The creation of an instance of a knowledge structure, and optionally assigning a value to all or portions of that structure. In most rule□based 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). 建立知識結构的一个实例,并可選擇性地給該結构的全部或一部分賦值。在大部分基于 知識規則的專家系统中,它在功能上等价于普通數据处理中“賦值”語句,但在支持 對象/属性/值三元組的系统(M.1, KES及Personal Consultant Plus)中,該朮語還指軟件 不需要開发者特別控制,即可动態地建立數量不确定的對象实例的能力(稱為多例化)。
