What is Semantic Web? Web of data
precise, structured information on: Objects on the web and in the real world Relations between them
Resource Description Framework (RDF) triples in the form of (subject, predicate, object) graph with objects (nodes) and relations between them
Easy Integration of Data Data of different nature (FOAF, SKOS, RSS, …)
SIOC – model of data – for social media sites
Online communities Online community sites:
Provide a valuable source of information May contain rich meta-information Many sites discussing complementary topics
But are isolated from one another: They are like islands without connecting bridges
SIOC SIOC provides methods for interconnecting discussion
methods such as blogs forums mailing lists Wikis
Add more value Let other sites know more about the structure and
contents Make more use of tagging and semantic metadata
