OHI Tool


The OHITool extension is an extension used in a Virtual Research Environmen based on Semantic MediaWiki and allows reaserchers to carry out Qualitative Analysis of social interaction using Objective Hermeneutical methodology. The extension particularly has been tailored to be use for classroom interaction analysis.

It was developed within the research project SMW-CorA and funded by the DFG.


Download the zip file and extract it to the folder of your MediaWiki installation, unter the folder extensions.



Template:TNT This extension requires MediaWiki, Result Formats and Tabs to be installed first.

Please edit the file LocalSettings.php and add the following line:

require_once( "$IP/extensions/OHI/OHI.php" );

The extension will be installed under the Section Other special pages of Special:SpecialPages, under the name Objective Hermeneutic Interpretor Tool.



This is a brief introduction on how to use the OHITool. A more detailed guide will appear on this page in the near future. Important. After the installation, in the extension folder, there is a folder OHI/resources/templates. A .XML file contaning templates, forms and semantic properties could be automatically created using Import procedure of MediaWiki.
