WikiSummarizer is an application designed by Context Discovery Inc. The application automatically summarizes the Wikipedia articles. The summaries consist of the most important content and keywords. The goal is to facilitate finding essential facts and identifying the relevant information across ALL articles so we can benefit from the wealth of facts collected in Wikipedia.
This service is a mash-up of Wkipedia, Flickr, and YouTube. It actually matches videos and images to Wikipedia entries. When you search something in Navify you will get results in three tab displays with related images and related videos included.
This service allows you to explore new places using Wikipedia entries. Just drag the map around and wikipedia articles will appear on the map as red points. Click on them to read the article.Or search using the search box.
Wikihood also uses Google Map services allowing users to geolocalise what they search for. When you type in a query in their search box you will get two kinds of results one is in the form of a map with placemarks and the second next to it is Wikipedia articles.
