摘要：This Paper presents a new, Constraint Grammar based spell and grammar checker for Danish (OrdRet), with a special focus on dyslectic users. The system uses a multi-stage approach, employing both data-driven error lists, phonetic similarity measures and traditional letter matching at the word and chunk level, and CG rules at the contextual level. An ordinary CG parser (DanGram) is used to choose between alternative correction suggestions, and in addition, error types are CG-mapped on existing, but contextually wrong words. An evaluation against hand-marked dyslectic texts shows, that OrdRet finds 68% of errors and achieves ranking-weighted F-Scores of around 49 for this genre.
