Provides a webservice exposing Stanford Stanza as a webservice.
First clone the repository
git clone [email protected]:redlink-gmbh/stanza-server.git
Build the docker image
docker build -t stanza-server .
Run the server via docker
docker run -p 8080:8080 -v ~/stanza_resources/:/root/stanza_resources/ stanza-server
Note:
- the volume for
/root/stanza_resourcesprevents downloading models on every start
After this you can use the server under http://localhost:8080/process
To improve performance, stanza can use a Nvidia-CUDA on a GPU.
For CUDA-Support in docker, you have to install nvidia-docker2.
After that, start the container with gpu-support enabled:
docker run -p 8080:8080 --gpus all -v ~/stanza_resources/:/root/stanza_resources/ stanza-server
curl -X POST -H "content-type: application/json" \
'http://localhost:8080/process' \
-d '{"lang":"de","text":"Der Hauptsitz von Redlink ist in Salzburg"}'
and the response format:

- Stanza can load models for languages (e.g.
stanza.download('en')). I would like to have this configureable. For now it only downloads the German and English models are downloaded when it starts. - Dependency annotations are not supported yet
- The analysis pipeline is currently hardcoded. One could make this configurable
