1. A method of obtaining information of interest from a binarized document, the method comprising: storing information associating a plurality of different label aliases with a first label for first information of interest; storing in a nodal structure, information representing an expected relationship between objects of a first label alias in said plurality of different label aliases, individual objects of said first label alias being linked in said nodal structure to other objects, each of the linked objects being a character or character string, individual links in said nodal structure having a probability associated with the individual link; scoring a first portion of the binarized document against said nodal structure to determine scores for multiple label aliases; determining based on said generated scores if said first label alias is present in said first portion of the binarized document; and in response to determining that said first label alias is present in said first portion of the binarized document, extracting information from the first portion document corresponding to said first label alias.
