A method and apparatus for establishing a degree of confidence that a real world object correctly represents a string is provided. The method includes receiving a string in a context. The string can then be related to a real world object with a degree of confidence based on a click log, link graph, redirect list, or object list. The object can be initially associated with a category or mapped to a category. Then, the degree of confidence can be raised if the category matches the context. If the category does not match the context, the degree of confidence can be lowered. An online service provider using the method can then determine what type of content to send a user based on the confidence level.
