Welcome to Cambridge
In order to test our dialog theory, we have developed a tourist information
system for Cambridge. You can test this out by using the web interface
which is below or by calling the To use the web interface, just click on the "Call CamInfo" button. When you are done, click hang up. Please use natural language and a headset, as this will improve performance. You can enquire information about bars, restaurants, hotels, colleges, etc. The system is adaptive to the change of your goals and can correct its own mistakes while the dialogue goes along. You can also try the web interface in a separate larger window: 1200x800. If you need help with using this demo, please consult the sections help and issues. To obtain further information about the system or help, email fj228@cam.ac.uk or ky219@cam.ac.uk. Please note that for research purposes all calls are recorded. In addition, use of a headset is recommend as it improves the quality of service.
HelpThe web interface is implemented as a Java Applet. As result, it is necessary to have Java runtime installed on the computer. The CamInfo web interface was been developed and tested with Java 1.6. It is not guaranteed that the applet will work on different versions of Java. As the applet is using SIP protocol to connect to the dialogue system, the used computer has to have opened ports 5061 and 4010. This means that if there is a firewall between the computer and the Internet then the firewall has to be set to allow incoming communication (both TCP and UDP) on ports 5061 and 4010. WindowsThe system should work automatically with Java runtime 1.6. Linux (CentOS)If you have problems running the Java Applet in Firefox under Linux, install the Java plugin into the Firefox plugin directory.
