摘要

在本文中，我们提出了一种基于上下文的方法来校正由OCR系统生成的阿拉伯语单词。这种技术作为一种后处理器来操作，它想要成为通用的。它纠正替代和拒绝错误。阿拉伯文的语言特性在词法分析中非常有用，因此在该方法的发展中被大力利用。替换错误(OCR系统最常犯的错误)被重写到生成规则中，供基于规则的系统用于纠正阿拉伯单词。所开发的方法的第一个版本仅在词法层面上操作，从角度考虑扩展到语言分析的其他层面。

MOrpho-LEXical analysis for correcting OCR-generated Arabic words (MOLEX)

In this paper we present a contextual-based method for correcting Arabic words generated by OCR systems. This technique operates as a post-processor and it wants to be universal. It corrects substitution and rejection errors. The Arabic language properties are very useful in morpho-lexical analysis and therefore they are strongly exploited in the development of the method. The substitution errors, the most frequently committed ones by the OCR systems, are rewritten in production rules to be used by a rule-based system for correcting Arabic words. The first version of the developed method operates only at the morpho-lexical level, the extension to the other levels of language analysis is considered in perspectives.
