Running the pipeline

To run the pipeline yourself:

Install the package

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 [e-mail]:uzling/acqdiv.git
cd acqdiv

# Install package (for users!)
pip install .

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

Download the corpora

Create a directory corpora.

For the CHAT corpora:

• Download the CHAT files on the CHILDES TalkBank website (where available) (see Download transcripts link)
• Unzip the data
• Copy the python script src/acqdiv/util/cha_extractor.py into the directory
• Run the script: python cha_extractor.py. A directory cha/ will be created.
• Place the cha/ directory in corpora/<corpus_name>/ (also see the corresponding ini file in src/acqdiv/ini/<corpus_name> for which corpus name to use as a directory name).

For the toolbox corpora:

• Download the toolbox and metadata files (IMDI/CMDI).
• Place the toolbox files in corpora/<corpus_name>/toolbox/ and the IMDI files in corpora/<corpus_name>/imdi/.

Create the database

Get the configuration file src/acqdiv/config.ini and specify the paths for the corpora directory (corpora_dir) and the directory where the database should be written to (db_dir):

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

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

Run the unittests:
$ pytest tests/unittests

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

For more options:
acqdiv load -h
