2. Introduction Austria-Forum aims to: Overcome the identified problems in using online encyclopedias in education Provide information within a local Austrian context 3. Local Austrian context Local Austrian content vs. global Wikipedia-like content Different target groups of users Users with special interest in Austria get fine-grained information German chapter of Wikipedia does not provide such detailed information 4. Educational use of online encyclopedias Problems: copy&paste syndrome in combination with incorrect and unchecked information fragmentation of knowledge (acquisition of superficial knowledge) 5. Educational use of online encyclopedias Solutions: control the quality of published information support users in context sensitive searching and browsing of available information 6. Quality-inspected content Main goal: citable articles Correctness of articles is guaranteed Authors are authenticated with their real names Articles achieve a level of maturity and do not change any more Control the content, but allow openness and collaboration as well 7. Publishing process (1/4) Four key publishers A board of editors 70 well known Austrian experts in different fields A team of five employed editors Politically independent Community / users 8. Publishing process (2/4) Three main lexica AEIOU- an existing Austria-Lexicon Wissenssamlungen special lexica on special topics Community area Articles in the first two lexica are mainly contributed by key publishers and editors Volunteers / community can contribute as well 9. Publishing process (3/4) Figure 10. Publishing process (4/4) Users can edit / create new articles in the Community area Articles are reviewed by one or more editors When certain criteria are met, these are stamped as citable Citable: who wrote the article and when it was written Authors credited for their contribution Collaboration is enabled through: comments, discussions, new articles 11. Context-aware searching and browsing Content organized in hierarchical categories Category-sensitive searching and browsing Tag clouds Tag / metadata driven search Implementation based on JSPWiki 2.8 12. System overview 13. Structuring content (1/2) Two main categorizations in wikis: tag based categorization add a category tag to documents sub-paging a category must exist before creating a sub-page interlinking between category-pages and sub-pages is done automatically 14. Structuring content (2/2) Sub-paging in Austria-Forum: unlimited levels of categories and sub-categories (hierarchical) implemented as an extra feature Insert page plugin Visualization of the structured content paginating views of categories glossary based visualization of sub-pages available within a category 15. Retrieving content Information retrieval schema based on structural URLs and links Example: biography of an author URL: http://www.austria- lexikon.at/af/Biographien/Lorenz_Konrad Referenced through: [Biographien/Lorenz_Konrad] No relative linking schema: users always know in what context they find certain information 16. Tagging content Why include tagging? Enhance organization of information items Group related documents in tag-clouds Improve navigation and search Category pages have their own contextualized tag-clouds 17. Searching content Context-aware and metadata searching Within a category Spare users from excessive retrieval results Refine retrieval results through metadata Apache Lucene, field-data structure for metadata Full-text, tag / title search 18. Current status Launched in October 2009 90.000 information items (documents and multimedia content) Four key publishers Board of editors (40 at that time) Editorial team (5 members) Currently: ~ 130.000 information items 70 members of editorial board Attracts ~3500 users per day Community contributions - increased 19. Future work Popularize Austria-Forum Use it as a collaborative learning tool in schools and universities Project with NetBeans and SVN Research: Collecting and applying metadata (updates from APA Austria Presse Agentur) Mobile devices, e-books Interlinking and link control 20.
