  • This paper describes the application of the PARADISE evaluation framework to the corpus of 662 human-computer dialogues collected in the June 2000 Darpa Communicator data collection. We describe results based on the standard logfile metrics as well as results based on additional qualitative metrics derived using the DATE dialogue act tagging scheme. We show that performance models derived via using the standard metrics can account for 37% of the variance in user satisfaction, and that the addition of DATE metrics improved the models by an absolute 5%. ...

  • Chapter 1 - Introduction. This chapter addresses four issues: data communications, networks, protocols and standards, and standards organizations. First, we give a broad definition of data communications. We then define networks as a highway on which data can travel. We also discuss different types of protocols and the difference between protocols and standards. Then, we give a brief review of the standards organizations that we refer to throughout the book. Finally, we discuss network models.
