1. A method of automated discourse analysis of interaction transcriptions, the method comprising; receiving, by at least one processor, a plurality of interaction transcriptions; for each respective interaction transcript of the plurality of interaction transcriptions: identifying, by the at least one processor, a plurality of meaning units within the respective interaction transcription; classifying, by the at least one processor, the plurality of meaning units into dialog acts, the dialog acts include at least the following categories: social, information, request, response and repetition, the repetition category being used to identify a repetition of a immediately previous dialog act when one party to a given interaction repeats a meaning unit previously spoken by another party to the given interaction; and identifying, by the at least one processor, durations between the dialog acts; selecting, by the at least one processor, a subset of the plurality of interaction transcriptions based on the durations; extracting, by the at least one processor, syntactic patterns from the selected subset; and outing, by the at least one processor, the extracted patterns as a visual presentation on a graphical display.
