Sinica-IASL Chinese spelling check system at Sighan-7

We developed a Chinese spelling check system for error detection and error correction subtasks in the 2013 SIGHAN-7 Chinese Spelling Check Bake-off. By using the resources of Chinese phonology and orthographic components, our system contains four parts: high confidence pattern matcher, the detection module, the correction module, and the merger. We submitted 2 official runs for both subtasks. The evaluation result show that our system achieved 0.6016 in error detection F-score of subtask 1, and 0.448 in correction accuracy of subtask 2. 1
