Semantic MediaWiki - Knowledge Management and Open Data Use Cases

1,165 views

Published on

Semantic MediaWiki (SMW) is a full-fledged, open source knowledge management system based on MediaWiki, the software used for Wikipedia. It enables wikis not only to manage textual information, but to define, store and retrieve data to be used inside the wiki (for querying, displaying, aggregating) as well as outside of the wiki. In can be used to produce Open Data, or to consume and re-use Open Data. Many Open Data initiatives lack the viewpoint of internal data monitoring, where SMW can play a vital part not only in identifying relevant datasets, but also in setting up procedures for identifying datasets to be published.

  6. 6. www.kdz.or.at Content Management vs. Wiki Control = CMS  Access control on different content types (Filesystem), Sharepoint, Drupal, Typo3, Joomla… Transparency = Wiki  Everyone can view/edit everything  Restrictions on actions (who can view/edit), not on content types (what)  Changes visible  Easy rollback Advantage: enables cultural change! 20.

  7. 7. www.kdz.or.at Strengths and Weaknesses of Wikis  Wikis are great for text…  easy to use, easy to edit  full text search  collaborative editing  categories to organise pages   Wikis have weaknesses for knowledge management!  no data, only text: 995 32  no relations, just links: Tbilisi —> Krakow  no querying of data  lack of structure leads to manual effort  manual edited lists (List of danube bridges, list of Autrian museums by city) 7

  11. 11. www.kdz.or.at Wikis and Data in 2015  extract structured information from Wikipedia and make this information available on the Web  free knowledge base that can be read and edited by humans and machines alike… central storage for the data that may be accessed by the client Wikis  lets you store and query data within the wiki's pages. Turns a wiki into a powerful and flexible knowledge management system. 20. April 2015 · Seite 11
