To build a runnable jar just run "ant" in the source code root folder, make sure to not move the jar it requires the files from resources to run.

The application is controlled throught a command line interface:

java -Xmx2G -jar gateExtractor.jar -i <inputpath> [-t] [-r <outputpath>] [-e]

The first parameter -i is mandatory and provides the path to the corpus.

The -t (training) parameter starts the training mode, this has to be done atleast once with the testing corpus for the actual application to run.

The -r (run) parameter applies the learned rules on the corpus specified using the -i option. The outputpath is a directory where the results will be saved (HTML files).

The -e (evaluate) paramter does a k-fold cross validation using k=4.

Only one of the three modes (training, run, evaluation) can be selected at a time.

Depending on the performance of your system (number of cpus, cpu power) training and especially evaluation can take a long time.

Typical use would be:

#####Training:

java -Xmx2G -jar gateExtractor.jar -i trainingCorpus/ -t

#####Evaluating:

java -Xmx2G -jar gateExtractor.jar -i trainingCorpus/ -e

#####Running on some documents:

java -Xmx2G -jar gateExtractor.jar -i documents/ -r outputFolder/
