The problem of planning dialog moves can be viewed as an instance of the more general AI problem of planning with incomplete information and sensing. Sensing actions complicate the planning process since such actions engender potentially infinite state spaces. We adapt the Linear Dynamic Event Calculus (LDEC) to the representation of dialog acts using insights from the PKS planner, and show how...

In this paper we apply ideas from collaborative filtering to the problem of building dynamic Bayesian network (DBN) models for planning. We demonstrate that item-based collaborative filtering can be used to construct dynamic Bayesian networks for use in large, factored domains with sparse data. Such Bayesian networks can model the transition function for decision-theoretic planning. We demonstr...

The planning of publicly funded research and development programs can benefit from participatory foresight processes where research issues are evaluated with regard to multiple criteria. However, few approaches have been developed for the shaping of collaborative research networks through which the resulting priorities are implemented. We therefore develop a methodology for the joint shaping of...

To achieve efficient search performance for the multi-robot system which carries out the goal search task with consideration of timeliness, a multi-robot collaborative path planning system is designed to guide the robots during the search process. In the system, a planning method based on an Improved Ant Colony Optimization (IACO) algorithm is proposed. In the solution procedure, the path cost ...

One difficulty with existing theoretical work on HTN planning is that it does not address some of the planning constructs that are commonly used in HTN planners for practical applications. Although such constructs can make it difficult to ensure the soundness and completeness of HTN planning, they are important because they can greatly improve the efficiency of planning in practice. In this pap...

the present study aims to investigate the relative effectiveness of different types of pragmatic instruction including two collaborative translation tasks and two structured input tasks with and without explicit pragmatic instruction on the production of apologetic utterances by low-intermediate efl learners. one hundred and fifty university students in four experimental groups and one control ...

BACKGROUND Optimal applicator insertion is a precondition for the success of cervix cancer brachytherapy (BT). We aimed to assess feasibility and efficacy of MRI-assisted pre-planning, based on applicator insertion in para-cervical anaesthesia (PCA). PATIENTS AND METHODS Five days prior to BT, the pre-planning procedure was performed in 18 cervix cancer patients: tandem-ring applicator was in...

Abstract Helping pre-service teachers (PSTs) develop competencies in collaborative inquiry and knowledge building is crucial, but this subject remains largely unexplored CSCL. This study examines the design process of analytics-supported reflective assessment its effects on promoting PSTs to their building. We used a quasi-experimental that lasted 18 weeks. The experimental group was class 40 w...

the favorable gains gleaned from the provision of pre-task planning time (ptp) have struck a chord with sla researchers as they try to manipulate task features to promote language production and development. in a similar vein, the present study is a two-fold attempt to first compare the effect of the length of pre-task planning time on discourse-analytic measures in narrative written production...
