Noun Synonyms in WordNet
elasticsearch, synonym, wordnet
Solution
Given that the format of `wn_s.pl` is
s(112947045,1,'usance',n,1,0).
s(200001742,1,'breathe',v,1,25).
A very raw way of doing that would be to execute the following in your terminal to only take the lines from that file that have the ',n,' string.
grep ",n," wn_s.pl > wn_s_nouns_only.pl
The file `wn_s_nouns_only.pl` will only have the entries that are marked as nouns.
Problem
I want to use the `synonym` tokenfilter in Elasticsearch for an index. I downloaded the Prolog version of WordNet 3.0, and found the `wn_s.pl` file that Elasticsearch can understand. However, it seems that the file contains synonyms for all sorts of words and phrases, while I am really only interested in supporting synonyms for nouns. Is there a way to extract those type of entries?
