铜矿床领域本体的构建方法研究

摘要

China has favorable metallogenic geological conditions of copper deposits,while the proven copper resources cannot fully meet the need of national construction.Geological data and literature related to copper deposits can be effectively managed and retrieved according to knowledge structure,but the method of constructing mineral resources domain ontology is still under exploration.This paper puts forward a semi-automatic method of constructing copper deposits domain ontology,which can organize the knowledge of copper deposits in the form of ontology,so as to further support the prospecting work in China.First of all,copper deposits are classified refer to relevant literature and monograph,which are described for various types in accordance with industry general principles and regulations,establish conceptual model for copper deposits domain ontology.Secondly,in order to perfect the copper deposits domain ontology,examples and expert opinion are added into all types of copper deposits.Finally,the construction of copper deposits domain ontology is realized by visualization in the Protégé environment.The domain ontology of copper deposits constructed by this method has the characteristics of clear knowledge level,clear definition of relation and rich examples.It can be applied to the accurate recommendation of geological information retrieval,and lay a foundation for the integration and sharing of copper deposits resources information.%我国铜矿成矿地质条件较好,但已探明的铜矿资源还不能完全满足国家建设的需要.按知识结构组织地质勘查资料可以有效管理和检索铜矿相关的地质资料和文献,但构建矿产资源领域本体的方法尚在探索中.本文提出了铜矿床领域本体的半自动化构建方法,能够将铜矿床的知识以本体的形式组织起来,从而进一步支撑我国的找矿工作.首先,通过参考相关专著和文献对我国铜矿床进行成因分类,按照行业相关总则和规范对各类型铜矿床进行相关描述,建立起铜矿床领域本体的概念模型.其次,添加各类铜矿床实例,并参考领域专家建议,完善铜矿床领域本体.最后,通过可视化的方式,在Protégé环境中实现了铜矿床领域本体的构建.通过该方法构建的铜矿床领域本体具有知识层次清晰、关系定义明确、实例丰富的特点,应用于地质资料检索中的精准推荐,为铜矿床资源信息的集成和共享打下基础.
