현대 사회에서 사물에 대한 정보를 얻는
가장 보편적인 방법은?

정보가 필요해!

= Annotation

슬프지만 저는 Annotation을
표현 할 수 없어요 ..

Typed Link :링크가 어떤 것인지 알 수 있음

Typed Link :링크가 어떤 것인지 알 수 있음
참조하고서술하고

Typed Link :링크가 어떤 것인지 알 수 있음
참조하고서술하고
두 페이지 사이의 의미를 파악 할 수 있음

Requirements for knowledge representation mechanisms
지식표현 메카니즘의 요구사항
Entity identity Relationship
Extensibility Vocabularies(Ontologies)
![Page 25: Social Semantic Web CH4. Adding Semantics to The Web(1)](https://reader034.fdocuments.us/reader034/viewer/2022042623/54c459854a79592c6b8b4587/html5/thumbnails/25.jpg)
Requirements for knowledge representation mechanisms
지식표현 메카니즘의 요구사항
Entity identity
웹상에서 존재하는 엔티티는 반드시 유일하게 식별되어야 한다.
![Page 26: Social Semantic Web CH4. Adding Semantics to The Web(1)](https://reader034.fdocuments.us/reader034/viewer/2022042623/54c459854a79592c6b8b4587/html5/thumbnails/26.jpg)
Requirements for knowledge representation mechanisms
지식표현 메카니즘의 요구사항
Relationship
엔티티들 사이의 관계는 관련 지식을포착하고 표현 할 수 있어야 한다.
![Page 27: Social Semantic Web CH4. Adding Semantics to The Web(1)](https://reader034.fdocuments.us/reader034/viewer/2022042623/54c459854a79592c6b8b4587/html5/thumbnails/27.jpg)
Requirements for knowledge representation mechanisms
지식표현 메카니즘의 요구사항
Extensibility
웹의 진화 및 적응성에는 고정된 스키마가 적당치 않다.

Requirements for knowledge representation mechanisms
지식표현 메카니즘의 요구사항
Vocabularies(Ontologies)
특정한 데이터의 교환과 표현에는이러한 방법에 대한 공통된 합의가필요하다.
