Afterwards, modeling-based knowledge base, especially the hierarchical knowledge base, is discussed in the thesis . on the bases of deriving and improving the hierarchical knowledge modeling of commonkads, an ontology-based knowledge system modeling framing is advanced in the thesis . around ontology, the main components of the modeling framing are problem solving method, method ontology, psm description ontology, domain ontology and so on 然后,本文對基于模型的知識系統(tǒng)進(jìn)行了研究,并深入探討了層次化知識模型,在改進(jìn)和吸取commonkads層次化知識模型的基礎(chǔ)上,提出了一種基于本體的知識系統(tǒng)建模框架omkbs,該建模框架以本體為核心,主要包括問題求解方法(psm)、方法本體、psm描述本體、領(lǐng)域本體等相互獨立的組件,每個組件可以實現(xiàn)一定條件下的重用。
