As well as using WordNets for synonym look-up, we can use the BabelNet API to generate lists of hyponyms, cohyponyms and hypernyms.
The BabelNet look-up script can be started with the following command:
java -Xmx70g -cp tracer.jar eu.etrap.tracer.preprocessing.external.semantic.BabelNetTestMain ../lemma-list.txt EN >babelnet-queries.log
-Xmx70gdefines the memory to be used on the server; with a 70 gigabyte memory the BabelNet API look-up can take up to three days to compute.
lemma-list.txt(a better file name might be
lemma-babelnet.txt) is a modified version of TRACER's
lemma.txtfile containing only the base-form of every word in the text and its PoS tag (so, a two column file separated by a TAB). Place the
lemma-list.txtin the TRACER's
data/corpora/...directory and define its path in the command above.
babelnet-queries.logis the log.
The script crunches two parameters: the
lemma-list.txt and the language code (e.g.
EN if you are working with English texts,
DE if you are working with German texts, etc.). All generated files will be placed in the TRACER directory.
cat babelnet-queries.log | grep "PROCESSING WORD" | wc -l you see the total number of processed words out of the total number of base-forms in
