摘要
预警有助于及时预防和解决隐患,具有重要的应用价值,受到了广泛的关注。提出了一种新的预警机制,以领域相关的预警知识为基础构建预警系统,重点研究了以实际数据为资源,基于背景领域知识挖掘出预警规则,使得预警系统中的预警知识更丰富、更完备、更具有实际应用价值。将上述研究应用于高校教学教务系统的学生成绩预警,实验结果表明所提出的预警机制和方法是有效的。
The early warning is beneficial to prevent and solve hidden trouble in good time, accordingly warning study has important value. The mechanism and method of the early warning are concerned widely. A new warning mechanism was proposecl to construct early warning system based on domain early warning knowledge in the paper. Concentrated mainly in mining early warning rules based on background domain knowledge from the real data, to make early warning knowledge richer, more complete and with more practical value. Applying the mechanism and method to resolve early warning problems of student achievement data in a university educational administration management information system. Experimental results suggest that they can work reasonably well.
