Data & Machines, Metadata Based 数据及机器, Metadata为基础
- Metadata is added to Web resources
Metadata被加入成为网络资源- they describe properties of the resource
它们描述资源的内容
- they describe properties of the resource
- Metadata vocabularies (ontologies) can be developed
可以开发Metadata词语 (ontologies)- makes a logical reasoning on the metadata possible, e.g.
使在metadata的逻辑推理可行, 如:- “if this property is true, then that property is true…”
“假若这项内容是真确的, 那么那项内容就是真确的…” - “this property is that same as that property…”
“这内容是等同那内容的…” - etc.
等
- “if this property is true, then that property is true…”
- makes a logical reasoning on the metadata possible, e.g.
- Applications are based on analysing the metadata
应用是依据把metadata分析- e.g., search engines
例如: 搜寻器
- e.g., search engines
- This is the area of the Semantic Web
这是语义网的区域- “an infrastructure for reasoning on the Web”
“一个可以在网上推理的基础设施”
- “an infrastructure for reasoning on the Web”
