摘要
为实现工艺知识挖掘的自动化及工艺知识的及时更新,提出了基于语义结构的产生式规则工艺知识表示法,通过词汇链及特征表达式析取出关键词并形成工艺知识词汇链;为提高知识挖掘效率,提出了工艺知识挖掘机模型并给出了该模型的工作原理及知识挖掘策略。
For the automation of process rules mining and updating process rules in time, an expression of production rule based on semantic structure is prompt. To improve the efficiency of process rules mining, a model of process rules mining machine is given. The operation principle and mining strategy of the process rules mining machine are discussed. Considering the difficulty of system integration, a partitioning algorithm is adopt to abbreviate the precondition factors of process rules and make the process rules more accessible.
