基于设计人员需求的知识推送技术研究

摘要

In order to improve the design efficiency of the flight control system ,this paper proposes a knowledge push method based on flight control system designpersonnel requirement.It establishs the function modelof the design task and researchers interest model contained attributes and operations log. It also designsthe scoring method of interest in an item of interest model and extraction algorithm for information.On the basis of interest model ,it offers updating mechanism researchers interest model.It design knowledge matching algorithmbased on ontology semantic similarityand develops prototype system of knowledge pushfor flight control system design.The effectiveness of the proposed method is verified by examples.%为了提高飞行控制系统(简称飞控系统)的设计效率,提出了一种基于飞控系统设计人员需求的知识推送方法.建立了设计任务的功能模型和包含领域属性及操作日志的设计人员兴趣模型,并设计了兴趣模型中个兴趣项的计分方法和设计人员隐性信息提取算法.依据设计人员兴趣模型给出了设计人员兴趣模型的更新原理,设计了基于本体的语义相似度知识匹配求解算法.开发了面向飞控系统设计的知识推送原型系统.通过一个实例验证了本文提出方法的有效性.
