vua-wsd-sem2015

System for the CLTL participation in SemEval2015 task 13: multilingual all-words sense disambiguation and entity linking.

##Installation

You will need just to clone the repository and run the instal.sh script, which will automatically download and install:

• ixa-pipe-pos: pos-tagger developed by the IXA group of the basque country (https://github.com/ixa-ehu/ixa-pipe-pos)
• It Makes Sense (IMS): wrapper around the IMS system for WSD to allow the use of NAF files (https://github.com/rubenIzquierdo/it_makes_sense_WSD)
• dbpedia_ner: wrapper around the dbpedia spotlight NER and NED for working with NAF files (https://github.com/rubenIzquierdo/dbpedia_ner)
• predominantsense: wrapper around predominant sense algorithm (https://bitbucket.org/MartenPostma/predominantsense)

The version of the IMS system only works with java 1.6, so make sure you are using that version, you can check with java -version. If you are using any other version, you will need to modify the file libs/it_makes_sense_WSD/ims/testPlain.sh and set the java command to the exact java1.6 binary.

Change:
java -mx2500m -cp $CLASSPATH sg.edu.
by:
/usr/lib/jvm/java-1.6.0-openjdk-amd64/bin/java -mx2500m -cp $CLASSPATH sg.edu.....

So basically these are the the only steps required:

git clone https://github.com/cltl/vua-wsd-sem2015
cd vua-wsd-sem2015
install.sh

##Usage

To run the whole system, you will need to call to the script run.sh. This script will automatically call to all the modules in our pipeline for processing the original SemEval2015 files that can be found at the folder SemEval-2015-task-13_original_data. It will create a new folder data_en_naf, where all the NAF files created will be stored. Different files with different suffixes represent intermediate results of the whole pipeline. After running run.sh, 'run_experiment.sh' will run the experiment. The output can be found in evaluation/stats.
