We propose a set of heuristics for improving annotation quality of very large corpora efficiently. The Xinhua News portion of the Chinese Gigaword Corpus was tagged independently with both the Peking University ICL tagset and the Academia Sinica CKIP tagset. The corpus-based POS tags mapping will serve as the basis of the possible contrast in grammatical systems between PRC and Taiwan. And it can serve as the basic model for mapping between the CKIP and ICL tagging systems for any data.

Chinese writing system is not only used by Chinese but also used by Japanese. The motivation of this paper is to extend the architecture of Hantology which describes the features of Chinese writing system to integrate Japan Kanji and Chinese characters into the same ontology. The problem is Chinese characters adopted by Japan have been changed, thus, the modification of the original architecture of Hantology is needed. A extended architecture consists orthographic, pronunciation, sense and derived lexicon dimensions. is proposed in this paper. The contribution of this study is that the extension architecture of Hantology provides a platform to analyze the variation of Chinese characters used in Japan. The analytic results of variation for a specific Kanji can be integrated into Hantology, so it is easier to study the variation of Chinese characters systematically
