Abstract
A system and method for detection of a list in ink input is provided. A detector is provided that may detect a list such as a bulleted or numbered list of items in ink input. A group of lines may first be selected as a candidate list. Indentation level clustering and bullet detection may then be performed to determine the structure of the list. Bullet detection may be performed by detecting bullet partners, which are pairs of lines at the same indentation level that may begin with bullet candidates with similar features. The features of the bullet candidates in a pair of lines may be used to determine the likelihood of whether the pair of lines may be bullet partners. Finally, the structure of the list may be determined, including the relationship among the list items.
