There has been a widely held view that visual representations (e. g., photographs and illustrations) do not depict negation, for example, one that can be expressed by a sentence "the train is not coming".

In formal semantics, there are two well-developed semantic frameworks: event semantics, which treats verbs and adverbial modifiers using the notion of event, and degree semantics, which analyzes adjectives and comparatives using the notion of degree.
