Class RTGTranslator

java.lang.Object
org.apache.tika.language.translate.impl.AbstractTranslator
org.apache.tika.language.translate.impl.RTGTranslator
All Implemented Interfaces:
Translator

public class RTGTranslator extends AbstractTranslator

This translator is designed to work with a TCP-IP available RTG translation server, specifically the REST-based RTG server.

To get Docker image: https://hub.docker.com/repository/docker/tgowda/rtg-model
 {code
 # without GPU
   docker run --rm -i -p 6060:6060 tgowda/rtg-model:500toEng-v1
 # Or, with GPU device 0
   docker run --rm -i -p 6060:6060 --gpus '"device=0"' tgowda/rtg-model:500toEng-v1
 }
 

If you were to interact with the server via curl a request would look as follows

 {code
 curl --data "source=Comment allez-vous?" \
      --data "source=Bonne journée" \
      http://localhost:6060/translate
 }
 

RTG requires input to be pre-formatted into sentences, one per line, so this translation implementation takes care of that.
