The index of productive syntax (IPSyn; Scarborough (Applied Psycholinguistics 11:1-22, 1990) is a measure of syntactic development in child language that has been used in research and clinical settings to investigate the grammatical development of various groups of children. However, IPSyn is mostly calculated manually, which is an extremely laborious process. In this article, we describe the AC-IPSyn system, which automatically calculates the IPSyn score for child language transcripts using natural language processing techniques. Our results show that the AC-IPSyn system performs at levels comparable to scores computed manually. The AC-IPSyn system can be downloaded from www.hlt.utdallas.edu/~nisa/ipsyn.html .
生产语法指数（IPSyn；Scarborough（应用心理语言学 11:1-22，1990）是一种衡量儿童语言句法发展的指标，已被用于研究和临床环境中，以调查各种儿童群体的语法发展。然而，IPSyn 主要是手动计算的，这是一个极其繁琐的过程。在本文中，我们描述了 AC-IPSyn 系统，该系统使用自然语言处理技术自动计算儿童语言抄本的 IPSyn 分数。我们的结果表明，AC-IPSyn 系统的性能与手动计算的分数相当。AC-IPSyn 系统可从 www.hlt.utdallas.edu/~nisa/ipsyn.html 下载。
