4. The method as claimed in claim 1 , wherein said constructing comprises: determining, from said source domain, a set of bases for reconstructing said abbreviated text document examples; and, determining a set of classifiers for classifying said reconstructed abbreviated text document examples.
1. A method for processing documents comprising: constructing, via a programmed processor device, a hidden feature space from one or more text document examples of a source domain, said one or more text document examples tagged with one or more labels of a source domain label space; and, simultaneously training one or more classifiers for use in classifying text documents, said classifiers trained on said one or more text document examples and said hidden feature space; receiving, at said processor device, one or more abbreviated text document examples from a target domain; reconstructing, at said processor device, said abbreviated text document examples of said target domain based on said constructed hidden feature space; and, predicting the labels of said abbreviated text document examples based on the reconstructed target domain text document examples and said one or more trained classifiers.
