ELFEN - Efficient Linguistic Feature Extraction for Natural Language Datasets

This python package provides efficient linguistic feature extraction for text datasets (i.e. datasets with N text instances, in a tabular structure).

For further information, check the GitHub repository and the documentation

Usage of third-party resources usable in this package

The extraction of psycholinguistic, emotion/lexicon and semantic features relies on third-party resources such as lexicons. Please refer to the original author's licenses and conditions for usage, and cite them if you use the resources through this package in your analyses.

For an overview which features use which resource, and how to export all third-party resource references in a bibtex string, consult the documentation.

Acknowledgements

While all feature extraction functions in this package are written from scratch, the choice of features in the readability and lexical richness feature areas (partially) follows the readability and lexicalrichness python packages.

We use the wn python package to extract Open Multilingual Wordnet synsets.
