Processing Toolbox

Full documentation available at https://ditep.github.io/clinical-toolkit/

This repository contains scripts to preprocess a clinical database. It notably includes functions to process medical text reports, and feature selection on high cardinality categorical features (eg: for medication names).

Many of the scripts rely on scikit-learn API

Disclaimer: This repository has not yet been tested for different databases, and might not be fully compatible for many use cases. However, everyone is welcome to start pull-requests and issues to improve the development of this toolbox.

Installation

The package is not available on PyPI so you need to install it from source.

$ git clone https://github.com/DITEP/clinical-toolkit.git
$ cd preprocessing-toolbox
$ pip install -r requirements.txt
$ pip install . 

You should then run the tests to check the consistency of the installation (see subsection Testing )

Dependencies

The repository is compatible with following versions of packages but may also work with previous versions.

Python 2 has not been tested. Windows support has not yet been tested

• beautifulsoup4==4.6.0
• gensim==3.4.0
• nltk==3.3
• nose==1.3.7
• numpy==1.14.2
• pandas==0.23.0
• requests==2.18.4
• scikit-learn==0.19.1
• scipy==1.1.0

Testing

Unit testing is performed using nose library which is both efficient and easy to use. However good, Nose is now in maintenance mode and the migration to another testing framework will probably be necessary in later development.

To launch the tests of a particular module:

$ cd path/to/module
$ nosetests tests # tests is directory that contains the tests scripts

........
----------------------------------------------------------------------
Ran 8 tests in 0.309s

OK

You can also perform all the tests at once by placing at the root directory

$ nosetests

..................
----------------------------------------------------------------------
Ran 19 tests in 16.747s

OK
