1. An active learning system for classifying documents in a document collection as a member of one or more classes or subclasses, the system comprising: a processor being adapted to: select a document from the document collection; calculate at least two predicted classifiers, for at least one of the one or more classes or subclasses, each predicted classifier being calculated using a document information profile for the selected document, a current classifier associated with at least one of the one or more classes or subclasses, and a different coding decision selected from a set of possible user coding decisions that may be received from a user; determine a processing order for a subset of documents in the document collection that indicates an order in which the documents of the subset are to be scored; for each one of the predicted classifiers, calculate a set of scores for one or more documents in the document collection, at least in part, according to the processing order, wherein each score is generated for a document by utilizing the corresponding predicted classifier and a document information profile of the document to be scored; and in response to receiving a user coding decision, classify a set of documents in the document collection into one or more of the one or more classes or subclasses using a subset of the set of scores based on the predicted classifier that corresponds to the received user coding decision.
