50 Awesome Semantic Apps for Educators

The semantic web has been touted as the next great frontier on the Internet. Teaching computers to understand how the human brain categorizes and thinks is at the heart of this concept and promises to open the doors to easier and more efficient access to information on the Internet. For educators, this means that information available to students is of a higher caliber than what is sometimes available with traditional web applications. While this field is just starting to grow, there are several applications available right now of which educators can take advantage. From web browsing to research to blogging to collaboration, these apps will provide a taste of what may be on the horizon with the semantic web in education.
