  • Patent number: 7587308
    Abstract: Systems, and associated apparatus, methods, or computer program products, may use ontologies to provide improved word recognition. The ontologies may be applied in word recognition processes to resolve ambiguities in language elements (e.g., words) where the values of some of the characters in the language elements are uncertain. Implementations of the method may use an ontology to resolve ambiguities in an input string of characters, for example. In some implementations, the input string may be received from a language conversion source such as, for example, an optical character recognition (OCR) device that generates a string of characters in electronic form from visible character images, or a voice recognition (VR) device that generates a string of characters in electronic form from speech input. Some implementations may process the generated character strings by using an ontology in combination with syntactic and/or grammatical analysis engines to further improve word recognition accuracy.
