Abstract:
A method for choosing documents of interest from a collection of documents, comprising:(a) determining an initial selection criterion; (b) applying the initial selection criterion to each document in the collection, to generate a rank-ordered list of documents; (c) if further refinement of the list is desired, evaluating a subset of the documents on the list to determine whether each document in the subset is relevant; (d) modifying the selection criteria by at least one of: adjusting weights assigned to each element of the selection criteria in the prior iteration, removing elements of the selection criteria from the prior iteration, and adding elements to the selection criteria, based upon features of the documents determined to be relevant; (e) applying the modified selection criterion to each document in the collection, to generate a new rank-ordered list of documents; (f) repeating the steps of (c), (d), and (e) until classification is sufficiently accurate for use.
