摘 要:[目的/意义]遵循领域知识功能结构的组织规律,基于多维特征属性挖掘领域知识研究前沿,提高领域知识发现的可利用率.[方法/过程]以民机适航“WoS核心合集数据库提取的523条中被引频次超过5的前100篇文献”为研究对象,概括归纳该研究领域的功能性结构特征,基于民机适航领域知识功能结构层次,构建渗透贯穿专业领域知识功能结构多维特征属性分类,实施三维图示和粗糙集数据挖掘,多维度交叉关联获得研究热点.[结果/结论]基于功能结构多维特征属性,深入细化领域知识结构化组织架构内容,挖掘领域知识研究前沿信息端倪,能够促进知识发现从传统型的数据驱动向新型的符合领域知识结构规律的挖掘转型.[局限]基于功能结构多维特征属性,挖掘领域知识研究前沿的实现技术方法和手段尚需完善.[Purpose/significance]This paper aims to follow the organizational rule of domain knowledge function structure,mining domain knowledge based on multi-dimensional feature attributes can improve the availability of domain knowledge discovery.[Method/process]Taking the first 100 references cited more than 5 times in 523 extracted from WoS core collection database on airworthiness of civil aircraft as the research object,the functional structure characteristics of this research field are summarized,the multi-di mensional feature attribute classification of knowledge functional structure penetrating the professional field is constructed by being based on knowledge function structure level of civil aircraft airworthiness domain,the three-dimensional graphics and rough set data mining are implemented,and the multi-dimensional cross-correlation is the research hotspot.[Result/conclusion]Based on the multi-dimensional feature attributes of functional structure,further refinement of the content of domain knowledge structured organizational structure and mining the frontier information of domain knowledge research can promote the transformation of knowledge discovery from traditional data-driven to new mining conforming to the rules of domain knowledge structure.[Limitations]Based on multi-dimensional feature attributes of functional structure,there is no mature platform to fully realize the realization technology and means of mining the frontier of domain knowledge research.
