We explore what names people use to describe visual concepts and why these names are chosen. Choosing object names has been a topic of interest in cognitive psychology, but a systematic, data-driven approach for naming at the scale of thousands of objects does not yet exist. First, we find that visual context has interpretable effects on visual naming, by analysing the MSCOCO dataset that has manually annotated objects and captions containing the natural language names for the object. We show that taking into account other objects as context helps improve the prediction of object names. We then analyse the naming patterns on a large dataset from Flickr, using automatically detected concepts. Preliminary results indicate that naming patterns can be identified on a large scale, but contrary to the conventional wisdom in cognitive psychology, are not dominated by genus for animals. We further validate the automatic method with a pilot Amazon Mechanical Turk naming experiment, and expl...
