The JGU WEKA REST service provides an OpenRiskNet compliant REST interface to machine learning algorithms from the WEKA library. This web service is developed by the Institute of Computer Science at the Johannes Gutenberg University Mainz.

OpenRiskNet is funded by the European Commission GA 731075.

WEKA is developed by the Machine Learning Group at the University of Waikato.

Documentation, Issue Tracker and Code available at GitHub.

The JGU WEKA REST service is based on the Swagger-UI and JAX-RS frameworks. The API is in OpenAPI Specification ver. 3.0.1

To run a local environment for exploring the web service, execute the following:

mvn clean package jetty:run

This will run the Swagger-UI based REST API web service on a local Jetty instance which can then be viewed at the following URI:

http://0.0.0.0:8081

To use the web service for modelling, etc., refer to the documents Docker Image Deployment and Docker Development Environment.

POSTing a WEKA ARFF file to the web service and training a BayesNet based WEKA model using the curl command is done as follows:

curl -X POST -H "Content-Type: multipart/form-data" -H "Accept:text/x-arff" \
     -F "file=@/path/to/data/weather.nominal.arff;" -F "estimatorParams=0.5" \
     -F "searchAlgorithm=local.K2" -F "estimator=SimpleEstimator" \
     -F useADTree=0 -F searchParams='-P 1 -S BAYES' \
