Freeform digital ink annotation recognition

摘要

The present invention leverages classification type detectors and / or context information to provide a systematic means to recognize and anchor annotation strokes, providing reflowable digital annotations. This allows annotations in digital documents to be archived, shared, searched, and easily manipulated. In one instance of the present invention, an annotation recognition method obtains an input of strokes that are grouped, classified, and anchored to underlying text and / or points in a document. Additional instances of the present invention utilize linguistic content, domain specific information, anchor context, and document context to facilitate in correctly recognizing an annotation.
