Details

• What
  • An application that can integrate web resources about semantic web research

• Who
  • Users are researchers
  • Start from internal users (inside the group)? Probably not. Based on past experience, it is even hard for SW researchers to contribute to a semantic web site.
  • Information providers: most of information shall be collected by programs
  • Most of users will NOT contribute a lot.
  • May follow the pattern of DBLP

• Why
  • Major challenges to a successful semantic web application: Scalability and User Interface
  • The semantic portal application in our mind will address the both challenges
    • As a proof-of-concept application
    • Also of some educational value

• How
  • What matters
    • Presentation
    • Organization (of content)
    • Analysis (of data), e.g., statistics, ranking
  • Behind: a tripe store
    • Scalability may be archived by (offline) computing materialized views (e.g. transitive closure)
      • Is it complete for all queries?
      • Update issue (incremental reasoning)
      • What expressivity of RDF is allowed for efficient materialization?
  • Some unique features?
    • e.g., citation work, research topic ontology

• Examples
  • Planet RDF
  • DBLP
  • DBLife
  • Ping the Semantic Web
