Abstract
This dissertation presents a new lexical resource which is named as 'PolyWordNet'. The
PolyWordNet mimics the way how the senses of polysemy words and their corresponding
related words are organized in a human mind. A related word of a sense of a polysemy word in
a given context is a word that can disambiguate the meaning of the sense of the polysemy
word in that context. The rationale behind the organization of words in PolyWordNet is that
any simple sentence, which contains a polysemy word, also contains at least a related word (s).
A sense of a polysemy word and its related word(s) in a sentence, therefore, have a strong
semantic relation which can be used to disambiguate the sense of the polysemy word. Utilizing
this semantic relation, PolyWordNet organizes the senses of polysemy words based on their
corresponding related words. The organization of words in PolyWordNet is completely
different as compared to the existing other popular lexical resources such as dictionary and
WordNet. The words in a dictionary are organized based on the alphabetical order. Therefore,
the words that spell alike come together but the words with similar meaning get scattered in
the dictionary. In WordNet, the words with similar meaning are placed together based on the
synonymy set. The polysemy words are the big problems in Natural Language Processing
tasks since they create the ambiguity. No lexical databases deals with the organization of
words based on these polysemy words. Therefore, the PolyWordNet is developed. The words
in PolyWordNet are organized in such a way that the senses of polysemy words and their
corresponding related words come together and form clusters. The results obtained from 63
runs of experiments performed on 3,541 words and tested by 4,105 different test sentences
show the word organization of PolyWordNet is better for word sense disambiguation. These
results also indicate that the word organization of PolyWordNet is acceptable and valid with
reference to the popular lexical database- WordNet.
