A lot done more to do
Web 0 infinite eyeballs
Web 1.o Transactions
Web 2.0 Participation
Data INTEGRATION hasn't changed much really; cleverer techniques but bascially a brute-force approach

Web 3.0 (aka Semantic Web) is coming as the marketplace expects and demands it: question is whether it is more of the same market-hyped activity or a truly innovative game-changing phenomenon!

UNDER-THE-HOOD
IT'S A DATA PROBLEM
DUMB DATA with LINKED PAGES not LINKED DATA

Smart linked data is created by putting structure on text where there is none. There are three main approaches: Folksonomic, Taxonomic, and Ontological
Folksonomic classifications: Created by users using tags to annotate and categorize content.If enough people tag content, the wisdom of the crowd identifies concepts. It gives a statistically inferred relationship!

Relationships are created which can then be linked across web pages. Folksonomies are relationship light
Taxonomic classifications: Experts describe a thing or concept in a hierarchical tree with parent/child relationships. Hard to merge concepts through trees!
Ontological classifications: Are taxonomies with rules and are graph basedLots of possible relationships not just parent/childConcepts can be more easily joined with graphs

The web of linked data is gathering speed and can be easily traversed from one repository to another
DERI's Research Focus
DERI's research vision is to create advanced technologies enabling the semantic web in a world of interconnected data and knowledge
Interconnected
Universal
All encompassing
Enable global and local collaboration
The right information for the right people at the right time
DERI's Industry Oriented Research
DERI's has a good mix of MNCs, Irish SMEs, and start-ups partners: ISA members and MHC clients:
