Abide by the principles of " to first realize that different ones have the same cognizance about the same terms and then to realize information sharing " , we use ontology to describe the critical terms in distance learning and to structuralize and to provide equivalence criteria , and at the same time it can effectively reduce the semantic conflicts and facilitate the interoperability among different data sources 由于教育系統(tǒng)的多元化,使得不同的系統(tǒng)對(duì)教育詞匯的定義往往產(chǎn)生分歧,針對(duì)這種現(xiàn)狀,我們本著先實(shí)現(xiàn)共知,后實(shí)現(xiàn)共享的原則,運(yùn)用本體描述領(lǐng)域中的關(guān)鍵術(shù)語(yǔ),建立領(lǐng)域詞匯表,為信息共享創(chuàng)造條件。
