Correcting Non-Word Errors Using a Combined Method

The weighted edit distance and metaphone+ algorithm are combined to correct the non-word errors. The speed is also optimized based on the observation that people rarely make mistakes in the initial letter of a word. A spelling checker is designed for an automatic detection and correction system for student essays. To evaluate the algorithm it is compared to some famous systems (MS Word2000, Aspell, winEdt). The results show that our approach is superior to the alternative approaches.
