Usually from YOU(as data is created/gathered socially)

Data is extracted and transformed into linked data using patterns and/or natural language processing techniques and/or machine learning techniques

Where do we do with the data we extract from web sites?

Describe it using an ontology or many ontologies

Frbr ontology

Foaf ontology

Event ontology

Link to other datasets

Create the ontology

Develop a Semantic Web Application

Extract linked data into a semantic repository

Establish a SPARQL endpoint

Choose a domain

The long and winding road you have to follow
