属性约简在教学质量评估系统中的应用

粗集是一种处理不精确的、不一致的、不完整的各种不完备信息,并从中发现隐含的知识,揭示潜在规律的方法,可以应用于数据挖掘,其中属性约简和核是粗集的核心内容。在教学质量评估系统中,为了得出评价的规律,必须对收集的众多信息指标进行处理,其中有些指标是关键的,获取这些指标有助于提高管理的成效。文中应用粗集理论对教学质量评估指标进行约简,获取最优的指标,在教学管理中有很大的价值。

Application of Property Reduction to Teaching Quality Evaluation System

Rough set is a tool in analyzing and processing the imprecise, inconsistent and incomplete information, and finding the connota-tive knowledge, potential regulations and methods. It can be applied in data mining. Property reduction and core are the kernel contents of rough set . The Teaching Quality Evaluation System can process many gathered information indexes, in which some are key. Getting those indexes help improving the effectiveness of management. The paper applies the theory of rough set in reduction of teaching quality e-valuation indexes and getting the optimal indexes. It is very valuable in factual teaching management.
