ABSTRACT
The application of the formalism of two-level morphology to Basque and its use in the elaboration of the XUXEN spelling checker/corrector are described. This application is intended to cover a large part of the language.Because Basque is a highly inflected language, the approach of spelling checking and correction has been conceived as a by-product of a general purpose morphological analyzer/generator. This analyzer is taken as a basic tool for current and future work on automatic processing of Basque.An extension for continuation class specifications in order to deal with long-distance dependencies is proposed. This extension consists basically of two features added to the standard formalism which allow the lexicon builder to make explicit the interdependencies of morphemes.User-lexicons can be interactively enriched with new entries enabling the checker from then on to recognize all the possible flexions derived from them.Due to a late process of standardization of the language, writers don't always know the standard form to be used and commit errors. The treatment of these "typical errors" is made in a specific way by means of describing them using the two-level lexicon system. In this sense, XUXEN is intended as a useful tool for standardization purposes of present day written Basque.

SemEval-2010 task 3: cross-lingual word sense disambiguation
SEW '09: Proceedings of the Workshop on Semantic Evaluations: Recent Achievements and Future DirectionsWe propose a multilingual unsupervised Word Sense Disambiguation (WSD) task for a sample of English nouns. Instead of providing manually sensetagged examples for each sense of a polysemous noun, our sense inventory is built up on the basis of the ...
