‘... like a needle in a haystack”: Annotation and Classification of Comparative Statements

AbstractWe present a clear distinction between the phenomena of comparisons and similes along with a fine-grained annotation guideline that facilitates the structural annotation and assessment of the two classes, with three major contributions: 1) a publicly available annotated data set of 100 comparative statements; 2) theoretically grounded annotation guidelines for human annotators; and 3) results of machine learning experiments to establish how the–often subtle–distinction between the two phenomena can be automated.
