10. The method of claim 9 , wherein each identified node is scored as a function of the links that connect the node and any other nodes associated with words that correspond to other words in the sequence of words.
9. The method of claim 1 , wherein the operations further comprise: identifying nodes in the first ontology that correspond to the ambiguous word based on the comparison to the first ontology; comparing at least some of the words in the sequence to a second ontology, the second 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, wherein at least some of the nodes are associated with non-textual image information that identifies an enhancement to character-based text; identifying nodes in the second ontology that correspond to the ambiguous word based on the comparison to the second ontology; scoring each of the identified nodes from the first ontology and the second ontology, wherein the scoring is at least partially based upon non-textual image information that identifies an enhancement to character-based text and is associated with at least some of the identified nodes; and selecting a node having the highest score from among the identified nodes in the first ontology and the second ontology.
