childes-db project stores CHILDES data in a MySQL relational database. The original CHAT files were converted to XML via chatter, a cross-platform application provided by TalkBank. The XML files were then parsed using the Python xml library and subsequently imported into a MySQL database through Django. The annotations and markers from the original CHAT files that were preserved in
childes-db can be found in the table below:
One of the principle design goals for
childes-db is to ensure reproducibility in analyses. The database is versioned and both the API and visualizations provide the database version for each analysis. We recommend that authors report both with their analyses. To reproduce an earlier version of the database, previous releases of the database are directly accessible through both the R and Python APIs.
