【摘要】:本文引入知識元對煤礦事故領(lǐng)域的信息、知識的描述、組織等有關(guān)問題進(jìn)行研究。首先,根據(jù)共性知識元模型的特點(diǎn)在傳統(tǒng)描述邏輯ALC(Attributive Concept Description Languagewith Complements)基礎(chǔ)上通過擴(kuò)展概念和關(guān)系、添加反關(guān)系構(gòu)造器提出了描述邏輯KEDL(知識元描述邏輯),建立了KEDL的語法、語義、公理體系,證明得出KEDL語法推論和語義推論等價(jià)等性質(zhì);其次,采用系統(tǒng)論把面向應(yīng)急管理的煤礦事故涉及的相關(guān)事物分為煤礦事故系統(tǒng)、煤礦客觀事物系統(tǒng)、應(yīng)急管理活動系統(tǒng),分別把其分到管理學(xué)范疇下不可再分,,提取其對應(yīng)的屬性要素及關(guān)系,基于共性知識元模型分別建立了表達(dá)煤礦事故領(lǐng)域所涉及的相關(guān)事物和信息的三種知識元及它們的模型;另外,基于本體論建立了煤礦事故領(lǐng)域知識元本體模型,該模型由煤礦客觀事物系統(tǒng)知識元本體、煤礦事故知識元本體、煤礦事故應(yīng)急活動知識元本體組成;最后,基于復(fù)雜網(wǎng)絡(luò)對煤礦事故領(lǐng)域知識元網(wǎng)絡(luò)進(jìn)行研究,建立其數(shù)學(xué)模型,從收集大量事故案例中提取知識元及關(guān)系,建立了煤礦事故領(lǐng)域知識元網(wǎng)絡(luò),分析得到該網(wǎng)絡(luò)具有小世界和無標(biāo)度等特性。通過實(shí)例驗(yàn)證,本文提出的邏輯系統(tǒng)和相關(guān)知識元模型是合理的。
[Abstract]:In this paper, knowledge element is introduced to study the information, knowledge description and organization in the field of coal mine accidents. First of all, according to the characteristics of the generic knowledge metamodel, based on the traditional description logic ALC (Attributive Concept Description Languagewith Complements), the description logic KEDL (knowledge meta-description logic) is put forward by extending the concept and relation, and the syntax and semantics of KEDL are established. The axiomatic system proves that the KEDL grammar inference and semantic inference are equivalent. Secondly, the system theory is used to divide the related things involved in coal mine accidents for emergency management into coal mine accident system, coal mine objective thing system, and so on. The system of emergency management activities, which is divided into two categories of management, can not be further divided, and extracts its corresponding attribute elements and relationships. Based on the common knowledge element model, three kinds of knowledge elements and their models are established to express the related things and information in the field of coal mine accident, in addition, the ontology model of knowledge element of coal mine accident field is established based on ontology. The model is composed of knowledge element ontology of coal mine objective object system and knowledge element ontology of coal mine accident emergency activities. Finally, based on complex network, the knowledge element network in coal mine accident field is studied. The mathematical model is established, the knowledge element and its relationship are extracted from a large number of accident cases, and the knowledge element network in the field of coal mine accident is established. It is found that the network has the characteristics of small world and no scale. The logical system and related knowledge metamodel presented in this paper are reasonable.
