| 术语 | instantiation |
| 释义 | instantiation 例化 The creation of an instance of a knowledge structure, and optionally assigning a value to all or portions of that structure. In most rulebased products, it is functionally equivalent to a conventional data processing “assignment” statement. However, in systems supporting o/a/v triplets (M.1, KES, and Personal Consultant Plus), the term additionally refers to the software's ability to dynamically create indefinite numbers of object instances without specific developer control (referred to as multiple instantiation). 建立知识结构的一个实例,并可选择性地给该结构的全部或一部分赋值。在大部分基于 知识规则的专家系统中,它在功能上等价于普通数据处理中“赋值”语句,但在支持 对象/属性/值三元组的系统(M.1, KES及Personal Consultant Plus)中,该术语还指软件 不需要开发者特别控制,即可动态地建立数量不确定的对象实例的能力(称为多例化)。 |
