Spelling Correction for Dialectal Arabic Dictionary Lookup

Abstract

The “Did You Mean...?” system, described in this article, is a spelling corrector for Arabic that is designed specifically for L2 learners of dialectal Arabic in the context of dictionary lookup. The authors use an orthographic density metric to motivate the need for a finer-grained ranking method for candidate words than unweighted Levenshtein edit distance. The Did You Mean...? architecture is described, and the authors show that mean reciprocal rank can be improved by tuning operation weights according to sound confusions, and by anticipating likely spelling variants.

Natural Language Processing for Dialectical Arabic: A Survey

“…A spelling corrector for the Iraqi dialect was presented in (Rytting et al, 2011). An orthographic density metric is used to motivate the need for a fine-grained ranking method for candidate words.…”

Arabic Text Processing Model: Verbs Roots and Conjugation Automation

“…It was evaluated on single-error queries, and the system performance was 28% better than the baseline. It is the first system for a spoken colloquial of the Arabic dialect [4]. As well, Azmi et al designed an algorithm for Arabic spelling error detection and correction, where this method relies on dictionary search.…”

“…The question then becomes how appropriate these figures are when applied to languages other than English. In fact, some researchers have already noticed this potential flaw, and tried to adapt Damerau's findings to their own language, usually by modifying Damerau-Levenstein edit distance (Wagner and Fischer 1974) to match some language-specific data, but still without verifying the appropriateness of Damerau's statistics in the target language (e.g., Rytting et al 2011;Richter, Stranák, and Rosen 2012), or by taking into account some feature of that language, such as the presence of diacritics, for example (e.g., Andrade et al 2012).…”
