| Summary: | "The original vision of the Communicator systems included the ability of a user, during one ten-minute session, to plan a three leg trip, with the three flights/legs on three different days, with rental car and hotel in each of the two "away" cities, plus dictating/sending a voice-mail message. The actual research that led to the data collections in 2000 and 2001 explored ways to construct better spoken-dialogue systems, with which users interact via speech-alone to perform relatively complex tasks such as travel planning. During 2000 and 2001 two large data sets were collected, in which users used the Communicator systems built by the research groups to do travel planning. The researchers improved their systems intensively during the ten months between the two data collections."
