On Mixed-Initative Planning and Control for Autonomous Underwater Vehicles
Supervision and control of Autonomous underwater vehicles (AUVs) has traditionally been focused on an operator determining a priori the sequence of waypoints of a single vehicle for a mission. As AUVs become more ubiquitous as a scientific tool, we envision the need for controlling multiple vehicles which would impose less cognitive burden on the operator with a more abstract form of human-in-the-loop control. Such mixed-initiative methods in goal-oriented commanding are new for the oceanographic domain and we describe the motivations and preliminary experiments with multiple vehicles operating simultaneously in the water, using a shore-based automated planner
Incorporating social practices in BDI agent systems
When agents interact with humans, either through embodied agents or because
they are embedded in a robot, it would be easy if they could use fixed
interaction protocols as they do with other agents. However, people do not keep
fixed protocols in their day-to-day interactions and the environments are often
dynamic, making it impossible to use fixed protocols. Deliberating about
interactions from fundamentals is not very scalable either, because in that
case all possible reactions of a user have to be considered in the plans. In
this paper we argue that social practices can be used as an inspiration for
designing flexible and scalable interaction mechanisms that are also robust.
However, using social practices requires extending the traditional BDI
deliberation cycle to monitor landmark states and perform expected actions by
leveraging existing plans. We define and implement this mechanism in Jason
using a periodically run meta-deliberation plan, supported by a
metainterpreter, and illustrate its use in a realistic scenario.Comment: An extended abstract of this paper has been accepted for the

A discourse-based approach to verb placement in early West-Germanic
The paper presents a novel approach to explaining word order variation in the early Germanic languages. Initial observations about verb placement as a device marking types of rhetorical relations made on data from Old High German (cf. Hinterhölzl & Petrova 2005) are now reconsidered on a larger scale and compared with evidence from other early Germanic languages. The paper claims that the identification of information-structural domains in a sentence is best achieved by taking into account the interaction between the pragmatic features of discourse referents and properties of discourse organization

The Power of Modeling - a Response to PDDL2.1
In this commentary I argue that although PDDL is a very useful standard for
the planning competition, its design does not properly consider the issue of
domain modeling. Hence, I would not advocate its use in specifying planning
domains outside of the context of the planning competition. Rather, the field
needs to explore different approaches and grapple more directly with the
problem of effectively modeling and utilizing all of the diverse pieces of
knowledge we typically have about planning domains
