Hvad er det semantiske web? (web2.0 er bare et lille hik)
“Semantic Web” er af mange udråbt som det næste store og nødvendig. Web2.0 er bare et lille hik i forhold til de mulighed der ligger i det semantiske web. Hvis visionen altså bliver til noget. Som så meget andet findes der mange definitioner og visoner om hvad det kan blive til, men her er et godt bud :
- The Semantic Web is not just a single Web.
There won’t be one Semantic Web, there will be thousands or even millions of them, each in their own area. They will connect together over time, forming a tapestry. But nobody will own this or run this as a single service.
- The Semantic Web is not separate from the existing Web.
The Semantic Web won’t be a new Web apart from the Web we already have.
It simply adds new metadata to the existing Web. It merges right into the existing HTML Web just like XML does, except this new metadata is in RDF.
- The Semantic Web is not just about unstructured data.
In fact, the Semantic Web is really about structured data: it provides a means (RDF) to turn any content or data into structured data that other software can make use of. This is really what RDF enables.
- The Semantic Web does not require complex ontologies.
Even without making use of OWL and more sophisticated ontologies, powerful data-sharing and data-integration can be enabled on the existing Web using even just RDF alone.
- The Semantic Web does not only exist on Web pages.
RDF works inside of applications and databases, not just on Web pages.
Calling it a “Web” is a misnomer of sorts — it’s not just about the Web, it’s about all information, data and applications.
- The Semantic Web is not only about AI, and doesn’t require it.
There are huge benefits from the Semantic Web without ever using a single line of artificial intelligence code. While the next-generation of AI will certainly be enabled by richer semantics, is not the only benefit of RDF. Making data available in RDF makes it more accessible, integratable, and reusable — regardless of any AI. The long-term future of the Semantic Web is AI for sure — but to get immediate
benefits from RDF no AI is necessary.
- The Semantic Web is not only about mining, search engines and spidering. Application developers and content providers, and end-users, can benefit from using the Semantic Web (RDF) within their own services, regardless of whether they expose that RDF metadata to outside parties. RDF is useful without
doing any data-mining — it can be baked right into content within authoring tools and created transparently when information is published. RDF makes content more manageable and frees developers and content providers from having to look at relational data models. It also gives end-users better ways to collect and manage content they find.
- The Semantic Web is not just research. It’s already in use and starting to reach the market. The government uses it of course. But also so do companies like Adobe, and more recently Yahoo (Yahoo Food is built on the Semantic Web). And one flavor of RSS is defined with RDF. Oracle has released native RDF support in their products. The list goes on…
