Spelling checking using conditional random fields with feature induction for secondary language learners
2016
AbstractThis paper presents a framework for Chinese spelling error detection and correction using conditional random fields (CRFs) with feature induction for secondary language learners. The trend of learning Chinese as second language is increasing recently. CRFs are adopted here as the model that models the global and local information to judge if the word is correct or not. Local features are usually considered to make the decision for intelligent systems. Herein, CRFs are one of the most used statistical approaches those which can adjust the corresponding weights for features to achieve near optimal results. This paper invested an automatic rule induction method to capture the hidden features for spellcheck in Chinese. Considering position information, the features are inducted by counting in the training corpus automatically. Therefore, the CRFs integrate the features and achieve approximated optimum by adjusting the weights corresponding to related features. From the experimental results, we can fin...
