archetyper 1.0.2

Create and quantify 'archetypes' of your constructs. A dictionary-like method run amok!

Archetypes!

This is a library developed to run what might be called a "souped-up dictionary method" for psychological text analysis. Or any kind of text analysis, really.

The core idea behind Archetypes is that you pre-define a set of prototypical sentences that reflect the construct that you are looking to measure in a body of text. Using modern contextual embeddings, then, this library will aggregate your prototypes into an archetypal representation of your construct. Then, you can quantify texts in your corpus for their semantic similarity to your construct(s) of interest.

Note: For the curious: no, this approach not inspired by anything Jungian in nature. In the past, I've said a few things about Jungian archetypes that have inspired scholars to write more than a few frustrated e-mails to me. Apologies to the Jungians.

Installation

This package is easily installable via pip via the following command:

pip install archetyper

Requirements

If you want to run the library without pip installing as shown above, you will need to first install the following packages:

• numpy
• tqdm
• torch
• sentence_transformers
• nltk

You can try to install these all in one go by running the following command from your terminal/cmd:

pip install numpy tqdm torch sentence_transformers nltk

Examples

I have provided an example notebook in this repo that walks through the basic process of using this library, along with demonstrations of a few important "helper" functions to help you evaluate the statistical/psychometric qualities of your archetypes.
