25. The computer-readable medium according to claim 18 , wherein said receiving step receives information having been previously parsed into lines.
18. A computer-readable storage medium having a program stored thereon for associating user input with parsed information, said program when executed enables a computer to perform: receiving parsed information; determining raw features of at least one of component portions of the received parsed information; receiving user input designating a hierarchical level of said at least one of component portions of the received parsed information with respect to other component portions based on the determined raw features; associating said user input with the at least one of the component portions of said received parsed information; storing at least said association in a storage medium; 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 storing and training steps further comprise: storing multiple associations linking user input to multiple component portions of the parsed information, respectively; and training model parameters of an algorithm for determining the hierarchical levels of component portions of parsed information, using said multiple associations.
