问题
I want to write a basic semantic web crawler using Python, I know that semantic apps use RDF files, but what else? I have some Python RDF modules installed and I started learning how they work.
Could you introduce me to the technologies and techniques used in a semantic application?
回答1:
The next things you might want to learn are:
- embedding samantic data in HTML - RDFa, microformats, microdata. Some stats: microformats and RDFa deployment across the Web via DAM.co.uk:
- querying RDF data - SPARQL
- most popular ontologies currently in use
- list of available SPARQL endpoints
You can find some examples of SPARQL queries here. Another notable Q&A resource is semanticweb.com.
