| <p> |
| Joshua is an open-source statistical machine translation decoder for |
| hierarchical and syntax-based machine translation, written in Java. |
| It is developed by <a href="http://www.cs.jhu.edu/~ccb/">Chris |
| Callison-Burch</a>'s research group at |
| the <a href="http://clsp.jhu.edu">Center for Language and Speech |
| Processing</a> and the <a href="http://web.jhu.edu/hltcoe">Human |
| Language Technology Center of Excellence</a> at Johns Hopkins |
| University. |

| <a name="usage"/> |
| <h3>Usage</h3> |
| |
| <p> |
| Check out our <a href="4.0/index.html">large collection of user documentation</a> for |
| information on downloading and setup, a quick start guide, detailed information on |
| different Joshua components, common problems, and more. |
| </p> |
| |
| <p> |
| The easiest way to use Joshua is to use |
| <a href="https://github.com/joshua-decoder/joshua/wiki/Joshua-Pipeline">the |
| pipeline script</a> which is included with the source code. This |
| script supports multiple use cases; see the documentation for more |
| information. |
| For more detail, Chris Callison-Burch |
| describes <a href="http://www.cs.jhu.edu/~ccb/joshua/">how to manually |
| run the steps of the machine translation pipeline</a>. |
| (This information is a bit outdated and much of it is |
| automated by the pipeline, but the broad steps still apply). |
