eyePlorer is an online research tool that I think is worth a look. I feel that there are many learners who will probably find it helpful.

Note: If you do not read German, please don't be put off when you discover that the website is in German. It appears that English is the default language of the application!

In short...

• eyePlorer searches Wikipedia for specified topics and displays search results graphically.
• Facts about a topic are represented by “eyespots” on a circular graph.
• Each eyespot is a heading.
• If you click on a heading/eyespot, you open a text box containing a summary sentence about it.
• These sentences can be dragged and dropped onto a notepad and then conveniently copied to the computer’s clipboard for use elsewhere.
• Double-clicking on an eyespot connects that heading with other headings to show that they are related in some way.
• Clicking on a line between two headings, opens a sentence that summarizes the relationship.
