基于多级框架的不确定知识推理方法研究
Research on Method of Uncertain Knowledge Reasoning Based on Multilevel Framework
摘要
Abstract
In the process of knowledge reasoning applied to the intelligent method,in order to solve the problem of concurrency matching of knowledge and usability,a method of uncertainty reasoning under multi-level framework is designed. With introduction of rule-knowl-edge derivation,establishment of the production model and design of multi-level frame structure,its precision and accuracy of reasoning is improved effectively;introducing slot value coincidence rate and membership degree as confirmation factor as well as knowledge con-currency matching,the forward-based reasoning is adopted as knowledge reasoning and the Bayes method applied to eliminate conflict in knowledge matching. Experiments on its accuracy and concurrent reasoning have been conducted with some concurrent abnormal sam-ples,which show that its accuracy and concurrent reasoning is promoted greatly,achieving the purpose for reasonable design of knowledge structure and significant improvement in knowledge abstraction,meeting the refinement requirements of complex industrial production in the field of multi concurrent reasoning. The analysis on results of practical testing early dynamic warning for oil well production show that the proposed UnMF method has improved accuracy of early warning,which can reduce the occurrence of abnormal production and there-fore is of great significance for stable and efficient industrial production.关键词
