Objective of thesis: Metaphor detection and interpretation is a part of natural language processing/natural language understanding task. In metaphor detection, as a first step a sentence is classified into either a metaphor or a literal. If a sentence is classified as metaphorical, the task is then to label the word (unigram) or a sequence of words (n-grams) in the sentence as a metaphor or a literal. The current state of the art algorithms use the context given in the sentence, i.e., if a word is out of context with respect to the rest of the sentence then it indicates this word as a metaphorical expression. For example, "The alligator’s teeth are like white daggers", meaning that the teeth of an alligator are white and pointed. Here the word "daggers" is used metaphorically and is completely different from the rest of the sentence.

On contrary to the above example, the identification of metaphors in the poetry corpus is much more difficult, because all the words contained in the sentence are comprised of metaphors, e.g.,

“Till it touched the top of heaven.”

The Complete Poetical Works of Henry Wadsworth Longfellow Following these lines, the objective of this thesis is to annotate a poetry corpus with the state of the art algorithm for metaphor detection and analyse its output and report the failing examples and the causes of the failures.
