一直很迷惑 Concepts Ontology Terminology

老包

最初由 linforest 发表
[B]一直很迷惑
Concepts Ontology Terminology
三者的差别

向您请教...
谢谢! [/B]

我的理解是:

Concepts概念是一个较宽泛的意识单元;

Ontology被称为"概念模型",实际上是一个严格结构化(主要以框架形式表示)的概念属性和关系体系;

Terminology为术语学,内容主要给出某一概念的本质属性或定义属性集合.

What is an Ontology?

Tom Gruber <gruber@ksl.stanford.edu>

Short answer:
An ontology is a specification of a conceptualization.
The word "ontology" seems to generate a lot of controversy in discussions about AI. It has a long history in philosophy, in which it refers to the subject of existence. It is also often confused with epistemology, which is about knowledge and knowing.

In the context of knowledge sharing, I use the term ontology to mean a specification of a conceptualization. That is, an ontology is a description (like a formal specification of a program) of the concepts and relationships that can exist for an agent or a community of agents. This definition is consistent with the usage of ontology as set-of-concept-definitions, but more general. And it is certainly a different sense of the word than its use in philosophy.

What is important is what an ontology is for. My colleagues and I have been designing ontologies for the purpose of enabling knowledge sharing and reuse. In that context, an ontology is a specification used for making ontological commitments. The formal definition of ontological commitment is given below. For pragmetic reasons, we choose to write an ontology as a set of definitions of formal vocabulary. Although this isn't the only way to specify a conceptualization, it has some nice properties for knowledge sharing among AI software (e.g., semantics independent of reader and context). Practically, an ontological commitment is an agreement to use a vocabulary (i.e., ask queries and make assertions) in a way that is consistent (but not complete) with respect to the theory specified by an ontology. We build agents that commit to ontologies. We design ontologies so we can share knowledge with and among these agents.

This definition is given in the article:

T. R. Gruber. A translation approach to portable ontologies. Knowledge Acquisition, 5(2):199-220, 1993. Available on line.

A more detailed description is given in

T. R. Gruber. Toward principles for the design of ontologies used for knowledge sharing. Presented at the Padua workshop on Formal Ontology, March 1993, to appear in an edited collection by Nicola Guarino. Available online.

With an excerpt attached.

3楼猿人提供的资料清楚地说明本体是一个概念化项目：包括词汇的正式定义，概念的属性、属性值和相互关系的正式规定或描述。目的是为知识代理(agent)的应用程序提供共享性、可重复应用性知识库，以保证代理之间的应用程序的知识库相互一致。


我在一篇文章中准备应用这段论述，[U][B]请猿人提供具体的应用地址。谢谢！[/B][/U]
