Through examples, it shows that attribute reduction of an inconsistent decision table cannot entirely be represented by conditional information quantity.

并举例说明，对于不一致决策表，其属性约简的代数表示不能用条件信息量来等价表示。

It's really a technology initiative that's aimed to index the "dark" web or the hidden web, because according to computer scientists, right now the conditional search engines only index about 1% of the information on the Internet.

这是一项,致力于将暗网,或隐藏网页纳入索引的技术创新，根据计算机科学家的统计，条件式的搜索引擎只将,互联网上1%的信息纳入了索引。
