The basic assumption is that the terms that have almost the same probability of being observed within the results of a query and also in the entire PubMed database (excluding the results of the query) do not contain important information specific to the documents related to the query

基本假设是:一个词在检索结果文献集中被观察到的概率,如果与其在整个数据库(排除掉检索到文献集)中出现的概率无异的话,那么这词就不会包含重要的信息,这个信息的重要性是相对于与检索策略相关文献来说的。


用“jamia[jour]”检索所有发表在美国医学信息学会杂志的文章,结果是这样的:


'jamia[jour]< 3328 PubMed documents | MeSHy | cite us | code | contact us | BAT cave

会不会太重视罕见词了呢?
