摘要:
分析了群体感知模型的研究现状, 发现现有的群体感知模型对任务关系的考虑不够全面, 大多数模型仅利用任务间的层次关系进行感知计算, 而对任务间的其他依赖关系缺乏考虑. 本文首先讨论了任务在群体感知中的重要性, 对任务依赖关系进行了深入研究, 进而提出一种新的基于任务依赖关系的群体感知模型TBGAM, 并重点阐述了TBGAM模型的形式化定义及主要感知机制. TBGAM模型利用任务的资源依赖图和时态依赖矩阵分别表示任务间基于资源和基于时间的依赖关系, 在此基础上重新考虑群体感知强度的计算方法, 把任务的依赖关系应用于感知强度的计算中, 帮助用户确定感知空间, 获得了更加合理的感知效果.
Abstract:
The stale-of-art of the group awareness models is analyzed and it is found that they lack comprehensive consideration of relations among tasks. Most of the models only use hierarchy relations of tasks in awareness calculations, ignoring task dependencies. In this paper, the importance of task in group awareness is discussed first, then the dependency relations among tasks are deeply investigated and finally a new task dependency-based group awareness model (TBGAM) is proposed. The formal definition and main awareness mechanisms of TBGAM are expounded. TBGAM uses a resource dependency graph of task to represent task relations based on resource and uses temporal dependency matrix of task to represent task relations based on time. Based on this, the calculating methods of group awareness intensities are reconsidered and task dependencies are applied to calculate awareness intensities. The model helps users to identify awareness spaces and to acquire sound effects of awareness.
