Hi all,
I am trying to use the function getLCSbyDepth from the package
WordNet::Similarity::DepthFinder to get the depth from the root of the noun
taxonomy to the LCS of a pair of senses.
I observed that the program crashed with the word "tilde" as following code:
my $df = WordNet::Similarity::DepthFinder->new($wn);
my @LCSs=$df->getLCSbyDepth("tilde#n#1","tilde#n#1","n",'wps');
The error was: Can't use an undefined value as an ARRAY reference at
/home/roth/quangdo2/lib/perl5/site_perl/5.8.5/WordNet/Similarity/DepthFinder.pm
line 150, <GEN8> line 36.
By thinking that I made a mistake with my own code, I tried the similarity
metric WordNet::Similarity::wup to get the similarity score for the pair
("tilde","tilde"). The program crashed in the similar fashion as my code above.
Have you ever experienced with this problem? If you have any advice to overcome
this problem, please let me know.
I appreciate your help.
Thanks a lot.
Quang
