Abstract: An online knowledge verification system, method and software system product provides self-generating community-based knowledge certification. The system can be web-based and includes an infrastructure that allows users to identify and import into the system information descriptive of virtually unlimited content media for which knowledge certification can be established. The system includes a Question Preparation Engine by which questions and answers for an identified content medium are prepared for supporting the certification process. A Question Judgment Engine permits users to provide endorsement scores for the value of questions provided by other users for each content medium. Testing Engines are provided for testing the knowledge of users, using the prepared questions and answers having sufficient endorsement from the community and providing certificates for users who pass the tests for that particular content medium.
