Abstract

This paper describes details of NTOU Chinese spelling check system in SIGHAN-8 Bakeoff. Besides the basic architecture of the previous system participating in last two CSC tasks, three new preference rules were proposed to deal with Simplified Chinese characters, variants, sentence-final particles, and DE-particles. A new sentence likelihood function was proposed based on frequencies of space-removed version of Google n-gram datasets. Two formal runs were submitted where the best one was created by the system using Google n-gram frequency information.
