StumbleUpon churns through the Internet helping users discover articles, media and images, based on their areas of interest and the user’s thumbs up and thumbs down rating of already-seen content. More than 25 million people turn to StumbleUpon to be informed, entertained and surprised by content and information recommended just for them. In addition, more than 75,000 brands, publishers and other marketers have used StumbleUpon’s Paid Discovery platform to tell their stories and promote their products and services.
To cater to its international audience, Stumble Upon uses Rosette Language Identifier to make sure English users see English content and Chinese users see Chinese content, etc. For languages without reliable spaces between word–such as Chinese, Japanese, and Korean–Rosette Base Linguistics finds the words and normalizes them to enable more accurate and faster search results.
