CAEVO: Cascading EVent Ordering System

A TempEval-style system for extracting temporal entities (events and time expressions), and labeling the temporal relations between the temporal entities. More details can be found here:

CAEVO uses the WordNet dictionaries. The dictionary files can be downloaded from:

https://wordnetcode.princeton.edu/wn3.1.dict.tar.gz

You also need a jwnl_file_properties.xml file that points to the location of your downloaded dictionary. The dictionary and this file can be stored anywhere on your drive. CAEVO looks for an environment variable JWNL that should have the path to the xml file.

For convenience, you can also download and install the directories with the provided shell script (there is a sample jwnl_file_properties.xml file in src/test/resources):

./download-wordnet-dictionaries

mvn compile
mvn test
mvn install
