11. A method comprising: receiving, by one or more processors, an image comprising text of a language; identifying a subimage within the image, the subimage corresponding to one or more of words and morphemes; identifying a set of character-sequences that represent candidate character-sequence representations of the subimage, wherein a character-sequence of the set is identified by traversing a path of the hierarchically organized data structure and accumulating a value for the character-sequence based on the scores on the path, wherein the value for the character-sequence in the set satisfies a predetermined threshold; using the candidate character-sequence representations of the subimage as hypotheses regarding the lexical identities of the subimage; constructing a portion of an electronic document corresponding to the received image comprising text using the hypotheses regarding the lexical identities of the subimages; and storing the constructed portion of the electronic document in one or more of the one or more electronic memories.

The method of claim 11 wherein the image comprising text is a digital encoding of a scanned or otherwise imaged block of text that is stored in one or more of the one or more electronic memories.
