MotivationMotivationPeople want to share information on
the Web
Lets share Structured Data◦Model different types of data◦Semantics becomes explicit◦Effective information sharing and gathering◦Effective Search and Browsing◦Integrate/Remix data from various sources◦Interoperability among systems

ChallengesChallengesWide variety of information to share
◦ Long Tail of information domains (Hunyh et al. 2007)
Traditional database driven systems◦ Rigid and specific
Ontologies for the Semantic Web◦ Difficult to create◦ Not many popular ontologies◦ Difficult to search, understand and use
Not feasible to create new systems every time
Easy system for all general users◦ Mass participation
Multiple user perspectives, requirements and contexts

StYLiDStYLiDStructure Your own Linked Data
http://www.stylid.org
A Social Software platform ◦ Structured Information sharing
Freedom to define your own concepts ◦ Conceptualize and share any“thing”
Easy to use ◦ For any general user
Multiple Definitions◦ Consolidated by the system
Emerging popular concepts ◦ evolve incrementally

StYLiD◦ Sharing wide variety of Structured Data
Social software◦ Easy and flexible interface◦ Let users contribute freely
Consolidation of Multiple conceptualizations◦ Semi-automatic alignment of attributes
Ontology as by-product of information sharing
Supporting Linked Data◦ Formal machine understandable output
Future and Ongoing WorkFuture and Ongoing Work
SWKM 2008, Beijing, China 18
Incorporating robust schema alignment systems
Computing relations among concepts◦ Hierarchical / non-hierarchical ◦ based on Concept structure / Instance data
Consolidating concepts with different names
Disambiguation of concepts with same name
Plugins to utilize on structured dataExpose data through API / extended
