In MaxEnt, the values for the different parametersŵ are obtained by maximizing the log-likelihood of the training data T with respect to the model (Berger et al., 1996): Given our observations about the structure of dialogues in our corpus, we hypothesize that a dialogue is fundamentally sequential: first one person talks and then others react to them or ignore them, but the discourse links that do occur between speaker turns are reactive.
a turn can't be anaphorically and rhetorically dependent on a turn that comes after it.
