Project description

evekeys: Isolate keywords from an event-based and custom-grouped textual corpus

By Chris Lindgren

Distributed under the BSD 3-clause license. See LICENSE.txt or for details.



A set of functions that uses scikit-learn to conduct a TF-IDF analysis to isolate keywords from event-based documents. It answers the following questions:

  1. What keywords represent a particular period of content?
  2. What keywords represent a particular group of content from a particular period?

It assumes you have:

  • imported your corpus as a pandas DataFrame,
  • included metadata information, such as a list of dates and list of groups to reorganize your corpus, and
  • pre-processed your documents.

It functions only with Python 3.x and is not backwards-compatible.

Warning: evekeys performs little to no custom error-handling, so make sure your inputs are formatted properly. If you have questions, please let me know via email.
