Comparing with the traditional way of manually developing grammar based on linguistic theory, corpus-oriented grammar development is more promising. To develop HPSG grammar through the corpus-oriented way, a treebank is an indispensable part. This paper first compares existing Chinese treebanks and chooses one of them as the basic resource for HPSG grammar development. Then it proposes a new design of part-of-speech tags based on the assumption that it is not only simple enough to reduce ambiguity of morphological analysis as much as possible, but also rich enough for HPSG grammar development. Finally, it introduces some on-going work about utilizing a Chinese scientific paper treebank in HPSG grammar development.
