1、摘要本體傲為語(yǔ)義鼴絡(luò)中表示W(wǎng)eb信息語(yǔ)義的一層,用于描述某個(gè)領(lǐng)域內(nèi)的概念以及它們之間的聯(lián)系,是解決語(yǔ)義層次Web信息共享和交換的基礎(chǔ)。這些不盡相網(wǎng)的本體盡管是對(duì)同一領(lǐng)域進(jìn)行描述,但是由于它們是對(duì)該領(lǐng)域不同劃分層面的描述和不可避免包含著重復(fù)的信息,這就給不同本體之間的交互和重用帶來(lái)了很大的困難,本體整合就成了解決這個(gè)問(wèn)題的必然途徑。本文中將本體工程中的相關(guān)理念及其相關(guān)技術(shù)引入到本體整合的應(yīng)用系統(tǒng)當(dāng)中,針對(duì)本體整合的具體領(lǐng)域進(jìn)行本體的構(gòu)建工作,采用本體理念對(duì)其對(duì)象及相關(guān)屬性進(jìn)行描述。在文中對(duì)整合工作
2、中涉及到的語(yǔ)義網(wǎng)與本體的研究問(wèn)題,映射問(wèn)題及相似度計(jì)算模型進(jìn)行了深入的討論,在此基礎(chǔ)上詳細(xì)闡述了針對(duì)兩個(gè)電子本體的本體整合實(shí)驗(yàn)的具體實(shí)現(xiàn)過(guò)程及其中所涉及到的關(guān)鍵技術(shù)及及箕技術(shù)的實(shí)現(xiàn)。在本文的實(shí)驗(yàn)中實(shí)現(xiàn)了基于OWL格式的本體整合,首先通過(guò)對(duì)OWL結(jié)構(gòu)特征的分析抽取出主要信息并以樹(shù)型結(jié)構(gòu)進(jìn)行顯示,然后通過(guò)元素層次和結(jié)構(gòu)層次相結(jié)合的映射方法,對(duì)領(lǐng)域本體進(jìn)行整合操作。引入本體Wordnet做為詞典輔助,用以解決語(yǔ)義層次方面的問(wèn)題,并利用基于統(tǒng)計(jì)的方法消除歧義。根據(jù)這些原理,開(kāi)發(fā)出面向同一領(lǐng)域的本體整合工
