Usage

Prerequisite: JRE (1.8 or later)

Run the following command to try out the Linear, Semi and Latent models described in the paper.

java -Xmx32g -Xms8g -jar ns.jar  -modelname OIBAMN6 -thread 4 -subpath default -outputscope true -num_iter 1000 -reg 0.1 -optimizer lbfgs -dataset cdsco -lang en -discrete true -discardintest false -syntax true -useperl true -outputsem2012 true -unipos true

java -Xmx32g -Xms8g -jar ns.jar  -modelname SEMIBOI2 -thread 4 -subpath default -outputscope true -num_iter 1000 -reg 0.1 -optimizer lbfgs -dataset cdsco -lang en -discrete true -discardintest false -syntax true -useperl true -outputsem2012 true -unipos true

java -Xmx32g -Xms8g -jar ns.jar  -modelname OIBAMNLatent6 -thread 4 -subpath default -outputscope true -num_iter 1000 -reg 0.1 -optimizer lbfgs -dataset cdsco -lang en -discrete true -discardintest false -syntax true -useperl true -outputsem2012 true -unipos true -latentmax 2

Or you can simply run

./exp_cdsco.sh

Please download the Bioscope and CNeSp dataset before trying out the additional experiments. Use the following scripts for running such additional experiments:

./exp_bioscope.sh

./exp_cnesp.sh

SourceCode

The source code is written in Java, which can be found under the "src" folder.

Note that it is a Maven project, therefore we recommend you to import this project as a Maven project in eclipse.
