TrindiKit 3.0: A toolkit for building and experimenting with dialogue move engines and information states

TRINDIKIT is a toolkit for building and experimenting with dialogue move engines and information states. We use the term information state to mean, roughly, the information stored internally by an agent, in this case a dialogue system. A dialogue move engine, or DME, updates the information state on the basis of observed dialogue moves and selects appropriate moves to be performed.

Apart from proposing general system architecture, the TRINDIKIT also specifies formats for defining information states, update rules, dialogue moves, and associated algorithms. It further provides a set of tools for experimenting with different formalizations of implementations of information states, rules, and algorithms. As from version 2.0, TRINDIKIT supports asynchronous (concurrent) control. To build a dialogue move engine, one needs to provide definitions of update rules, moves and algorithms, as well as the internal structure of the information state. One may also add inference engines, planners, plan recognisers, dialogue grammars, dialogue game automata etc. The current version of TrindiKit is 3.0 (released end December, 2002) and is downloadable from the TrindiKit web page (

More information on information states and related concepts and a link to the TrindiKit web page is available on the SIRIDUS web page
