   Hello everybody,   
      
   I'm an italian student of Computer Science and now I'm preparing an exam of   
   Human Computer Interaction. In practise, I should annote some dialogues with   
   an appropriate communicative act (such as Answer, Request-Info, Agreement   
   etc), and create a Hidden Markov in which the states are the user's moves   
   (Comm. Act) and the arcs are the system's moves (Comm. Act). Therefore, I   
   need a software that allows learning of HMM, that is to say a software that   
   creates the structure of the dialogue. May you help me suggesting me any   
   useful software for this purpose?   
      
   Thanks a lot!   
   Alessia
