作者以广义检索效用评价理论为支持,提出了适用于多值相关性判定的最佳输出排序原则,并以此为基础,建立了概率检索模型。
By making use of the general retrieval effectiveness evaluation theory as his support, the author brings forth the optimum output ranking principle adapted to the multi-value relevance judgment, and with that as the basis, establishes the probabilistic retrieval models.
