Semantic Wiki metadata usage

How is (meta)data used?

[edit] Trust

• Can trustworthiness of article content be determined from the article metadata? (tomorrow)

[edit] Navigation

• alternative view on the data: graphs (today)
• Show predicates for an instance (as subject/as object) (today)

[edit] Search

• Allow precise search for specific attributes (area of a country) (today)
• Challenge: Formulation of complex queries by non-experts (open)
• Assistants for query formulation and refinement. (tomorrow)
  • These things exist outside semantic wikis.
• Personalized search (metadata of searcher, metadata of content) (tomorrow)
  • Example: Corporate Wiki
    • Managers have other informational needs -- high-level results of controlling reports.
    • Employees working on the report need all detailed information
  • Example: Research group
    • Researchers enter their interest groups

[edit] Automated Content Generation

• generation of content (dynamic content) (today)
• Reasoning on content to generate new information (wikipages)
• Use metadata to generate individual views: Annotations can provide the necessary information for selecting the appropriate parts of the text. (tomorrow)

[edit] Evaluation of Wikis

• Use (meta)data in order to evaluate the completeness/quality of the complete wiki (including the text). (today)

[edit] External applications

• Can ontologies created by semantic wikis be trusted in the same way as data created by experts? -- This is connected to the general problem of trust in freely editable sources.
• What if tools make important decisions relying on such data?
• Technically it is possible: Almost all implementations of semantic wikis provide export functions.
• remark from the "creation group": We want the live data, not a copy.
  • Applications using live data of a semantic wiki (tomorrow)
• Is there already a real-world external application?
  • One answer: This is not a fair question -- just wait until there are enough mature semantic wikis out there which can provide really interesting data.
  • Data generated by Christoph Lange's mathematical semantic wiki _will_ be used by several outside applications.
