Wikipedia is one of the most popular internet encyclopedias, being based on an open source platform and a huge community that is posting new information allowing every registered member to post or edit articles. Because Google is the most powerful search engine on the internet it was obvious that the company needed to include Wikipedia's information into the Google OneBox, another important reason being represented by the PageRank owned by the encyclopedia, currently placed on the 8th position.

Although Wikipedia's founder announced some time ago that the company is looking to produce a high-quality search engine that will be able to challenge Google's technology and become one of the most powerful services in the internet world, the search giant decided to include their results into the OneBox feature, a function that displays most relevant information according to the keyword entered by the user.

"Google has quietly added a new OneBox feature that highlights articles from Wikipedia. All you need to do to is tack on the word "info" or "information" at the end of your query and Google will put a large Wikipedia link at the top of the results page. Your search keywords and the Wikipedia article title need to match up exactly, otherwise the Onebox links don't show up.
As Wikipedia's power and brand rise, Google is going to dig deeper into the citizen-edited encyclopedia. Google loves frequently updated information so the fit is perfect. This will occur even as Wikipedia founder Jimmy Wales readies a Google competitor. While this OneBox is not a search engine for Wikipedia, it sure comes close. There's nothing to stop Google from going further and building a Wikipedia search engine and I suspect they will," Micro Persuasion mentioned in a blog post.

If you want to test the new feature included into Google Search, all you need to do is type "info" before your keyword. For example, "info Softpedia" sustains that Softpedia "is a site that indexes information and provides downloads for many games, drivers, mobile phones…"
