On the 20th march 2009 Byelex reveiled the outline of here latest product OpenDover at the Drupaljam in Enschede, Holland. OpenDover is a powerfull webservice that can be called via an opensource Drupal module, in order to tag large quantities of text containing opinions on all sorts of subjects. At the same time OpenDover will determine of each text the overall sentiment, i.e. Is the text positive or negative with respect to the subject of that text.

With OpenDover webdevelopers are now able to add sentiment to their content, without the painstaking task of going trough vast amounts of reviews, blogs or news articles themselves.

OpenDover will be presented to the Drupal community first, via a module that can be plugged-in into a Drupal CMS, so that each document created in a Blog, or review page is automatically tagged based on the sentiment the document contains.

The Presentation on OpenDover can be found on Slideshare.
