摘要:

词汇识别是历史文献分析中的一项重要识别任务。在大多数情况下,方法的开发和评估假设完美的分词。在本文中,我们提出了一个实验框架,量化的效果良好的分词的词发现方法在相同的无偏条件下取得的性能。该框架包括在分割上生成系统的失真,并从失真的数据集中检索原始查询。我们将框架应用于乔治·华盛顿和巴塞罗那婚姻数据集以及几种已建立的最先进的方法。实验允许单词识别方法的端到端性能的估计。

英文摘要:

Word spotting is an important recognition task in historical document analysis. In most cases methods are developed and evaluated assuming perfect word segmentations. In this paper we propose an experimental framework to quantify the effect of goodness of word segmentation has on the performance achieved by word spotting methods in identical unbiased conditions. The framework consists of generating systematic distortions on segmentation and retrieving the original queries from the distorted dataset. We apply the framework on the George Washington and Barcelona Marriage Dataset and on several established and state-of-the-art methods. The experiments allow for an estimate of the end-to-end performance of word spotting methods.
