Abstract
A computer-implementation method for dataless contextual targeting includes the following steps. First, automatically crawling noisy labeled corpora from one or more sites using a category mapping from first categories to second categories. Second, applying one or more statistical methods to automatically mine representative keywords for each of the first categories from the noisy labeled corpora. Applying dataless classification learning to induce a text classifier with the automatically mined representative keywords and unlabeled web pages as input.
