| 摘 要： | 研究了如何在知识发现中处理属性值缺损的问题，通过发现值缺损属性的取值集合，值缺损属性是否为强作用属性以及与其他属性是否相关。不仅解决了对含有缺损数据信息源进行知识发现的问题，同时也说明了对缺损数据处理的意义。

| Abstract: | The problem of dealing with imperfect information in knowledge discovery is studied in this paper. Efforts have been made to find the set of values which the attributes with incomplete values may take and to determine whether the attributes are of strong effect or correlated with others, resulting in a satisfactory solution to such a problem. |

| Keywords: | knowledge discovery correlated attribute strong effect attribute imperfect information |
