Raw digital ink is informal and unstructured. Its editing, especially its selection, is often inefficient. In this paper, we present approaches to structuralize raw digital ink as multiple hierarchies to facilitate its selection. First a link model is built to organize ink as a mesh-like structure. Based on the link model, the isolated stroke groups form patches. In each patch, textual and graphical areas are separated. Then, each textual area is segmented into text lines, and each text line is partitioned to words. We also design gestures for selecting structured ink. Experiments showed that our ink-structuralizing approaches are effective and selecting structured ink by our gestures considerably outperforms selecting raw ink.
