首个官方发布的儿童语言依存句法库，助力语言发展研究与计算分析。
UD-English-CHILDES: A Collected Resource of Gold and Silver Universal Dependencies Trees for Child Language Interactions
- 基于CHILDES数据统一标注，构建符合UD标准的金标准句法树库。
- 涵盖11名儿童及照顾者对话，共48,000+句子（236,000词元）。
- 提供金标准与百万级银标准数据，适合语言学与自然语言处理研究。
CHILDES是广泛使用的儿童及亲子对话转录资源。本文介绍首个官方发布的通用依存（Universal Dependencies, UD）句法库——UD-English-CHILDES。该资源源自已有依存标注的CHILDES数据，我们将其统一为一致的标注规范。金标准句法树涵盖11名儿童及其照护者对话的采样语句，共计超过48,000个句子（236,000个词元）。我们在UD v2框架下验证了这些金标准标注，并额外提供了约100万条银标准句子，为计算与语言学研究提供一致的数据资源。
原文摘要 · Abstract (English)
CHILDES is a widely used resource of transcribed child and child-directed speech. This paper introduces UD-English-CHILDES, the first officially released Universal Dependencies (UD) treebank. It is derived from previously dependency-annotated CHILDES data, which we harmonize to follow unified annotation principles. The gold-standard trees encompass utterances sampled from 11 children and their caregivers, totaling over 48K sentences (236K tokens). We validate these gold-standard annotations under the UD v2 framework and provide an additional 1M~silver-standard sentences, offering a consistent resource for computational and linguistic research.
