Semantic Wiki metadata usage

How is (meta)data used?

Trust

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

Navigation

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

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

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)

Evaluation of Wikis

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

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.
