MediaWiki extractor

MediaWiki extractor allows you gather topics and associations from various large knowledge repositories such as Wikipedia. MediaWiki extractor reads the XML dump of MediaWiki page and creates a topic for the page. Page content is attached to the topic as a text data occurrence. The extractor is started with File > Extract > MediaWiki extractor. You can extract data from local XML files or directly from MediaWiki site using export URL of the page. For example the export URL of this page is

http://www.wandora.net/wandora/wiki/index.php?title=Special:Export/MediaWiki_extractor

Postprocessing MediaWiki extracted topics

The MediaWiki extractor does not process the content of extracted pages. However it is possible to create associations out of page content using another tool in Wandora. Context menu has a tool called Topics > Associations > Find associations in text datas... that can be used to extract associations out of text data. The tool requires type and scope of processed text data, topic's role in new associations, and regular expression used to recognize topic names in text data.
