Abstract: A digital ink processing system, method, and program are provided that are capable of presenting, to a user, useful and highly relevant information as a search result when a search is performed using digital ink. A processor included in a tablet enables a pointing operation of an electronic pen relative to a stroke or strokes. The processor, after enabling the pointing operation of the electronic pen, performs a search for content related to a semantic attribute of the stroke or strokes pointed at, or requests an external server to perform the search. The processor performs control so as to display the related content retrieved by the search on a display with the stroke or strokes.
