Documents are widely used in our information-rich society. The proposed research streamlines the transition between paper documents and electronic documents, contributing flexible and general techniques for converting the information in scanned paper documents into electronic form. One proposed project develops new methods for representing the decisions that are made by document recognition systems. An explicit representation of decisions makes it easy to determine the causes of recognition errors, and supports automatic optimization of recognition algorithms. The second proposed project improves document processing by combining an analysis of document text with an analysis of document figures. The approach will be tested on a document classification problem: identify which technical documents are relevant for maintaining a biomedical database. The third proposed project develops methods of using external data to validate and correct recognition results. For example, an internet search can be used to verify information recognized from a scanned business card, and to correct incorrectly-recognized digits in a telephone number.

文档在我们信息丰富的社会中被广泛使用。 拟议的研究简化了纸质文档和电子文档之间的转换，提供了将扫描纸质文档中的信息转换为电子形式的灵活且通用的技术。 一个拟议的项目开发了新的方法来表示文档识别系统做出的决策。 决策的显式表示可以轻松确定识别错误的原因，并支持识别算法的自动优化。 第二个提议的项目通过将文档文本分析与文档图形分析相结合来改进文档处理。 该方法将在文档分类问题上进行测试：确定哪些技术文档与维护生物医学数据库相关。 第三个拟议项目开发使用外部数据来验证和纠正识别结果的方法。 例如，互联网搜索可用于验证从扫描的名片中识别的信息，并纠正电话号码中错误识别的数字。
