摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for searching a handwritten memo which is inputted by a user using a digital pen interface for a word corresponding to a user's query.

SOLUTION: The apparatus includes a preprocessing part which removes various kinds of unnecessary portions from digital ink data related to an input query phrase and an input memo to reduce an information amount, a feature extraction part which extracts a feature vector from the digital ink data having the reduced information amount, and a query searching part which searches a memo for a portion matched with the query phrase by units of segments. Thus, accuracy and promptness can be achieved when an existing memo or a document is searched for a desired content by inputting the query phrase with a digital pen.
