Implementing the Information-State Update Approach to Dialogue Management in a Slightly Extended SCXML
Fredrik Kronlid, Torbjörn Lager · 2007
The W3C has selected Harel statecharts, under the name of SCXML, as the basis for future standards in the area of (mul-timodal) dialogue systems. The purpose of the present paper is to show that a moderately extended version of SCXML can be used to implement the well-known Information-State Update (ISU) approach to dialogue management. The paper also presents an experimental implementation of Extended SCXML, accessible from a user-friendly web-interface. 1
