Thinkpedia is a new way to navigate and explore the contents of Wikipedia. It is what we call a "Visual Wiki". Thinkpedia usesSemanticProxy in order to extract semantics out of Wikipedia articles, which are then shown in an interactive visualization which is created with Thinkmap.

The visualization is displayed along with the Wikipedia article, providing a focus plus context view. The thickness of the edges in the visualized graph corresponds to the relevance of the connected items. A range slider at the bottom of the application can be used to filter the graph according to this relevance.

Semantic Book Suggestions is a mind-bending combination of Calais, Wikipedia and Amazon. Enter a search term, the results are retrieved from Wikipedia, analyzed by Calais and then relevant selections from Amazon are presented. Take the time to play with this a bit - it's worth it. Also, make sure to click on the gray items on the left to see the drop-down menus.
