Automatic Index Creation for Handwritten Notes.

Abstract

This paper describes a technique for automatically creating an index for handwritten notes captured as digital ink. No text recog-nition is performed. Rather, a dictionary of possible index terms is built by clustering groups of ink strokes corresponding roughly to words. Terms whose distribution varies significantly across note pages are selected for the index. An index page containing the index terms is created, and terms are hyper-linked back to their original location in the notes. Further, index terms occurring in a note page are highlighted to aid browsing.
