This repository contains the code and configuration files for transforming the child language acquisition corpora into the ACQDIV database.

If you use the database in your reasearch, please cite as follows:

Download the ACQDIV database (only public corpora):

To request access to the full database including the private corpora (for research purposes only!), please refer to Sabine Stoll. In case of technical questions, please open an issue on this repository.

Our full database consists of the following corpora:

For Windows users, follow the installation/run instructions here: https://github.com/acqdiv/acqdiv/wiki/Installation-Run-instructions-for-Windows

For Mac and Linux user, continue here to run the pipeline yourself:

Create a virtual environment [optional]:

python3 -m venv venv
source venv/bin/activate

You can install the package from PyPI or directly from source:

PyPI

pip install acqdiv

From source

# Clone Repository
git clone [email protected]:acqdiv/acqdiv.git
cd acqdiv

# Install package (for users!)
pip install .

# Developer mode (for developers!)
pip install -r requirements.txt

Run the following script to download the public corpora:

python util/download_public_corpora.py

The corpora are in the folder corpora.

For the private corpora, either place the session files in corpora/<corpus_name>/{cha|toolbox}/ and the metadata files (only Toolbox corpora) in corpora/<corpus_name>/imdi/ or edit the paths to those files in the config.ini (also see below).

Get the configuration file src/acqdiv/config.ini and specify the absolute paths (without trailing slashes) for the corpora directory (corpora_dir) and the directory where the database should be written to (db_dir):

[.global]
# directory containing corpora
corpora_dir = /absolute/path/to/corpora/dir
# directory where the database is written to
db_dir = /absolute/path/to/database/dir
...

Optionally adapt the paths for the individual corpora (sessions and metadata_dir).

Run the pipeline specifying the absolute path to the configuration file:
acqdiv load -c /absolute/path/to/config.ini

Install dependencies

$ R
> install.packages("RSQLite")
> install.packages("rlang")

Navigate to src/acqdiv/database and run:

Rscript sqlite_to_r.R /absolute/path/to/sqlite-DB

Run the unittests:
pytest tests/unittests

Run the integrity tests on the database:
pytest tests/systemtests
