26. A computer for associating user input with parsed information comprising: means for receiving parsed information; means for determining raw features of at least one of component portions of the received parsed information; means for receiving user input designating a hierarchical level of said at least a component portion of said parsed information with respect to other component portions based on the determined raw features; means for associating said user input with the at least one of the component portions of said received parsed information; means for storing at least said association in a storage medium; and means for training model parameters of an algorithm for automatically determining the hierarchical levels of component portions of parsed information from said raw features, using said association; and wherein said means for storing and means for training further comprise: means for storing multiple associations linking user input to multiple component portions of the parsed information, respectively; and means for training model parameters of an algorithm for determining the hierarchical levels of component portions of parsed information, using said multiple associations.
