摘要
针对综合集成研讨环境中的专家权威度评价问题,提出了一种基于SemRank的专家权威度计算方法。该方法既考虑专家之间的交互结构,又考虑专家发言内容之间的语义关联。由于专家之间的交互具有动态复杂性,在计算语义关联时,引入了时间衰减函数,反映时间这一要素的影响。实验结果表明,提出的专家权威度计算方法合理、有效;在综合集成研讨环境中,对促进专家良性互动和激发专家思维有一定的作用。
To solve the problem of measuring experts＇ authority in CWME,this paper proposed a method for estimating expert authority based on SemRank.This method not only considered the interactive structure between experts,but also took into account semantic relation between the experts＇ speeches.As the interaction between experts possessed dynamic complexity,introduced the time decay function to estimating semantic relation.Experimental result shows that the proposed method is feasible and effective.It lays a good foundation for experts to interact and inspire in CWME.
