Tools for the Linguistic Analysis of the CHILDES Database

该项目的目标是开发计算工具，以促进对儿童语言数据交换系统数据库中的成绩单数据进行语言分析。这三个领域的目标是词汇，形态句法和语音。 词汇主动性的目标是构建一个键控关系数据库，该数据库将作为数据库中每种主要语言的动态词频词典。该数据库将以电子形式提供给研究人员。该词典的规范形式也将以书籍形式出版。一系列的实证研究的基础上使用这个数据库将完成，以说明研究人员如何词汇数据库可以作为现代跨语言研究的词汇发展的基础。 形态句法倡议的目标是建立工具，以便对儿童发展数据库中的语料库进行自动标记和分析。使用这些解析和标记的结构，将设计额外的程序来计算语素的使用和省略，短语结构，从句结构和句子结构。这些指标可用于跨语言、年龄水平和临床亚型进行比较。 语音学倡议的目标是建立一套开发和分析语音数据库的工具。虽然这些数据最初将以标准的CHILDES文件格式表示，但它们也将被转换成关系数据库，以便于对语音过程进行各种分析。 这项工作的完成将大大提高儿童发展数据库对更先进形式的语言分析的可用性。

The goal of this project is the development of computational tools to facilitate the linguistic analysis of transcript data in the CHILDES (Child Language Data Exchange System) database. The three areas being targeted are lexicon, morphosyntax, and phonology. The goal of the lexical initiative is the construction of a keyed relational database that will serve as a dynamic lexical frequency dictionary for each of the major languages in the database. This database will be available to researchers in electronic form. A canonical form of the dictionary will also be published in book format. A series of demonstration studies based on the use of this database will be completed to illustrate to researchers how a lexical database can serve as the foundation for modern crosslinguistic studies of lexical development. The goal of the morphosyntactic initiative is the construction of tools to permit automatic tagging and parsing of the corpora in the CHILDES database. Using these parsed and tagged structures, additional programs will be designed to compute morpheme usage and omission, phrasal structure, clause structures, and sentence structure. These measures can be used to compare across languages, age levels, and clinical subtypes. The goal of the phonological initiative is the construction of a set of tools for developing and analyzing phonological databases. Although these data will initially be represented in standard CHILDES file format, they will also be converted into a relational database that will facilitate a variety of analyses of phonological processes. The completion of this work will markedly improve the usability of the CHILDES database for more advanced forms of linguistic analysis.
