场景构造是机会发现过程中的关键活动之一。对机会发现场景的结构进行形式化描述,提出基于布尔相关矩阵并利用聚类分析的方法构造事件簇,进而实现机会发现简单场景构造的思想并给出实现方法。对机会发现场景构造方法性能的评估进行探讨,明确以效率系数作为机会发现场景构造方法的评估标准。实验表明,该方法的效率系数较高。

The construction of scenario map is one of key activities in the process of chance discovery.The formalization description of the structure of scenario map in chance discovery is presented.With this formalization description,the principle for the construction of event clusters in scenario map via clustering analysis based on Boolean correlation matrix and the construction of simple scenario map based on event clusters are given and the algorithm for the implementation of the principle is given.The evaluation criterion for the performance of methods for the construction of scenario map in chance discovery is discussed and efficiency coefficient is used as the criterion definitely.Experimental results show that the performance of the algorithm on the construction of simple scenario map is good with greater efficiency coefficient.
