A morphological analysis based method for spelling correction

Xuxen is a spelling checker/corrector for Basque which is going to be comercialized next year. The checker recognizes a word-form if a correct morphological breakdown is allowed. The morphological analysis is based on two-level morphology. The correction method distinguishes between ortho-graphic errors and typographical errors. ? Typographical errors (or misstypings) are uncogni-tive errors which do not follow linguistic criteria. ? Orthographic errors are cognitive errors which occur when the writer does not know or has forgotten the correct spelling for a word. They are more persistent because of their cognitive nature, they leave worse impression and, finally, its treatment is an interest-ing application for language standardization purposes.
