中文摘要： 蒙古文古籍文献是蒙古族传统文化的重要载体，也是中华民族文化遗产的重要组成部分。然而，蒙古文古籍文献作为不可再生的宝贵文化资源，大都被珍藏在博物馆、图书馆里，不允许随便翻阅，这不但影响了蒙古文古籍文献的利用与传播，还制约了少数民族文化的传承与发展。数字技术的飞速发展使得蒙古文古籍文献可以通过数字化的形式保存和共享，这为挖掘和利用蒙古文古籍提供了前提条件。本项目拟以具有代表性的蒙古文大藏经为对象，在识别方法与无识别方法相融合的技术框架下，从文字识别和词定位两个角度出发分别构建文本索引库和特征索引库，以实现蒙古文古籍图像的全文检索。为此本项目将重点研究单词图像恢复、自动文本标注、字元切分与识别、多特征组合表示与固定长度表示、多样例检索、多检索结果融合等关键问题。本项目的实施对挖掘和利用蒙古文古籍文献、繁荣和发展少数民族文化具有重要意义。

英文摘要： Ancient Mongolian documents is a kind of carrier for the traditional cultures of the Mongolian people. And they are also the important component of Chinese nation's cultural heritage. However, as a kind of non-renewable cultural resources, the ancient Mongolian documents are mostly protected in museums and libraries. So, it is difficult to make use of them. It not only influences the utilization and transmission for the ancient Mongolian documents, but also restricts the inheritance and development of the minority nationality's culture. With the development of digitization technique, more and more ancient Mongolian documents are converted into digital images so as to protect them as long as possible. And the digital images can be shared more conveniently. The above provides the precondition for mining and utilizing the ancient Mongolian documents. In this project, the Mongolian Tipitaka is considered as the research object. Our research framework is based on a combination strategy of the recognition-based method and the recognition-free method. The indexes will be constructed by the character recognition technology and the word spotting technology separately, which can realize the aim of retrieving the ancient Mongolian document images. Therefore, the key research contents include restoration and automatic text annotation for word images, representation by the mixed features with fixed-length, multi-instances retrieval, data fusion for multiple ranking lists and so on. The project can play a very important part in mining and utilizing the ancient Mongolian documents. Moreover, it is very meaningful for promoting and developing the culture of minority nationality.
