Description: The World Wide Web has become a vital supplier of information that allows organizations to carry on such tasks as business intelligence, security monitoring, and risk assessments. This paper presents a first prototype for a meta approach to fact seeking. A meta engine sends a user's question to several fact seeking services that are publicly available on the Web and analyzes the returned results jointly to identify and present to the user those that are most likely to be factually correct. The results of the evaluation on the standard test sets widely used in prior research support the evidence for the following: 1. the value-added of the meta approach: its performance surpasses the performance of each supplier, 2. the importance of using fact seeking services as suppliers to the meta engine rather than keyword driven search portals, and 3. the resilience of the meta approach: eliminating a single service does not noticeably impact the overall performance.
