Ontology为需要共享某一领域信息的研究人员提供了通用的词表，而这正是传统的叙词表在信息检索中所起的作用。本文对叙词表向OntologY转换进行了综合性介绍，分别介绍了Ontology定义及作用、叙词表和Ontology的联系、Ontology所包含的内容和建立步骤以及叙词表转换为Ontology的研究和进展，最后结合一个具体实例加以阐述。  相似文献   

On the intrinsic value of information objects and the infosphere   总被引：4，自引：3，他引：4  

Luciano Floridi 《Ethics and Information Technology》2002,4(4):287-304

What is the most general common set ofattributes that characterises something asintrinsically valuableand hence as subject to some moral respect, andwithout which something would rightly beconsidered intrinsically worthless or even positivelyunworthy and therefore rightly to bedisrespected in itself? Thispaper develops and supports the thesis that theminimal condition of possibility of an entity'sleast intrinsic value is to be identified with itsontological status as an information object.All entities, even when interpreted as only clusters ofinformation, still have a minimal moral worthqua information objects and so may deserve to be respected. Thepaper is organised into four main sections.Section 1 models moral action as an information systemusing the object-oriented programmingmethodology (OOP). Section 2 addresses the question of whatrole the several components constituting themoral system can have in an ethical analysis. If theycan play only an instrumental role, thenComputer Ethics (CE) is probably bound to remain at most apractical, field-dependent, applied orprofessional ethics. However, Computer Ethics can give rise to amacroethical approach, namely InformationEthics (IE), if one can show that ethical concern should beextended to include not only human, animal orbiological entities, but also information objects. Thefollowing two sections show how this minimalistlevel of analysis can be achieved. Section 3 provides anaxiological analysis of information objects. Itcriticises the Kantian approach to the concept ofintrinsic value and shows that it can beimproved by using the methodology introduced in the first section.The solution of the Kantian problem prompts thereformulation of the key question concerningthe moral worth of an entity: what is theintrinsic value of x qua an object constituted by itsinherited attributes? In answering thisquestion, it is argued that entitiescan share different observable propertiesdepending on the level of abstraction adopted,and that it is still possible to speak of moral value even at thehighest level of ontological abstractionrepresented by the informational analysis. Section 4 develops aminimalist axiology based on the concept ofinformation object. It further supports IE's position byaddressing five objections that may undermineits acceptability.  相似文献   

基于本体论的数字图书馆搜索引擎的研究     

赵亚莉  魏淑琴 《现代情报》2007,27(8):104-106

基于本体（ontology）理论,利用本体对概念、术语及其相互关系的规范化描述,勾画出数字图书馆领域的基本知识体系,构建了数字图书馆领域本体库;然后,对现有的图书馆搜索引擎系统进行了改进,将构建的本体库引入到系统中,实现了基于本体的信息检索,方便用户对资源的查询,为用户提供高质量的个性化服务。  相似文献

杨建林 《情报理论与实践》2006,29(5):598-601

本文对如何构建基于本体的文本信息检索系统进行了探讨．并认为，利用反映概念之间关系的领域本体指导主题标引，利用反映实体之间关系的领域本体指导实体关系标引，并以本体的形式表示文档替代物和查询表达式，可以进一步提高文本信息检索系统的性能。  相似文献   

Digital Nominalism. Notes on the Ethics of Information Society in View of the Ontology of the Digital     

Tere?VadénEmail author 《Ethics and Information Technology》2004,6(4):223-231

The commodification of code demands two preconditions: a belief if the existence of code and a system of ownership for the code. An examination of these preconditions is helpful for resisting the further widening of digital divides. The ontological belief in the relatively independent existence of code is dependent on our understanding of what the “digital” is. Here it is claimed that the digital is not a natural kind, but a concept that is relative to our practices of interpretation. An interpretative system that sees code as something that can or should always be owned implies an increase of social control and threatens vital processes of knowledge creation that are necessary for an open and egalitarian information society. The ontological belief in “digital code” thus provides the backdrop for an ethical view of the information society. Consequently, if we see digital code as an interpretative notion (in the nominalist way), the ethical questions appear in a different light.  相似文献

数字环境下通用概念获取方法     

常春  赖院根 《图书情报工作》2011,55(22):22-25

在叙词表、本体等知识组织体系构建过程中,需要获取通用概念。笔者试验了三种获取通用概念的方法,一是继承传统知识组织体系通用概念,二是通过关键词在文献中词频分布情况确定通用概念,三是基于关键词总词频与标准差二维信息获得通用概念。研究结果表明：以上三种方法各有特点及使用范围,在概念获取时可以根据课题具备条件单独使用或组合使用。   相似文献
