  • Automatic orthographic transformation of a text stream
    Patent number: 6490549
    Abstract: A method is given for automatically rewriting orthography of a stream of text words, for example, automatically and properly capitalizing words in the stream. If a word in the stream has an entry in an orthography rewrite lexicon, the word is automatically replaced with an orthographically rewritten form of the word from the orthography rewrite lexicon. In addition, selected words in the stream are compared to a plurality of features weighted by a maximum entropy-based algorithm, to automatically determine whether to rewrite orthography of any of the selected words.
