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

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

To run KorAP with an example corpus, use the following command:

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

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