An Empirical Study on Building a State-of-the-art English Spelling Error Correction System

In this paper, we present our empirical studies on learning a state-of-the-art English spelling error correction system using Oxford corpora: from detecting spelling errors, building candidate sets, to finally selecting the most likely candidate corrections. With a log-linear model framework, we integrated features based on spelling correction ngrams from supervised data, probabilistic edit-distance, and various distributional similarities. In particular, we did an empirical comparison over these measures, showing the effectiveness for especially the probabilistic edit-distances. We obtained significantly better F-measures, achieving a relative improvement of 49% over Microsoft Word.
