+ * RTG translation server, specifically the
+ * <a href="https://isi-nlp.github.io/rtg/#_rtg_serve";>
+ * REST-based RTG server</a>.</p>
+ * To get Docker image:
+ * https://hub.docker.com/repository/docker/tgowda/rtg-model <br/>
+ * <pre>
+ * {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
+ * }
+ * </pre>
+ *
+ * <p>If you were to interact with the server via curl a request
+ * would look as follows</p>
+ *
+ * <pre>
+ * {code
+ * curl --data "source=Comment allez-vous?" \
+ * --data "source=Bonne journée" \
+ * http://localhost:6060/translate
+ * }
+ * </pre>
+ *
+ * RTG requires input to be pre-formatted into sentences, one per line,
+ * so this translation implementation takes care of that.

> RTG Translator with many-to-eng translation
> -------------------------------------------
>
> Key: TIKA-3329
> URL: https://issues.apache.org/jira/browse/TIKA-3329
> Project: Tika
> Issue Type: Improvement
> Components: translation
> Reporter: Thamme Gowda
> Assignee: Thamme Gowda
> Priority: Major
>
> The existing translation services in tika-translate are either
> commercial/paid engines (e.g. Google, Microsoft etc ) or not state of the
> art (such as Joshua, Moses etc).
> Reader Translator Generator () is a neural machine translation toolkit
> [https://isi-nlp.github.io/rtg/]
> and has the implementation of Transformer NMT model (current state of the
> art).
> It also has massively multilingual pretrained NMT model ( many-to-English
> translation direction)
> [https://hub.docker.com/repository/docker/tgowda/rtg-model]
> in which about 500 source languages are represented, with atleast ~300 source
> languages have good enough quality (For a comparison Google translate has
> ~106 languages, and Microsoft has about 80 languages).
> This issue is for integrating RTG Translator into tika-translate
>
