Extractor Cook Book

Requirements

• some knowledge of PHP or a similar object oriented language
• PHP CLI needs to be installed

Setup

• Download the code, or if you are familiar with SVN, you can use this direct link:
  svn co https://dbpedia.svn.sourceforge.net/svnroot/dbpedia/extraction dbpedia
• Run php extract_test.php to see if everything is working.

Developing

• You need to create an extra Extractor. The best way to start is to use extraction/extractors/Sample Extractor.php (pre-existing, but needs to be commented a little more elaborately)
• Copy the file; and rename the file, the class in the file, and the extractor id.
• Adjust extract_test.php
  • Rename the extractor class.
  • Change the articles, if necessary for testing.
• If you think your Extractor Class is finished, mail it to us.

Notes

• Extractors are subclasses of Extractor.php, which implements Extractor Interface.php.
• Extractor Container.php is a Wrapper.
