Abstract
Comparing with the traditional way of manually developing grammar based on lin- guistic 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 re-duce 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.
