Abstract: In order to solve the problems of strong professionalism, high difficulty and low rate of knowledge reuse in the scheme and outline design for operational test and in?service assessment of engineering equipment (engineering equipment experiments design), a knowledge retrieval system is proposed. An ontology model for the field of engineering equipment experimental design is constructed for the first time, so as to realize the standardized representation of case knowledge, and lay the foundation for knowledge reuse. In order to improve the accuracy of case retrieval, the two?level retrieval method based on semantic similarity of engineering equipment is proposed, which can achieve precise one?time and secondary push of similar cases before and during the design process. Taking the design of in?service assessment outline for a certain type of self?propelled pontoon bridge equipment as an example for testing, the testing results show that the designed system can improve the efficiency and scientificity of experimental design in the field of engineering equipment.
Keywords: engineering equipment; experimental design; semantic similarity; knowledge retrieval; knowledge reuse; ontology model; synonymous extension
0" 引" 言
工程裝備試驗(yàn)主要是檢驗(yàn)裝備作戰(zhàn)效能和各類適用性指標(biāo)的系統(tǒng)性活動,為裝備的優(yōu)化設(shè)計、改進(jìn)改型提供意見建議[1]。其科學(xué)有效開展的前提是工程裝備作戰(zhàn)試驗(yàn)與在役考核方案和大綱的設(shè)計(以下簡稱工程裝備試驗(yàn)設(shè)計)。考核方案與大綱設(shè)計涉及多學(xué)科知識交叉、多專業(yè)、多層次,是知識高度密集的復(fù)雜過程,存在指標(biāo)體系構(gòu)建難、考核科目設(shè)計難等問題[2]。
目前,考核方案與大綱設(shè)計依賴于專業(yè)人員的經(jīng)驗(yàn)積累,輔以手冊、圖書等,缺乏對工程裝備試驗(yàn)設(shè)計領(lǐng)域顯性及隱形經(jīng)驗(yàn)知識的規(guī)范化表示和檢索重用,設(shè)計效率低、難度大。
本體[3]是對特定領(lǐng)域內(nèi)概念、術(shù)語及關(guān)系進(jìn)行抽象而建立的一種形式化知識描述,可實(shí)現(xiàn)領(lǐng)域內(nèi)知識的規(guī)范化表示,為知識檢索重用提供基礎(chǔ)。……
