

The platform consists of several components, which are published as separate repositories. It is mainly developed at the Leibniz Institute for German Language.

Run and test KorAP locally

Running your own KorAP is super easy. Just copy and paste this line:

curl https://raw.githubusercontent.com/KorAP/KorAP-Docker/master/compose.yaml | COMPOSE_PROFILES="example" INDEX='example-index' docker compose -p korap up

This will download the necessary images, start KorAP, and make the web UI available at http://localhost:64543/.

Prerequisite: docker (including the docker-compose-v2-plugin)
