Implementation of a Multimodal Dialog System Using Extended Markup Languages
Speech Technology Group, Microsoft Research,

In this paper, we describe an implementation of a plan-based
multimodal dialog system using the extensible markup language
(XML). The dialog manager receives semantic objects
representing the userís utterance at the end of each userís turn.
We define a semantic markup language (SML), based on XML,
to describe these semantic objects. Following the principles of
XML Schema, we define the schema of SML in another XML
called semantic definition language (SDL). In addition to
supporting many discourse and dialog features, SDL is also
designed to represent the domain knowledge via the application
schema and the hierarchy of the semantic objects. We show that,
with a thoughtful design in SDL, SML can be expressive enough
that the behavior of a dialog planner can be fully specified in the
extensible stylesheet language (XSL), a standardized language
with a logical programming model that is most popular for
implementing intelligent systems.
