Document search and retrieval system with partial match searching of user-drawn annotations |
摘要 |
<p>In summary there is disclosed a document browser for electronic filing systems, which supports pen-based markup and annotation. The user may electronically write notes (60-64) anywhere on a page (32, 38) and then later search for those notes using the approximate ink matching (AIM) technique. The technique segments (104) the user-drawn strokes, extracts (108) and vector quantizes (112) features contained in those strokes. An edit distance comparison technique (118) is used to query the database (120), rendering the system capable of performing approximate or partial matches to achieve fuzzy search capability. <IMAGE></p> |
