The notion of relevance is central to many theoretical and practical
information retrieval models. Traditional retrieval models assume
that the relevance of a document is independent of the relevance
of other documents. This makes it possible to formulate
the retrieval problem as computing a relevance value for each document separately, and then ranking documents by relevance [6].
In reality, however, this independent relevance assumption rarely
holds; the utility of retrieving one document, in general, may depend on which documents the user has already seen. As an extreme
example, a relevant document may be useless to a user if the user
has already seen another document with the same content.

相关性的概念是许多理论和实际信息检索模型的核心。传统检索模型假设一个文件的相关性独立于其他文件。使得我们能够对每个文件的相关值独立运算以规范化检索问题，然后按文件相关程度排序[6]。然而事实上，“相关性是相互独立的”这种假设很少站得住脚；一般来讲，用户是否使用检索到的文件可能取决于用户已看到的文件。一个极端的例子，如果用户已看到有相同内容的其他文件，一个尽管具有相关性的文件对用户就可能是无用的。
