1. A hardware device for analyzing a document including a text-based visual representation, comprising: a correspondence information hardware storage device, wherein the correspondence information hardware storage device holds known representations of graphical images as text-based visual representations, wherein the graphical images depict portraits of physical objects, wherein the physical objects include one or more faces, and wherein the text-based visual representations are associated with information that each describe one of the physical objects, wherein each text-based visual representation includes one or more respective arrays of characters and symbols arranged to visually depict the physical object, a respective meaning of each of the characters and symbols in the one or more arrays being unrelated to the physical object; an identification hardware device for identifying a text-based visual representation within a document, the text-based visual representation including one or more facial expressions, wherein the identification hardware device matches the text-based visual representation within the document to one or more of the text-based visual representations stored in the correspondence information hardware storage device by determining a respective edit distance between the text-based visual representation within the document and each of the one or more text-based visual representations stored in the correspondence information hardware storage and comparing each respective edit distance to a threshold, wherein each respective edit distance is the minimum number of operations to transform the text-based visual representation within the document to the respective text-based visual representation in the correspondence information hardware storage device, and wherein a Levenshtein Distance method is used to calculate the minimum number of operations; and an editing hardware device, wherein the editing hardware device retrieves information from the correspondence information hardware storage device that is identified, by the identification hardware device, as describing a text-based visual representation component within the document, and wherein the editing hardware device adds the retrieved information to the document, and adds the retrieved information to the document as meta-information, wherein the meta-information includes an object type, a name for the physical object, an emotion, and a facial expression, and displays the text-based visual representation component within the document and information that describes the text-based visual representation on a display.
