●

●

Pun Detection as WSD
●
Assign senses to words, identify the words
with multiple valid possible meanings and
then maybe, just maybe, those are puns.
●
Context could be truly ambiguous or
under-specified, but many contexts have a
single assignment of senses.
●
SenseRelate Word Sense Disambiguation
●
Premise is to find the senses of words
that are most related to each other in a
context, then those senses should be
assigned to the words

Methods
●
Task 1 – WordNet::SenseRelate::AllWords w/
various measures & window sizes, if results
are different then there is a pun.
●
Task 2 – Last word that has changed senses
is the pun. Duluth 2 just chooses last word.
●
Task 3 – WordNet::SenseRelate::TargetWord
with local and global settings for different
window sizes to identify senses of punned
word. For heterographic puns :
●
Duluth 1 uses all WordNet words within 1
edit distance as candidates.
●
Duluth 2 uses DataMuse API to find
rhyming words, sound and spell alikes and
synonyms.
●
Future Work? Better finding of candidates
for heterographic puns and use of language
models in addition to relatedness measures.
