1. A method of reducing ambiguities present in electronically stored words, the method comprising: receiving a plurality of characters in electronic form, the received plurality of characters corresponding to a sequence of words and including an ambiguous word that has one or more characters whose value is substantially uncertain; comparing at least some of the words in the sequence to an ontology, the ontology defining a plurality of nodes, each node being associated with a word, and each node being connected to at least one other node by a link, each link being associated with a concept that relates the words associated with the nodes connected by the link in a predetermined context; and identifying nodes in the ontology that correspond to the ambiguous word based on the comparison.
