简介：在利用RDF和OWL获取本体元信息的基础上,结合Ontology的分析,探讨了构建概念、语义检索系统的方法,从而实现电子文本知识的挖掘.

简介：＂不可译性＂在概念词的翻译中尤为突出,其原因在于概念总是与其他概念相连,概念与整个概念体系、甚或整个思想体系相连。＂Ontology＂是西方哲学中一个关键的概念词,其实质是研究being的一门学问,其产生是缘于being在西方语言使用中所独具的＂普遍性＂。本文在对＂Ontology＂进行词典学考察基础上,从决定其意义的关键词＂being＂在西方哲学中和在日常语言中的使用入手,并结合＂Ontology＂产生的理论背景以及中西方语言和思想的巨大差异,对其＂不可译性＂进行了全面辨析。有鉴于此,对于类似的概念词,要消解其＂不可译性＂,从本质上看,只能在目的语语境中思考如何对其进行＂再命名＂。

简介：这份报纸建议一个本体论驱动的发现模型让地理信息服务改进他们的召回比率和精确比率。这个模型使用地理信息服务本体论。在这份报纸，首先，我们学习匹配地理信息服务的算术的multilevel。这算术被用于根据选择的服务和从功能类似的定义请求的服务的类似和信用站类似在服务收款机中心过滤并且匹配服务。匹配的算术，地理信息服务本体论和语义描述组成发现模型。最后，我们从召回比率，精确比率，responsivity和负担平衡测试并且分析模型。结果显示本体论驱动的发现模型在召回比率和精确比率是优秀的，并且能维持服务拷贝的动态负担平衡。

简介：传统信息检索模型不能很好满足用户的需求,本文在分析现有相关研究的基础上,提出了基于领域Ontology的知识检索模型。通过构建领域Ontology,对文档进行语义标注,对查询请求进行概念提取和语义扩展,从而得到了语义索引项作为文档和用户请求的知识表达,进一步研究领域Ontology中词语间语义关系的计算模型。考虑到语义相似度与语义相关的内在关系,给出相关系数来衡量检索目标与候选者间符合程度。最后对本文提出的模型进行了验证,表明检索性能有了显著提高。
