A Multi-Agent System for Detecting and Correcting 'Hidden' Spelling Errors in Arabic Texts

摘要

In this paper, we address the problem of detecting and correcting hidden spelling errors in Arabic texts. Hidden spelling errors are morphologically valid words and therefore they cannot be detected or corrected by conventional spell checking programs. In the work presented here, we investigate this kind of errors as they relate to the Arabic language. We start by proposing a classification of these errors in two main categories: syntactic and semantic, then we present our multi-agent system for hidden spelling errors detection and correction. The multi-agent architecture is justified by the need for collaboration, parallelism and competition, in addition to the need for information exchange between the different analysis phases. Finally, we describe the testing framework used to evaluate the system implemented.
