Abstract

An apparatus and method for searching a handwritten memo, which is input by a user using a digital pen interface, for a word corresponding to the user's query. The apparatus includes a preprocessing unit which removes unnecessary portions from digital ink data of an input query phrase and an input memo to reduce an information amount, a feature extraction unit which extracts a feature vector from the digital ink data having the reduced information amount, and a query searching unit which searches the memo for a portion matched with the query phrase in units of segments. Therefore, an accurate result can be obtained quickly when an existing memo or document is searched for desired content by inputting a query phrase using a digital pen.
