VIDI is a european project on analysing public discussion forums.
The official project page can be found at http://www.vidi-project.eu/.
This is the server running the analytical modules of the VIDI software developed at Jozef Stefan Institute; no content is hosted here except for instructions on how to install the VIDI toolbar. As a user, you typically do not need to install anything as the forum owner performs the installation for you. An exception to this is currently the index.hu page (see below).
