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.

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



Template:TNT This extension requires Semantic MediaWiki, Semantic Result Formats and Header 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 Special:Import procedure of MediaWiki. The import will create also a complet exaple of a transcript, in the main namespace, under the Neu_Ethik_Klasse6_Fremdsein_apaek02152 name.

In order to start a new transcript, please call special page Formular:Erhebungsmaterial_Metadaten, if your wiki is in German, otherwise call Form:Erhebungsmaterial_Metadaten (for English). After you collect the transcript data and save the formular, you should see the following interface:

Known issues

  • This tool is usually required in German space, due the fact that it was a genuine German idea. This is the reason that properties, templates

and interface is in German. For the next version, we plan to have an English version also.
