Ontology of Graphemes for Latin Character Recognition

Abstract In this paper, we present a general description of an ontology, describing the different character of Latin language, which is semantically annotated by a domain expert. This ontology represents the typographical description of the analyzed and processed document, by a set of concepts where each concept, represents a grapheme of character and must be designated by a unique number denoting its position or its localization in the document. The relationship between, two graphemes is of spatial type; it represents the connectivity between graphemes in the document to facilitate the recognizing process of characters. Our ontology is generic and can support other languages by enriching it by new specific spatial relationships.
