The Child Language Data Exchange System (CHILDES) offers a database, transcription system (CHAT), and analysis programs (CLAN) for child language research. These tools facilitate data exchange and analysis for researchers worldwide.

Area of Science:

Linguistics
Developmental Psychology
Computational Linguistics

Background:

The Child Language Data Exchange System (CHILDES) was initially proposed to standardize child language transcript data.
Previous work by MacWhinney & Snow (1985) outlined the foundational concepts for this system.

Purpose of the Study:

To present the current state and development of the CHILDES system.
To detail the three core components of the CHILDES system: the database, transcription system, and analysis programs.

Main Methods:

Development and refinement of the CHILDES database for transcript storage.
Implementation of the CHAT system for transcribing and coding child language data.
Creation of the CLAN programs for the analysis of CHAT-formatted files.

Main Results:

The CHILDES system now comprises a comprehensive database of transcripts.
The CHAT system provides a standardized method for data transcription and coding.
The CLAN programs offer robust analytical capabilities for child language data.

Conclusions:

The CHILDES system provides essential tools for international child language research.
Further detailed documentation is available in an upcoming book by MacWhinney.
The integrated CHILDES tools support efficient data sharing and analysis in the field.
