Social web

Social Web

  • Recent phenomenon on the Web

    • A new generation of Web

    • Most significant aspect of Web 2.0

  • Mass user participation

  • User activity

    • People Connect, Socialize and Interact

  • User-generated Contents

  • Easy to understand / use

Social web limitations

Social Web Limitations

  • Unstructured data

    • Unclear Semantics

    • Machines do not understand

    • Information processing/retrieval difficult

  • Lack of Interoperability

    • Lot of data locked in closed “Data Silos” or

      “Walled data gardens”

  • Lack of Standards

Semantic web

Semantic Web

  • Sir Tim Berners-Lee (inventor of the Web)

    “.. an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation..”

Scientific American (2001)

NEA-JC, 2008, Tokyo


Semantic web explained

Semantic Web (explained)

  • Web of Data

  • Giant Global Graph (GGG)

GGG - Web of Data

WWW – Web of Documents

NEA-JC, 2008, Tokyo


Semantic web explained1

Semantic Web (explained)

  • Data Modeling and Knowledge Representation

    • Machine understandable Semantics

  • Ontology

    “.. an explicit specification of a conceptualization”

    • modeling of the objects, concepts, entities, relationships that exist in the area of interest

Gruber (1993)

NEA-JC, 2008, Tokyo


Ontology

  • Consensus

  • Common formats

  • Standard Vocabulary

  • Interoperability

OWL

(web ontology language)

SPARQL query language

Resource Description Format

Microformats

RDFa

MIT

Linked Data browsers

Gene ontology

NEA-JC, 2008, Tokyo


Challenges for semantic web

Challenges for Semantic Web

  • Ontology creation is difficult

  • Global consensus is difficult

  • Difficult to understand and use for ordinary people

  • Lack of incentive / motivation

    • Lack of enough Data and Applications

NEA-JC, 2008, Tokyo


Semantic web chicken or egg

Semantic Web “Chicken or Egg”

Data first or Applications first

NEA-JC, 2008, Tokyo


Social semantic web

Social Semantic Web

  • Social Web + Semantic Web

    • Complement each other

    • Semantic Web

      • Machine understandable structure

      • Interoperability standards

    • Social Web

      • Easy-to-use platforms

      • Consensus thru Social interaction / collaboration

  • Combining the two cultures (Web 3.0 ?)

    • Semantic Wiki

    • Semantic Blog

    • Semantic Tagging

    • Ontology from folksonomy….. etc

NEA-JC, 2008, Tokyo


Stylid

StYLiD

  • Structure Your own Linked Data

    http://www.stylid.org

  • Social Web platform

  • Share a wide variety of Structured Data

    • Define your own Concepts (with attributes)

    • Easy for ordinary people

  • Publish on the Semantic Web

    • Exploit the structured data for useful applications

Conclusion

Conclusion

  • Social Web and Semantic Web

    • Developed independently

    • Weakness of one Strength of another

  • Social Semantic Web

    • Combine the two cultures

  • StYLiD

    • Social platform to share Semantic Web data

  • Effective integration not easy

    • Disadvantages creep in with advantages

  • Proper coordination between the two communities necessary
