vMFD is an easy-to-use Python package for inferring moral appeals from text. It extends eMFD through word embedding and yields superior performance.

Quick start

Download data

The package relies on a pre-calculated data frame that needs to be downloaded. You can use the following command in a Python console or notebook:

import vMFD
vMFD.download_data("word_moral_appeals_googlenews")

You can replace word_moral_appeals_googlenews with other categories. Currently, the following categories are supported:

Calculate moral intuitions

Once the data is downloaded, you can calculate the moral intuitions of any text.

import vMFD

vo = vMFD.vMFD()

# Only calculate the valence
vo.calculate_valence("Trump is the best president")

# Calculate all metrics
vo.calculate_metrics("Trump is the best president")
