This implementation is based on the cnn library for this software to function.

Building

First you need to download the cnn library and related libraries, and make them compiled, and then download the directory into the cnn

copy -r constituent_hierarchy cnn/

Add the directory into CMakeList.txt

cd cnn
vi CMakeList.txt
add_subdirectory(constituent_hierarchy)

Follow the cnn README to compile them

Preprocessing

You can get the constituent hierarchy by scripts/conhier_s.py for s-type constituent hierarchy and scripts/conhier_e.py for e-type constituent hierachy

scripts/conhier_s.py train.con > train.s
scripts/conhier_e.py train.con > train.e

Training

./s-hierarchy-trainer train.s dev.s

Decoding

./s-hierarchy-trainer train.s test.s

It will automatically generate the output file test.sOUT, which then can be used as extra features on the lookahead implementation of ZPar
