The web is a vast collection of data, such as text and images, but contains large numbers of duplicates - the same document or picture may be present many times. Even personal collections of information, such as the documents and digital photos people keep on their home computers, often have many versions of the same item. However, detecting such duplicates is not straightforward, as they may have been edited, or may, for example, be shown in different forms; for example, the quality of a photo may be reduced for display on a mobile phone. In this project we plan to detect such duplicates, and use the results to improve search and management of data.

Web是一个庞大的数据集合，如文本和图像，但包含大量的副本-相同的文档或图片可能会出现很多次。即使是个人收集的信息，如人们保存在家用计算机上的文档和数码照片，也经常有同一项目的多个版本。然而，检测这样的重复并不简单，因为它们可能已经被编辑，或者可能例如以不同的形式示出;例如，照片的质量可能被降低以用于在移动的电话上显示。在这个项目中，我们计划检测这样的重复，并使用结果来改善数据的搜索和管理。
