The eighth IJCAI workshop on ``Knowledge and Reasoning in Practical
Dialogue Systems'' will focus on challenges arising due to comprehension
difficulties in dialogue systems. These difficulties include speech
recognition errors and speech disfluencies in spoken dialogue systems,
syntax errors, out-of-grammar and out-of-vocabulary phenomena, rambling
discourse, as well as non-cooperative dialogues. Topics addressed in
the workshop include, but are not limited to, the following:

- Approaches for identifying different types of comprehension
difficulties, ranging from mis-hearing to uncooperative
interlocutors. In particular, how does a dialogue system determine
how well it has understood an utterance?

- Approaches for addressing these difficulties, e.g., correcting likely
hearing problems, learning unknown words, and asking clarification

- How different types of comprehension difficulties should be addressed
in different parts of a dialogue system, e.g., interpretation,
dialogue strategy, and response generation.

- Robustness when faced with unpredictability and comprehension

- How can we implement dialogue systems that take into consideration
their environment? What is the role of the environment in addressing
comprehension difficulties?

- What are the most appropriate ways to evaluate dialogue systems for
different applications and situations? In particular, how does one
evaluate robustness when faced with comprehension difficulties?

This is the eighth IJCAI workshop on ``Knowledge and Reasoning in Practical
Dialogue Systems''. The first workshop was held at IJCAI in Stockholm
in 1999. The second workshop was held at IJCAI 2001 in Seattle, with a
focus on multimodal interfaces. The Third workshop was held in Acapulco,
in 2003, and focused on the role and use of ontologies in multi-modal
dialogue systems. The fourth workshop was held in Edinburgh in 2005,
and focused on adaptivity in dialogue systems. The fifth workshop, which
focused on dialogue systems for robots and virtual humans, was
held in Hyderabad, India, in 2007. The focus of the sixth workshop, held
in Pasadena, CA in 2009, was on challenges of novel applications of
practical dialogue systems, and the seventh workshop, held in Barcelona,
Spain, in 2011, considered dialogue systems for different types of users,
such as elderly people and people with special needs.


Who should attend

This workshop aims to bring together researchers and practitioners who
work on the development of communication models that support robust and
efficient interaction in natural language, both in basic research and in
commercial dialogue systems. The topic is timely, as dialogue systems,
in particular spoken ones, are ready to progress from toy or restricted
domains to more open-ended applications. As the applications become
more complex, so does the potential for comprehension difficulties,
which must be robustly handled.

The workshop should also be of interest to anyone studying dialogue
and multimodal interfaces. The proposed workshop emphasizes practical
research, e.g., empirical evaluations, formalization of dialogue
phenomena, and development of intelligent interfaces for various

As with the previous workshops in the series, we expect to benefit from
informal, high quality interactions between those interested and involved
in developing practical dialogue systems, including sharing of techniques
and experiences. Additionally, the theme of comprehension difficulties
is expected to attract participation from industry, as this is a common
problem in dialogue systems ranging from triage and slot-filling systems
to virtual reality systems. It is worth noting that while there has been
a fair amount of recent work in (spoken) dialogue systems, to the best
of our knowledge, there has not been a recent workshop that focuses on
comprehension difficulties.


Workshop format

The workshop will be kept small, as a one day workshop with a maximum
of 40 participants. Preference will be given to active participants
selected on the basis of their submitted papers.

Each paper will be given ample time for discussion, more than what is
customary at a conference. We will also encourage contributions of a critical
or comparative nature that provide fuel for discussion, and will invite people
to share their experiences of implementing and coordinating knowledge
modules in their dialogue systems, and integrating dialogue components
with other applications. Further, we hope to have contributions which
focus on the challenges of Chinese dialogue systems.


Important Dates
