Methods and apparatus are disclosed for classifying the relative position of one or more text messages (including transcribed audio messages) in a related thread of text messages. One or more classifiers are applied to the text messages; and a classification of the text messages is obtained that indicates the relative position of the text messages in the thread. For example, a thread can include a root message, a leaf message and one or more inner messages, and the classification can indicate whether each text message is a root message, a leaf message or an inner message. The classifiers are trained on a set of training messages that have been previously classified to indicate a relative position of each training message in a corresponding thread. The classifiers employ one or more features that help to distinguish between root and non-root messages.
