Wikipedia is with no doubt the biggest online encyclopedia. Many people around the world use it to find the answers to their questions. Until very recently, the only downside were the search options. To search for something you had to type exactly a keyword that you were interested in. That was all you could do. However, some time ago with the help of Powerset’s technology, the search feature was drastically improved, and right now it resembles a lot more Google’s search feature. I must say that a reliable search function is very important, because many users have problems searching for various terms on many websites. The fact that the newest search technology breaks down keywords into related concepts enabling better search methods is thrilling and innovative.
