AbstrAct: This paper focuses our agent-based approach to dialogue management equipped with a deliberation mechanism further extensible with additional features. The aim of this study has been to create a manager which can exhibit complex behaviour from two points of view – the development and runtime ones. To support the first case, the domain developer needs to provide a set of plans which tel...

In this work, an explicitly task-oriented approach to the active vision problem is presented. The system tries to reduce the most relevant components of the uncertainty in the world model, for the task the robot is currently performing. It is task oriented in the sense that it explicitly considers a task-specific value function. As test-bed for the presented active vision approach, we selected ...

This paper addresses the problem of optimal grasping of an object with a multi-fingered robotic hand for accomplishing a given task. The task is first demonstrated by a human operator and its force/torque requirements are captured through the usage of a sensorized tool. The grasp quality is computed through a task compatibility criterion. Grasp synthesis is then formulated as a single constrain...

Many clinical tasks depend upon the proper interpretation of medical images and will benefit from access and reference to similar, relevant images. In this paper, we present CBIR approaches to two clinical tasks and discuss their specific challenges. The first CBIR system retrieves anatomical regions in Computed Tomography (CT) studies of the chest and abdomen. The system can be used to provide...

We introduce the notion of a task-oriented maximally entangled state (TMES). This notion depends on the tasks for which a quantum state is used as the resource. This concept may be more fruitful than that of a general maximally entangled state in the case of a multipartite system. We illustrate this idea by giving an operational definition of maximally entangled states on the basis of communica...

In this paper, we explore the mechanisms by which conversants control the direction of a dialogue. We find further evidence that control in task-oriented dialogues is subordinate to discourse structure. The initiator of a discourse segment has control; the non-initiator can contribute to the purpose of the segment, but this does not result in that person taking over control. The proposal has im...

Abstract The associations among readers’ cognitive skills (general ability, reading skills, and attentional functioning), task demands (easy versus difficult questions), process measures (total fixation time on relevant irrelevant paragraphs) was investigated to explain task-oriented accuracy efficiency (number of scores in a given unit). Structural equation modeling applied large dataset colle...
