The UNL EOLSS Interface was developed in Java both as a web-based and a stand-alone application.
Download the stand-alone version (the files should be extracted to the same folder. In order to open the system, run the file Eolss.jar - Java 6.0 required).
The system comprises two windows: the left one is the navigation window; the right is the exhibition one. There are three different types of navigation: EXPLORE, DISCOVER and SEARCH.
In the EXPLORE VIEW (Figure 1), we present a tree structure, both expandable and collapsible, representing the Table of Contents. It is the best navigation strategy for those who already know the Encyclopedia internal structure and look for fast and direct access to the EOLSS entries. Entries, when activated, lead directly to the Encyclopedia articles, which can be viewed in the right window.

In the DISCOVER VIEW (Figure 2), we present a hyperbolic tree structure, a navigable graph interlinking titles, keywords, authors, institutions, cities and countries. The nodes are shown on demand in different colors in the left window. The default view displays only titles, but the view can be customized by the option SHOW NODES in the menu bar. Nodes can be shown either in UNL or in any available language (to be set by the option LABEL NODES). Every node is a hyperlink, either to other node or to an HTML document, to be displayed in the right window

Finally, the SEARCH VIEW performs the search in the EOLSS search engine and displays the results as a new navigable hyperbolic tree, where search can be refined as nodes are again hyperlinks to the articles of EOLSS.
