The nodes and edges of the graph are associated with respective sets of features, the edge features distinguishing between intra-page and cross-page edges. A trained first model jointly predicts class labels for page objects, based on node and edge features. Page labels for the pages may be predicted, based on the page object predictions, optionally enforcing a constraint, such a maximum of one class label for a given class, per page. The pages can be assigned a respective category, based on the predicted classes of the page objects and respective features. Information based on the predictions is output, such as one or more of the page object class labels, the page labels, and information based thereon.
