ABSTRACT:
A method is disclosed for detecting topical changes and topic identification in texts in real time using likelihood ratio based methods. In accordance with the method, topic identification is achieved by evaluating text probabilities under each topic, and then selecting a new topic when one of those probabilities becomes significantly larger than the others. The method is usable to improve real time machine translation.
