In the present study, two different models of task complexity; namely, limited attentional capacity model and cognition hypothesis were examined. To this end, the manipulation of cognitive task complexity along +/- single task dimension on Iranian EFL learners’ production in terms of fluency was explored. Based on the results of the writing test of TOFEL (2004), 48 learners were selected as the...

The coordination language Opus is an object-based extension of High Performance Fortran (HPF) that supports the integration of coarse-grain task parallelism with HPF-style data parallelism. In this paper we discuss Opus in the context of multidisciplinary applications (MDAs) which execute in a heterogeneous environment. After outlining the major properties of such applications and a number of d...

This paper proposes a cognitive architecture of an intelligent agent that can have a dialogue with a human agent on health-related topics. This architecture consists of four main components, namely, the Belief Base, the Dialogue Manager, the Task Manager and the Plan Generator. Each component has sub-components that perform a set of tasks for the purpose to enable the agent to be enrolled in a ...

This paper proposes a deep convolutional neural model for character-based Chinese word segmentation. It first constructs position embeddings to encode unigram and bigram features that are directly related to single positions in input sentence, and then adaptively builds up hierarchical position representations with a deep convolutional net. In addition, a multi-task learning strategy is used to...

Wireless sensor network (WSN) applications sense events in-situ and compute results in-network. Their software components should run on platforms with stringent constraints on node resources. To meet these constraints, developers often design their programs by trial-and-error. Such manual process is time-consuming and error-prone. Based on an existing task view that treats a WSN application as ...

Workflow problems generally require the coordination of many workers; machines and computers. Agents provide a natural mechanism for modelling a system where multiple actors operate, but they do not explicitly support coordination schemes. Efficient task allocation to these actors is a fundamental coordination prerequisite. A competent allocation policy should address both system performance is...

Distributed troubleshooting often requires experts to support non-experts at a distance. The resulting separation between collaborators can impoverish their understanding of each other’s task contexts, impeding their collaboration. Consequently, this paper argues that developing effective troubleshooting support systems requires determining (1) what contextual information the participants requi...

Cultural diversity can have both positive and negative effects on the performance of multinational teams. Positive effects can stem from the wide variety of experiences and methods that a culturally diverse team can draw on to plan and to develop innovative or efficient solutions to a complex problem. However, cultural diversity can also lead to miscommunications and misunderstandings during ta...

The coordination between agent service and Web service is the key factor for intelligent Web service management in the multi-agent based Web service framework. In view of the drawbacks of existing coordination approaches for agent service and Web service, this paper proposed a multiagent and workflow-based Web service management model. Through analyzing the interaction relations between agent s...
