尽管基于概率模型的检索系统将根据某个匹配标准(例如,相关性)的概率来对正被检索的对象(例如,文档)进行排名,但它们很少产生实际概率,并且评分函数被解释为在给定检索任务内是纯粹有序的。在这个简短的交流中,一些评分函数具有似然性质,这意味着评分函数指示了与其他检索任务相比的匹配可能性,这可能比纯粹的排序更有用,尽管它不能解释为实际的概率。这一属性可以通过使用两个修改后的有效性度量来检测:整体查准率和整体召回率。
Although retrieval systems based on probabilistic models will rank the objects (e.g., documents) being retrieved according to the probability of some matching criterion (e.g., relevance), they rarely yield an actual probability, and the scoring function is interpreted to be purely ordinal within a given retrieval task. In this brief communication, it is shown that some scoring functions possess the likelihood property, which means that the scoring function indicates the likelihood of matching when compared to other retrieval tasks, which is potentially more useful than pure ranking although it cannot be interpreted as an actual probability. This property can be detected by using two modified effectiveness measures: entire precision and entire recall.
