Abstract: There is provided a method (100) for performing data capture in an unlabelled document based on a labelled document, wherein the labelled document contains one or more elements each labelled with respect to a field. The method comprises: determining (S110) one or more anchors, wherein an anchor comprises a pair of points that match between the labelled document and the unlabelled document; generating (S120) an overall kernel using the determined one or more anchors; and identifying (S130), using the overall kernel in a kernel machine, one or more elements to be captured in the unlabelled document, wherein the one or more elements to be captured correspond in field to the one or more labelled elements contained in the labelled document.
