    • For every item, plural kinds of attribute data are registered beforehand in a data base (21). Preset is a retrieval condition (23) comprising a plurality of premise conditions which are desired conditions on at least part of the plural kinds of attribute data, and coupling conditions for coupling these premise conditions with each other. The degrees of relevancy that the attribute data are relevant to the preset premise conditions are calculated by an operation control unit (24). According to the preset coupling conditions, executed are at least one of a MEAN operation (25) for calculating the average value of those degrees of relevancy, a MIN operation (26) for picking up the minimum value from among those degrees of relevancy, and a MAX operation (27) for picking up the maximum value from among those degrees of relevancy. Then, outputted is the signal for representing the degree of coincidence which is obtained by these operations.
    • 对于每个项目,预先将多种属性数据登记在数据库(21)中。 Preset是包括作为多种属性数据的至少一部分上的期望条件的多个前提条件以及用于将这些前提条件相互耦合的耦合条件的检索条件(23)。 通过操作控制单元(24)计算属性数据与预设前提条件相关的相关度。 根据预设的耦合条件,所执行的是用于计算那些相关度的平均值的MEAN操作(25),用于从那些相关度中拾取最小值的MIN操作(26)中的至少一个,以及 MAX操作(27),用于从这些相关度中选取最大值。 然后,输出用于表示通过这些操作获得的重合度的信号。
