Emojis and emoticons can be extremely useful in capturing subliminal messages and moods within the social context of conversations. An almost perceived sentiment is captured with such simplicity can give added information to a document with actionable intent. However, they may be difficult to define in metadata translation unless each iconic derivation can be interpreted from their pictograph representations. And, as such most have a Unicode representation with a standard pixel grid size. These ideograms add much variety to text speak in reducing verbage but also adding valuable meaning. May be, even a semantic data could be incorporated over such emojis supported with such open sentiment dictionaries like sentiwordnet. They are portable as well as quite varied, available as plugins, website services, on desktops, and mobile phones. Symbols and signs have always held valuable cues in our society from traffic signs, health and safety, to various other domains. The semiotics of such symbols holds much value in understanding language pragmatics over the web to discern, relate, pattern recognize in their universality, and then to even catagorize with their specific distinctions. In general, such pictograph ideograms can be categorized into the level of abstractions they provide for an individual from quality of feeling, to reaction and relation, and for their explicit representations. Such interpretations can often be provided through philosophical logic influenced in part by their psychological and sociological implications for inference.
