A system for information retrieval on the internet requests the information providers, such as web site administrators, to provide characterizing data in the form of questions a user may ask in looking for the information (314). The characterizing data (404) is stored in a database along with the destination data (406) that indicates where the information may be found on the internet. An information seeker may then enter a query in the form of a natural language question (204). The question in the query is then matched against questions stored in the database (608). If there is a match, the associated destination data is employed to retrieve information for the information seeker (610). Both the information seeker and the information providers may also furnish filter values (408, 410) to filter the information retrieved in order to allow the system to provide only the most relevant information to the information seeker.
