CSCW系统中基于角色的感知模型

Implemention of Role-based Awareness Model in CSCW

感知是CSCW系统中需要解决的关键技术问题之一,因此,本文提出一种基于层次图的角色感知模型:模型通过角色与原子任务之间的归属关系和原子任务的交互关系建立层次图,同时对非原子任务进行分解;通过起始原子任务发起简化算法,并在算法中引入角色合并规则;以简化后的角色为基础在P2P网络下建立虚拟工作组,给出了虚拟工作组间的消息分发机制.实验表明,该方案在协作节点大量增加的情况下降低了数据反馈延时,更易于满足CSCW中感知的高实时性的要求.

Awareness is an important research field in CSCW community. This paper presents a role-based awareness model on the basis of hierarchical graph. It establishes hierarchical graph through the relegable relationships of the role and atomic tasks and interactive relationships of atomic tasks, meanwhile decompose non-atomic tasks. Then,it presents simplified algorithm through the original atomic task and introduces role merging rules into the algorithm. The model creates virtual working groups on the basis of the simplified roles and makes the messages delivery mechanism. Experiment results show that this method can effectively decrease delay time with the increasing of collaboration nodes and is easier to meet the CSCW awareness with higher real time demand.
