This page contains end-user oriented documentation for the 4.0 release of the Joshua decoder.
Follow this link to download Joshua, or do it from the command line:
wget -q http://cs.jhu.edu/~post/files/joshua-4.0.tgz
Next, unpack it, set the $JOSHUA environment variable, and compile everything:
tar xzf joshua-4.0.tgz cd joshua-4.0 # for bash export JOSHUA=$(pwd) echo "export JOSHUA=$JOSHUA" >> ~/.bashrc # for tcsh setenv JOSHUA `pwd` echo "setenv JOSHUA $JOSHUA" >> ~/.profile ant all
That's it.
If you just want to run the complete machine translation pipeline (beginning with data preparation, through alignment, hierarchical model building, tuning, testing, and reporting), we recommend you use our pipeline script. You might also be interested in Chris' old walkthrough.
For more detail on the decoder itself, including its command-line options, see the Joshua decoder page. You can also learn more about other steps of the Joshua MT pipeline, including grammar extraction with Thrax and Joshua's efficient grammar representation (new with version 4.0).
If you have problems or issues, you might find some help on our answers page or in the mailing list archives.
