Using the information state update approach as implemented in TrindiKit, I have developed
a theory of dialogue management (“Issue-based Dialogue Management” or IBDM)
and implemented it in a dialogue system, GoDiS (Larsson, 2002). GoDiS provides general
solutions to several pervasive problems and issues in dialogue, such as: establishing shared
understanding, user initiative, dealing with multiple conversational threads, information
sharing between threads, revising information, multimodal interaction, multilinguality,
plug-and-play of dialogue system applications, etc.). Providing general solutions to general
problems in dialogue means they are solved once and for all, and this in turn means that
new applications which use these general solutions can be developed quicker and cheaper.
There has never been a proper manual for GoDiS; the closest thing to a manual is Larsson
(2002) but this is unsuitable for at least two reasons: (1) It does not provide a comprehensive
overview of the system (nor is it intended to), and (2) it is not up-to-date. A proper manual
should allow a beginner to understand the basics of the underlying theoretical approach,
explain the implementation, and provide detailed information about how to implement
new GoDiS applications.
It is likely that the GoDiS system itself will be slightly modified in the course of writing
a manual, as rough solutions (“hacks”) must be replaced to enable a comprehensive
Completion of the GoDiS manual is expected to take 1 month.
