A proverb is worth a thousand words: learning to associate images with proverbs

AbstractWe describe a system that can associate images with English proverbs. We start from a corpus of proverbs, harvest related images from the web and use this data to train two variants of a convolutional neural network. We then collect a small set of annotations, and use these to combine the outputs of the two networks into a single prediction for each input image. We carry out feature selection experiments on a set of features derived from the images and from the predicted proverbs, and demonstrate that the metaphoricity of the proverbs plays a significant role in classification accuracy. An empirical evaluation with human raters confirms the system's ability to abstract from the raw bits in the images and to learn meaningful, non-trivial associations.
