The OpenDover Drupal module is built for version 6 of the Drupal Content Management System. This module will only work on websites based on the Drupal 6 Content Management System.

More information about how OpenDover can be used inside other systems will be released on a future date (until then you can use the OpenDover Drupal module as guidance or use the contact form here to hire us to implement a module for your situation).

More information about Drupal can be found here: http://www.drupal.org. If you need additional help with setting up your OpenDover module then you can get professional support via our contact form here.

To install the OpenDover module you need 3 things:

• The OpenDover module (which you can download here)
• An OpenDover API key (which you can create here)
• The RDF module (which you can get here)

To install the OpenDover module inside Drupal you have to uncompress the contents of the OpenDover package and the RDF package inside your sites modules directory (e.g. /sites/all/modules or /sites/yourwebsite.com/modules). Then log in to your website with the admin account and enable the modules on the modules page (e.g. http://www.yoursite.com/admin/build/modules). For the installation instructions of RDF, see the RDF module install instructions, this page will only discuss the OpenDover installation instructions.

The OpenDover module then is installed and you are able to configure the module on the OpenDover configuration page (e.g. http://www.yoursite.com/admin/settings/opendover). On this page you will have to fill in the OpenDover settings.

The Service Url setting is filled in automatically and intended for specific use cases, so you don’t need to change this setting.
In the license id field you have to fill in your OpenDover API key (which you can create here).

Then you have to enable OpenDover module for a content type. Per content type you can enable the OpenDover module, select a taxonomy that will be used as “base tags” for your sentiment analysis (read on for a more detailed description of the base tags concept) and a field that contains the “author” of the node.

The OpenDover module sends the Drupal node to the OpenDover service for processing after the node has been inserted/updated. The sentiment analysis is based on the selected taxonomy. This taxonomy acts as a set of “base tags”. Whenever one of the base tags occurs in the node text, the OpenDover service will search for sentiment words in the same sentence and will use these sentiment words to determine the sentiment of this particular base tag.

The OpenDover module also contains a block that allows you to select an OpenDover subject domain. This subject domain is used to select a sentiment word vocabulary. You should try to select a vocabulary that is closest to the subject of the articles that you want to be analyzed, in order to increase the quality of the sentiment analysis.

The outcome of the analysis is automatically shown on the node view page (see the example below).
