    • 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.
    • 一种用于搜索由用户使用数字笔界面输入的用于与用户查询对应的单词的手写备忘录的装置和方法。 该装置包括:预处理单元,其从输入查询短语的数字墨水数据和用于减少信息量的输入备忘录中去除不必要的部分;特征提取单元,从具有减小的信息量的数字墨水数据中提取特征向量;以及 查询搜索单元,其以片段为单位搜索与该查询短语匹配的部分的备忘录。 因此,当通过使用数字笔输入查询短语来搜索现有的备忘录或文档时,可以快速获得准确的结果。
